2 Step 1 Simple Maker's Edition v3 (Model 1401) This guide is for the 2014 Printrbot Simple. If your kit is stamped with a "1405" on wood part #7. Please see Simple 1405 Assembly Laser Cut Wood Diagram. If you are assembling Simple with the wood bed and extruder, you will have the 2013 wood plate. If you have the Alu Extruder and bed, this wood plate will not be included in your kit Printrbot Simple Bill of Materials ( ) Download Simple Maker Firmware, should you need to flash your board in the future.

Make sure to cut the plates apart on a surface that will be okay to have knife marks in it. New line.

3 Step 2 Your Printrbot Simple wooden pieces will come in 5 plates that you will then need to use a utility knife to separate. You will use a utility knife to cut one side of the wood, flip over the plate, and cut through the opposite side of the tab. Make sure to cut the plates apart on a surface that will be okay to have knife marks in it. New line.note - Do not snap the pieces apart with your hands as the wood will tend to remove top or bottom layers of the plywood. NOTE- You can use a nail file or sandpaper to smooth the connection points in the wood help.printrbot.com Page 3 of 39

6 Step rubber tubing 2 - sandpaper pulley Dab some super glue onto the rubber tubing. Place the sandpaper pulley onto the rubber tubing until it is flush with one side of rubber tubing. Once dry move to next step help.printrbot.com Page 6 of 39

NOTE - the X axis motor pulley will need to be pressed about 2-3mm past the motor shaft (red box).

7 Step 7 Once dry, press the rubber tubing onto the motor shaft of one of your large motors. X axis will be a large motor and the Y axis will be a small motor. NOTE - the X axis motor pulley will need to be pressed about 2-3mm past the motor shaft (red box). It is a good idea to label the motor for later steps in the build. Be sure to zip tie the base of the rubber tubing onto the motor shaft to prevent slippage help.printrbot.com Page 7 of 39

Shown on the right, photo #2. Label your Y-axis motor.

8 Step 8 Go ahead and do the Y-axis (small) motor as well. You have probably noticed that there are two small motors pictured in these instructions. You could have received one with a black connector and the shorter motor shaft OR yours could have a white connector and a longer motor shaft. If your Y-axis motor has a black connector, you will want to push the black tubing all the way down on the motor shaft. Shown on the left, photo #2 - black square. If your Y-axis motor has a white connectro, you will want to leave about 5mm of space on the bottom of the motor shaft. Shown on the right, photo #2. Label your Y-axis motor. Step M3 10mm bolt X axis large motor Attach motor to Part #9 with four M3 10mm bolts. You will want to make sure that the wiring is going off of the left side of part #9 as shown in red box in photo # help.printrbot.com Page 8 of 39

10 Step M3 16mm bolt 2 - M3 hex nut Take X axis/z axis assembly and mount onto part #7 with two M3 16mm bolts and two M3 hex nuts. NOTE - Make sure to route the wiring for the X axis end stop through the hole in part #7 for the Z-axis motor, shown in photo #3 (red box) help.printrbot.com Page 10 of 39

Step 13 Wiring Managment Step Because there is so much length on the large motors, we will need to

First make sure about 4-5 inches of length comes out of the hole on part #8 as shown in photo #2.

Take the Z axis' zip tied wires and press into the gap between the two motors, shown in photo #2.

11 Step 13 Wiring Managment Step Because there is so much length on the large motors, we will need to manage them so your Printrbot Simple looks nice and neat. Individually wrap each motor's wires. First make sure about 4-5 inches of length comes out of the hole on part #8 as shown in photo #2. You can use three fingers for wrapping as shown in photo #1. Zip tie each batch of wiring. Take the Z axis' zip tied wires and press into the gap between the two motors, shown in photo #2. Take X axis' zip tied wires and place on the side of both motors as shown in photo # help.printrbot.com Page 11 of 39

12 Step 14 Attach power adapter onto plate (wood part #5) with zip tie. You will want to back the nut on the power adapter off enough for the zip tie to fit in between the nut and the plastic housing. Zip tie nub is on the same side as the power adapter. See photo #2. Step 15 Close in wiring from step 12 with part # M3 16mm screws 5 - M3 Hex Nuts Make sure that the wiring for the power adapter is routed through the provided slot before securing with M3 screws (red box) help.printrbot.com Page 12 of 39

Step 16 Attach part #6 with M3 16mm screws.

NOTE: The zip ties do not need to be extremely tight.

13 Step 16 Attach part #6 with M3 16mm screws. 5 - M3 16mm screws 5 - M3 Hex Nuts Step Zip ties Before you zip tie the electronics board on to the wood it is easiest to connect the Power adapter (red box) and the Extruder Power (green box) while the board is loose. Only use three zip ties at this point to attach electronics board (orange circles). You will attach the final corner later in this build. NOTE: The zip ties do not need to be extremely tight. The Printrboard should be secure with snug zip ties, but too much tension could put undue stress on it help.printrbot.com Page 13 of 39

14 Step 18 Once base assembly is together, time to connect the two end stops to the electronics board. The Z-axis end stop can be identified as the one with the 3" wiring, much shorter than the other end stops. Connect the Z axis end stop to the electronics board "Z-STOP" (red box). Connect the X axis end stop to the electronics board "X-STOP" (green box). Step 19 Install the 10" smooth rods. Use hammer or rubber mallet to get smooth rods through the two wood plates. Make sure to provide support under the bottom plate so you don't blow out the bottom of the plate, shown in photo #2. Once the rods are seated flush with the bottom side of the base take two M3 10mm bolts to lock the bars in place. Photo # help.printrbot.com Page 14 of 39

This screw hits the X-axis end stop so do not screw it all the way into the wood seating the head of the screw completely. You will want to leave some length on the screw as shown in photo #3. Take the four M3 locking hex nuts and press them into the bottom of the print platform in the engraved corners of the piece with a pair of pliers or channel locks evenly. NOTE - Be sure to face the nylon portion of the locking hex nuts out of the wood. Step Zip ties 2-6.5" 8mm smooth rod Make sure the M3 10mm bolt is on the left as you assemble the bed platform, shown in photo #3 (red box).

This length will the point at which you will tie off the new X axis tensioning assembly. NOTE - Tie the knot on the bottom side of the tensioning assembly. This way it will clear below the print platform (Part #2). Step 25 Once you've tied off both sides, you will want to wrap the fishing line around the sandpaper pulley two full wraps. If you've measured the line at 9-1/8 inches you should have to stretch the tensioning assembly onto the left side of the print platform. Take the zip tie and secure the tensioning assembly onto the print platform using the slots at the end of the assembly. Screw the M3 16mm bolt clockwise to tighten the fishing line to remove any slack in the line. (line should be fairly tight) 2014 help.printrbot.com Page 17 of 39

The four nylon washers will seat between the head of the M3 screws and the metal bed

This is the print bed so you will want to space the two wood pieces with four bed springs.

18 Step M3 20mm screws 4 - bed springs 4 - nylon spacers Attach the Metal Bed onto #2 with four 20mm M3 screws. The four nylon washers will seat between the head of the M3 screws and the metal bed (photo #3). This is the print bed so you will want to space the two wood pieces with four bed springs. Thread the four 20mm M3 screws into the M3 locking hex nuts pressed into #2. If you do not have the metal print bed, substitute wood part 1. You will not have the nylon spacers included in your kit help.printrbot.com Page 18 of 39
