Printrbot Plus 1306 Assembly
Printrbot Plus 1306 Assembly Printrbot Plus 1306 Assembly We are going to build a Printrbot LC or Plus v2 from beginning to end! The differences between the LC and Plus are very minimal. We will point out the differences as you complete this guide. Written By: Brook Drumm INTRODUCTION There are a lot of steps, but each picture is one little baby step of assembly. You will be rolling through these steps at a good clip! You can do it! TOOLS: Electric screwdriver with clutch (1) Exacto knife (1) Metric Allen wrench set (1) Needle nosed pliers (1) Open end wrenches (1) Screwdriver (1) utility knife (1) © 2015 help.printrbot.com Page 1 of 51 Printrbot Plus 1306 Assembly Step 1 — Plus v2 (Model 1306) Quite literally, the Plus v2 and the LC v2 have identical nuts and bolts packs and they assemble the exact same way. I will update the pictures just to be really accurate, but you can assemble an Plus v2 based on LC v2 guide. Now on to the guide... Step 2 NOTE - If you have the older Y-axis wooden bearing assembly skip this step and go to step 3. We will begin with the base and the Y-axis bearing blocks We want to make sure the top of our base is in the correct orientation. The top of this piece will have the two small triangles pointing toward you (green circles) and the cutout for the Z-axis end stop will be on the left (red box). 4 - M4 10mm per Y-axis © 2015 help.printrbot.com Page 2 of 51 Printrbot Plus 1306 Assembly Step 3 NOTE - If you have the Y-axis bearing block please skip to step 5 We will start with the BASE Y Bearing Sleeves: 8x 1.25" 6-32 screws (4 each side) 4 LM8UU bearings (2 per side) Step 4 8x 6-32 nuts (4 each side) Attach Assembled Y Bearing Holders to back panel of base unit. Tighten everything down. © 2015 help.printrbot.com Page 3 of 51 Printrbot Plus 1306 Assembly Step 5 NOTE - If you have the older Y-axis bearing assembly, you can see photos of your build for this step on step 7 The top holes need to line up - if they don't you have it backwards. 4 - M4 10mm (2 per side) to mount the aluminum blocks. Use 3mm Allen Wrench to tighten. Step 6 Time to insert Z-axis smooth rod into aluminum blocks from previous step. Plus kits will use 12mm smooth rod. LC kits will use 8mm smooth rod. 4 - M6 4 or 6mm set screw (2 per side) will firmly secure the Z-axis rods in the block If it is difficult to insert these rods by hand you my need to use a rubber mallet or hammer to guide the rods into the blocks. © 2015 help.printrbot.com Page 4 of 51 Printrbot Plus 1306 Assembly Step 7 NOTE - if you have the Y-axis bearing block please skip to step 9 The 2 aluminum Z blocks greatly increase the rigidity of the printer in this second revision. Step 8 The top holes need to line up - if they don't you have it in backwards. 4x M4 10mm screws (2 per side) to mount the aluminum blocks. Use 3mm allen wrench. 4x M6 6mm set screws (2 per side) will firmly secure the Z rods when we are ready to add them. © 2015 help.printrbot.com Page 5 of 51 Printrbot Plus 1306 Assembly Step 9 NOTE - Moving forward in this guide you will continue to see photos with old Y-axis bearing wooden assembly. The Y motor has a spacer to make it ride a bit lower than the Z motors. Mount your belt pulley on the Y motor. Be careful NOT TO OVERTIGHTEN the set screw. Use a 1/16 or 1.5mm allen wrench. 4x M3 16mm screws will secure the motor. Step 10 For two Y belt idler assemblies, you will need: 2x .75" 6-32 screw 2x #6 washer 2x 8mm Nylon spacer 2x 608 bearing with Delrin Idler 4x 1/4" washer 2x 6-32 nuts © 2015 help.printrbot.com Page 6 of 51 Printrbot Plus 1306 Assembly Step 11 Y End Stop 2 - M2 10mm or 12mm screws Photos show the larger M3 screws but now we supply smaller M2 screws that work much better. Step 12 A screw will be coming up through this hole soon (red box), so either insulate the endstop with tape or just gently bend it up out of the way a bit. Add the two 12mm smooth rods for the Z axis Tighten the set screws. Make sure you have those mounted on the outsides near the Z motors - not the inside. © 2015 help.printrbot.com Page 7 of 51 Printrbot Plus 1306 Assembly Step 13 Mounting the Printrboard 4x 1" 6-32 screws 4x 16mm Nylon Spacers Squishing the nylon spacers a little with pliers will allow the spacers to grip the screws and not fall off so you can easily mount the Printrboard to the base plate. Step 14 Pay attention to the Y axis end stop wire so you don't have to fight with it later. Remember the side of the electronics board with the SD slot and USB connector will be facing the back side of the printer. © 2015 help.printrbot.com Page 8 of 51 Printrbot Plus 1306 Assembly Step 15 Mount the two Z Motors 8x M3 8mm screws (4 per side) 2 small vinyl tubes (1 per side) Step 16 Get all your wiring dialed in for the motors and endstop. © 2015 help.printrbot.com Page 9 of 51 Printrbot Plus 1306 Assembly Step 17 The Y motor will plug into the port labeled "Y-MOT" Plug in the Y end stop E-MOT and Z-MOT trimpots should already be turned to about 2 o'clock but if not you can adjust it with a small electricians flat head screwdriver. Y-MOT and X-MOT should be stationed at 12 o'clock. Step 18 Take part # 423 and mount on power connector. © 2015 help.printrbot.com Page 10 of 51 Printrbot Plus 1306 Assembly Step 19 Plus v2 Base - front, back and sides. 4x M4 10mm screws for securing side to the aluminum blocks 2x M3 10mm screws for the Z end stop Step 20 4x M4 10mm screws for securing side to the aluminum blocks © 2015 help.printrbot.com Page 11 of 51 Printrbot Plus 1306 Assembly Step 21 May be a tight fit getting power connectors onto the back plate of the base. Gently use pliers if needed. Plug Y-Power adapter into electronics board. Step 22 8x .5" 6-32 screws 8x 6-32 nuts © 2015 help.printrbot.com Page 12 of 51 Printrbot Plus 1306 Assembly Step 23 The Base is done!!!!! Step 24 X Carriage 8x 1" 6-32 screws 4x LM8UU bearings Note - It is wise to place two of your 8mm smooth rods through the LM8UU bearings while screwing the 1" screws through the X carriage. This way you'll be sure that they line up properly. © 2015 help.printrbot.com Page 13 of 51 Printrbot Plus 1306 Assembly Step 25 Extruder Mount 4x .5" 6-32 screws 4x 6-32 nuts Part #435 is sandwiched between #431 and #429. Note - the spacing between the holes and the edge of part #435 is thinner at the bottom than it is at the top. This is intentional for lining up this assembly (yellow box). Step 26 4x .75" 6-32 screws © 2015 help.printrbot.com Page 14 of 51 Printrbot Plus 1306 Assembly Step 27 4 - 8 mm M3 bolts M2 bolts will go in from the backside of the fan through the wood. Once assembled set aside until extruder is assembled and mounted on X carriage. Step 28 Soon to be updated. X End Stop Set Screw 1x .75" 6-32 screw 1x 6-32 locking nut © 2015 help.printrbot.com Page 15 of 51 Printrbot Plus 1306 Assembly Step 29 Thumbscrews go together with a little super glue or any glue, really. Best to use something suited for wood though. Step 30 1x 2.5" 6-32 screw 2x 6-32 nuts © 2015 help.printrbot.com Page 16 of 51 Printrbot Plus 1306 Assembly Step 31 3x .5" 6-32 screws 3x 6-32 nuts Step 32 The backing plate with all the holes has large holes that line up with the screw heads on the plate with the belt tensioner mount. 4 - .75" 6-32 bolts secure the belt tensioner assembly to the X carriage (red circles). © 2015 help.printrbot.com Page 17 of 51 Printrbot Plus 1306 Assembly Step 33 2x 1.5" 6-32 screws 2x star washers 2x 6-32 nuts Step 34 Left Bridge 1x 2.5" 6-32 screw 1x .75" 6-32 screw 1x 6-32 locking nut (for the end of the set screw) The long screw will go through the locking 6-32 nut (Nylock). the short screw holds the 3 layers together. © 2015 help.printrbot.com Page 18 of 51 Printrbot Plus 1306 Assembly Step 35 Here is the Z set screw piece all put together. To mount it to the motor plate, you will need.... 1x 1" 6-32 screw 1x 6-32 nut Step 36 4x 1" 6-32 screws 2x LME12UU bearings PLUS LME12UU bearings pictured in lower right corner of picture 1 © 2015 help.printrbot.com Page 19 of 51 Printrbot Plus 1306 Assembly Step 37 1x .75" 6-32 screw 1x .5 6-32 screw 2x 6-32 nuts [Editorial's note - need pictures with LM12UU bearings] Step 38 5x 1.5" 6-32 screws 1x 3" 6-32 screw Make sure set screw on pulley is securing to flattened portion of the motor shaft. DO NOT OVER-TIGHTEN the pulley set screw! [Editorial's note - need pictures with LM12UU bearings] © 2015 help.printrbot.com Page 20 of 51 Printrbot Plus 1306 Assembly Step 39 4x M3 8mm 1x .5" 6-32 screw 2x 6-32 nut One of the 6-32 nuts goes on the long 3" screw to hold the motor on securely. See the red circle on the third picture. [Editorial's note - need pictures with LM12UU bearings] Step 40 Even though the pictures don't show it, there needs to be a 6-32 nut where the red circle is in the 3rd picture. [Editorial's note - need pictures with LM12UU bearings] © 2015 help.printrbot.com Page 21 of 51 Printrbot Plus 1306 Assembly Step 41 The 2 10" smooth bars for the X carriage will push into place as long as you have some slack on the 6 screws that thread through the front plate. [Editorial's note - need pictures with LM12UU bearings] Step 42 The bar ends should just peek out past the last holes that screw down to hold them in place. Once the bars are in, tighten the 6 screws. It will need to be very tight, but don't go so tight that it deforms the top plate. © 2015 help.printrbot.com Page 22 of 51 Printrbot Plus 1306 Assembly Step 43 Right Bridge 4x 1" 6-32 screws 1x 1.25" 5/16"-18 button head bolt 1x 5/16"-18 nut 1x 1" 6-32 screw [not shown] (for the hole all the way to the right) 1x 6-32 nut [not shown] (for the 1" 6-32 screw mentioned above) 2x LM12UU bearings [Editorial's note - need pictures with LM12UU bearings] Step 44 The 3rd picture shows the 1" bolt on the right - it will require a 6-32 nut on the back. [Editorial's note - need pictures with LM12UU bearings] © 2015 help.printrbot.com Page 23 of 51 Printrbot Plus 1306 Assembly Step 45 1x 608 bearing with Delrin idler 1x 5/16"-18 locking nut The bearing is best oriented this way. There is that 6-32 nut I was talking about earlier. :) [Editorial's note - need pictures with LM12UU bearings] © 2015 help.printrbot.com Page 24 of 51 Printrbot Plus 1306 Assembly Step 46 6x 1.5" 6-32 screws Mount the X carriage on the bars before you put the bars through the right bridge shown here. Leave these loose enough to get the bars through. Make sure you are extremely careful to get the distance correct between the bearing holes on each side. The distance MUST MATCH EXACTLY with the distance between the Z bars already mounted to the base. Be careful not to force the bearings onto the Z bars - if you force them, you could pop out some of the tiny ball bearings inside the LM8UU 8mm linear bearings. The Right block should be loose enough on the X bars to push the whole assembly down to the bottom and let it self adjust it's width apart. You can work the top of the Z bars back and forth to help it adjust. Once it slides smoothly up and down, tighten all the screws down and lock in the X bars. Take a close look, while you are at it, to be sure the X bars are parallel to the top of the base. Sometimes, in the build process, the X assembly (the bridge) gets slightly cocked forcing one side of the bridge to ride lower or higher. Just loosen the front bolts on both side enough to force it straight and re-tighten. © 2015 help.printrbot.com Page 25 of 51 Printrbot Plus 1306 Assembly Step 47 Test all the movement now to be sure everything runs smoothly. [Editorial's note - need pictures with fan mount] Step 48 Print Bed 8x .5" 6-32 screws 4x 6-32 nuts 1x 1" 6-32 screw [not shown] 1x 6-32 locking nut [not shown] There is a set screw hole for the Y axis end stop on the top left of the front panel. It accepts the 1" 6-32 screw and a 6-32 locking nut on the end (these are mentioned above). © 2015 help.printrbot.com Page 26 of 51 Printrbot Plus 1306 Assembly Step 49 You will need to mount the print bed on the Y bars to mount the front panel. BE CAREFUL pushing them through the bearings - be gentle and wiggle them through lightly. You don't want to lose any tiny ball bearings! For the Belt Tensioner at the back, you will need: 2x 1.5" 6-32 screws 2 star washers (or locking washers) 2x 6-32 nuts 1x .5" 6-32 screw 1x 6-32 nut The last two items are for the little piece pictured in the 3rd picture. © 2015 help.printrbot.com Page 27 of 51 Printrbot Plus 1306 Assembly Step 50 Use the shorter of your two belts and thread your belt like so... The belt will loop through the front plate and be zip tied together. The belt teeth should face each other and interlock for added hold - before you zip tie them together. The belt will lock into the tensioner on the back plateas illustrated. You might have to adjust the length of the belt a couple times to find the sweet spot for the belt to lock into the "T". You need enough room to tension the belt later, but if you don't leave enough length, it will be hard to reach the 2 screws that accept the thumbscrews. PS: Looks like a cartoon dog face. :) Step 51 Be patient and find that sweet spot for the belt to interlock with the "T". The wood thumbscrews glue together with superglue. Then you can press the 6-32 nuts into their places. © 2015 help.printrbot.com Page 28 of 51 Printrbot Plus 1306 Assembly Step 52 Wait to trim the belt until you are absolutely sure you have the right length. I try and leave a little extra belt just in case. Be sure any extra belt does not interfere with the movement of the bed. © 2015 help.printrbot.com Page 29 of 51 Printrbot Plus 1306 Assembly Step 53 4x M3 10mm screws 4x M3 nuts Try to place the thermistor exactly where it is shown in the picture. This should afford the best accuracy on the heat bed reading. NOTE: Your temperature readings in software could be inaccurate. Try printing at 65-70 C first. THen step up the temperature 5 degrees at a time until you get good results and everything sticks nicely. IF the software is not reporting the correct temperature - or you set the temperature too high, it may not be able to reach the temp you have requested it to reach. Now is a great time to insulate the bottom of the red heat bed. BE VERY CAREFUL NOT TO SHORT OUT THE WIRES SOLDERED TO THE BOARD! We have heard of people using all sorts of insulators. If you decide to use one, choose a radiant barrier with the brown paper backing facing up so the aluminum will not short out the heat bed power wires. © 2015 help.printrbot.com Page 30 of 51 Printrbot Plus 1306 Assembly Step 54 The 4x 10mm screws and M3 nuts should only be used if you do not use glass on top of the heat bed. If you do use glass, use binder clips to clip and hold the glass and heat bed to the wooden print bed. Kapton tape should be used as the top layer. If you don't use glass, mount the Kapton tape square on the red heated bed. If you do use glass, mount it on top of the glass. Glass is recommended to keep the print surface really flat. You will have MUCH better results if you use glass. We have chosen not to ship glass with our printers for safety reasons. Step 55 To spring the top print bed, you will need: 4x 1.25" 6-32 screw 4x star washer 4x small spring 4x 6-32 nut © 2015 help.printrbot.com Page 31 of 51 Printrbot Plus 1306 Assembly Step 56 Screw the thumbscrew down enough to get some tension in the spring. Do your best to level the bed - just eye it. You will level it much more precisely later. Step 57 The wires from the heat bed will zip tie to the square holes in the wood print bed. The heat bed power and thermistor plug into the plugs near the front. Read the labels carefully. It may be a tight fit, but you can do it. © 2015 help.printrbot.com Page 32 of 51 Printrbot Plus 1306 Assembly Step 58 The thermistor plugs in directly across the board from the Heat bed power. It is the one nearest the front and is right next to the reset switch. Step 59 Threaded Z-Rods 8x .75" 6-32 screws 8x 6-32 nuts © 2015 help.printrbot.com Page 33 of 51 Printrbot Plus 1306 Assembly Step 60 Make sure the couplers are spread apart enough to fit on loosely. You don't want to push the vinyl tubing down and create friction by having the vinyl drag on the top plate of the motor. Step 61 1x 5/16"-18 nut is used for each side of the bridge to lift the Z axis up and down. If you use acme rod as your threaded rod for the Z, use 1/4" -12 Acme rod. The nut for that Acme rod is the exact size of a 5/16"-18 nut. It just works. We have tested it and the steps per mm is 2020. © 2015 help.printrbot.com Page 34 of 51 Printrbot Plus 1306 Assembly Step 62 Extruder 2x 3" 6-32 8x 1" 6-32 3x .5" 6-32 2x 6-32 nuts 2x 6-32 locking nuts 5x 1/4" washers; 1x 5/16-18 locking nut; 1x 1.25 5/16"-18 bolt ; 1x hobbed bolt; 2x .75" springs; 3x 608 bearings Extruder Build Video vimeo.com/62332731 Step 63 Continue placing pieces on top of each other in numerical order as pictured. © 2015 help.printrbot.com Page 35 of 51 Printrbot Plus 1306 Assembly Step 64 Place #2 on top of #1, #3 on top of #2, and so on. Secure the layers with 3 1" 6-32 bolts from #5 layer. Step 65 Flip over the assembly and from layer #1 screw in two 1" 6-32 bolts and one .5" 6-32 bolt. © 2015 help.printrbot.com Page 36 of 51 Printrbot Plus 1306 Assembly Step 66 Place the 608 bearings in layers #5 and #1. Step 67 Secure pieces together with two .5" 6-32 bolts and two 6-32 hex nuts. One 5/16" bolt, four 1/4" washers, and one 608 bearing. Two washers go on each side of the 608 bearing. © 2015 help.printrbot.com Page 37 of 51 Printrbot Plus 1306 Assembly Step 68 One 1" 6-32 bolt (green box). Two 3" 6-32 bolts with two 1" springs and two 6-32 nylock nuts. Step 69 1 - Injection molded large gear 1 - Hobbed Bolt Insert hobbed bolt through center of large gear. © 2015 help.printrbot.com Page 38 of 51 Printrbot Plus 1306 Assembly Step 70 1 - 1/4" washer 1 - 5/16" hex nut (locking) Center the cerated portion of the hobbed bolt to the slot in the wooden assembly. You may need to use the washer in order to center or you may not need it (green box). Keep the hobbed bolt teeth CLEAN or the filament will not feed properly. When the teeth are clogged you will not get any traction on your filament. #1 reason the hobbed bolt slips and strips the filament--- you are running your hot end to cool.... slice your model with a higher temperature. It is safe to go up to 230 C. Try increasing your heat in 5 degree increments until you find the sweet spot for your printer. #2 reason your filament isn't feeding through --- your tension on your 3" screws is wrong, either too tight or too loose. #3 reason your filament isn't feeding through --- your small gear is slipping. Check your set screw and inspect your small gear on the extruder motor. © 2015 help.printrbot.com Page 39 of 51 Printrbot Plus 1306 Assembly Step 71 1 - injection molded small gear Photo #2 - align the flattened portion of the motor shaft to the flattened portion of the small gear. Press on the small gear leaving about 2 mm between the base of the small gear and the motor. Step 72 Attach the extruder motor onto the extruder assembly with one 8mm M3 bolt (green box). Leave the other two M3 bolts out for now. You will need to be able to access a hole below the motor to attach it onto the X carriage. Note - it is best to have the extruder motor wiring to come off down toward the extruder assembly as shown in photo #3. © 2015 help.printrbot.com Page 40 of 51 Printrbot Plus 1306 Assembly Step 73 Mounting the Extruder & Cable management. If you don't have a small hole in the center of the number 5 on the back of the extruder, drill a hole and use a .75" 6-32 screw as an anchor for your zip ties to secure your hotend & motor wires. This will keep them from getting in between the left bridge and the X carriage on the left and reduce wire strain on the motor wires. Step 74 The 1" 6-32 screws that mount the extruder to the extruder mount are a bit hard to reach with a screw driver. One requires you swing the motor out of the way (leave the bottom M3 8mm screw attached). The other can be reached straight down through the idler when it is closed. © 2015 help.printrbot.com Page 41 of 51 Printrbot Plus 1306 Assembly Step 75 2x 1" 6-32 screws 2x 6-32 nuts 2x #6 washers The washers are needed because of the large holes in the extruder base. Be gentle with these connectors - they are fragile and critical. Make sure they are not under any strain or stress. The connector with the clear shielding connects to the white/black hotend thermistor cable (yellow box). The connector with the black shielding connects to the red/black hotend power cable (green box). Connect fan wiring to fan extension cable. Be sure to match color of wires on connector. © 2015 help.printrbot.com Page 42 of 51 Printrbot Plus 1306 Assembly Step 76 One of the extruder motor mount screws is hidden. You have to rotate the large gear just right to gain access to it. Optional: I have been untwisting the hot end thermistor and power wires enough to squeeze them in under the motor - in between the motor and the extruder base. Why? They can be pinned (with some difficulty) in a fashion that allows proper slack to protect the connections to the hotend. Did I mention not to strain these wires? Step 77 Whether you tucked the wires under the motors or snuck them around the back, your 2nd line of defense against wire strain on the hot end wires - and the motor wires - is this little hack. We added a small hole to the bottom of the "5" on the back extruder plate. A .75" 6-32 screw will screw in there to be our anchor. 2 zip ties will work together to secure our wires and reduce strain. © 2015 help.printrbot.com Page 43 of 51 Printrbot Plus 1306 Assembly Step 78 Zip ties every 5 or 6 inches please. Of course, you could also use cable wrap. Step 79 Bridge Wiring and Cable Management 2x M3 8mm screws When I took this picture, I didn't have any proper sized screws to secure the X end stop limit switch to the left bridge. I drilled out the holes on the limit switch to accept M3 8mm screws. (Fingers crossed) Your kit will ship with properly sized screws to mount this without any drilling. One other short term fix - source your own screws for this step... admittedly, we know you don't want to hear this. I just wanted to be straight forward in what is going on here. © 2015 help.printrbot.com Page 44 of 51 Printrbot Plus 1306 Assembly Step 80 This fancy part was, arguably, not even needed, but it bugged me not having a way to adjust it. Step 81 Your heat bed cables and your bridge cables will all fit through here, but not all at once. It makes for a very clean final product. © 2015 help.printrbot.com Page 45 of 51 Printrbot Plus 1306 Assembly Step 82 Of the two motor wires coming from the bridge, the short motor wire will be the extruder and the longer one will be the X motor. Step 83 The little metal pins that can be seen peeking through the side of the black motor connector (second picture) should face the inside of the board. As picture 3 shows, that puts the red wire on the right. © 2015 help.printrbot.com Page 46 of 51 Printrbot Plus 1306 Assembly Step 84 Yes, it is a lot of wires in a small place, but it works and allows the greatest flexibility to switch out any motor with a replacement without regard for wire length. Same goes for the limit switches. © 2015 help.printrbot.com Page 47 of 51 Printrbot Plus 1306 Assembly Step 85 Leveling the Bed #1 Rule of 3D printing: The print bed must be flat. Use the 4 thumbscrews and compress your leveling springs about half way - you want some decent tension holding that bed up so it doesn't wobble or shake a nut loose. After you visually level the bed... #2 Rule of 3D printing: your X bars must be parallel with the top of your leveled print bed. Move the printhead until its just above the print bed all the way to the left. Use the threaded rod on each side to bring the X axis parallel to the print bed. Move the carriage manually back and forth checking each side until you are sure the X is parallel - equal distance above the platform. TIP: if you don't have glass installed (optional), you may have a slight crown in the center of your heat bed. We recommend adding simple window glass to the top, held down by binder clips. Lowes or Home Depot will cut it to size and sell it to you cheap (~$3.00). © 2015 help.printrbot.com Page 48 of 51 Printrbot Plus 1306 Assembly Step 86 Correct connectors from power supply. Good practice - use the connector with the shortest distance of wiring back to the power supply (green box). Use the jumper cable to jump a green and black wire (orange box).

You did it! © 2015 help.printrbot.com Page 49 of 51 Printrbot Plus 1306 Assembly Step 88 More Printrbot LC / Plus v2 mug shots. Step 89 More shots of the LC and Plus. © 2015 help.printrbot.com Page 50 of 51 Printrbot Plus 1306 Assembly Step 90 For more help: Printrbot.com help.printrbot.com and also a thriving community of Printrbot advocated lives at printrbottalk.com The Plus is actually pretty easy to build. It may look like a lot of parts in the bags, but it actually only has 4 main sections. Taking them one at a time and covering them thoroughly - its a breeze.
