¶ Step 1 - Prepare the Y-axis motor parts
- 1x 40mm NEMA17 Stepper Motor
- y_motor_cage printed part
- 4x M6x12 Cap Head Screw
- 4x M3x8 Cap Head Screw
- 1x 20 Tooth 2GT Timing Pulley for 9mm Belt
- 4x 3030 Square T-Nut - M6
- 1x M8x30 Cap Head Screw
¶ Step 2 - Assemble the Y-axis motor mount - Part 1
- y_motor_cage printed part
- M6x12 Cap Head Screw
- 3030 Square T-Nut - M6
- Loosely thread the 3030 T-Nuts onto the M6x12 screws. Do not tighten them at this point.
- 40mm NEMA17 Stepper Motor
- Install the NEMA17 with its connector pointing downwards
- Fasten the M3x8 screws to secure the stepper motor to the mount
- Take care not to over tighten the M3x8 screws as you can damage the printed part
¶ Step 3 - Assemble the Y-axis motor mount - Part 2
- Assembly from Step 2
- 20 Tooth 2GT Timing Pulley for 9mm Belt
- Position the timing pulley as shown. The end of the stepper shaft should be flush with the end of the pulley
- Fasten the two grub screws on the timing pulley to secure it to the stepper motor shaft
¶ Step 4 - Install the Y-axis motor assembly
- Assembly from Step 3
- V-Minion Frame Assembly
- Install the Y-axis motor assembly onto the V-Minion frame as shown. The 3030 T-nuts will slide into the 3060 extrusion
- M8x30 Cap Head Screw
- Fasten the M8x30 screw through the printed part and into the end of the 3060 extrusion
- Take care not to over tighten the M8x30 screws as you can damage the printed part or the threads in the 3060 extrusion
- Fasten all four M6x12 screws to secure the mount to the frame
- Take care not to over tighten the M6x12 screws as you can damage the printed part
¶ Step 5 - Prepare the Y-axis idler parts
- y_idler printed part
- 4x M6x12 Cap Head Screw
- 4x 3030 Square T-Nut - M6
- 1x M5x50 Cap Head Screw
- 2x M8x30 Cap Head Screw
- 2x Micro Precision Shim
- 1x 20 Tooth 2GT Idler Pulley for 9mm Belt
- 1x M5 Nylon Locking Hex Nut
¶ Step 6 - Assemble the Y-axis idler - Part 1
- y_idler printed part
- M5 Nylon Locking Hex Nut
- Insert the M5 nylon locking nut into the printed part as shown
- M5x50 Cap Head Screw
- Install one precision micro shim onto the M5x50 screw
- Install the toothed 2GT idler onto the M5x50 screw
- Insert the M5x50 cap head screw further in preparation for the next step
¶ Step 7 - Assemble the Y-axis idler - Part 2
- Micro Precision Shim
- Install the second precision micro shim onto the M5x50 screw
- The assembly should look as shown, a micro precision shim on either side of the toothed idler
- Fasten the M5x50 screw through the y_idler, into the M5 nylon lock nut
- Check that the toothed idler rotates without binding. If the idler is difficult to rotate, loosen the M5x50 screw until the idler rotates smoothly
¶ Step 8 - Assemble the Y-axis idler - Part 3
- Assembly from Step 7
- M6x12 Cap Head Screw
- 3030 Square T-Nut - M6
- Loosely thread the 3030 T-Nuts onto the M6x12 screws. Do not tighten them at this point
- V-Minion Frame Assembly
- Install the Y-axis idler assembly onto the V-Minion frame as shown. The 3030 T-nuts will slide into the 3060 extrusion
- If you have any problems aligning all of the square t-nuts at the same time, you can alternately pre-install some, or all of them, into the extrusion and add the screws afterwards
¶ Step 9 - Install the Y-axis idler
- M8x30 Cap Head Screw
- Fasten the M8x30 screw through the printed part and into the end of the 3060 extrusion
- Take care not to over tighten the M8x30 screws as you can damage the printed part or the threads in the 3060 extrusion
- Fasten all four M6x12 screws to secure the mount to the frame
- Take care not to over tighten the M6x12 screws as you can damage the printed part
