Z-Axis Motor Replacement
This guide covers replacing Z-axis motors on the Vision Miner 22IDEX V4. The printer has three Z-axis motors which provide bed movement up and down. They are placed just under the Z-axis lead screws: two in the front machine corners and one at the middle of the back side. The motors are permanently connected to the lead screw and cannot be disassembled without damage.
Before you begin - safety and risk
Read the Safety - Before You Begin article to understand the hazards involved in working on the Vision Miner 22IDEX V4 - including electrical, thermal, mechanical, and chemical risks. All procedures in this wiki are provided as recommendations only. By choosing to follow any procedure, you do so at your own risk.
Tools and Materials
- 2 mm hex driver
- 7 mm wrench (M4)
- Replacement Z-Lead Screw Motor
- Zip ties (if using build plate securing method)
Replacement Procedure
- Power off the machine and unplug the power cord from the wall outlet.
- Identify the motor(s) that need to be replaced and provide access to them. Ensure the machine is placed securely with enough space (at least 60 cm) underneath the motor. Do not rotate the machine on its side.
-
Prepare the build plate. Choose one of two options:
- Option 1: Move the build plate up and secure it with zip ties to prevent it from falling during motor removal.
- Option 2: Remove the build plate entirely. Detailed instructions for this procedure are available in the bed replacement guide.
- Disconnect the target motor from the wires. Unplug the motor connector from the motor.
- Unscrew the motor bolts. Unscrew three of the four bolts first.
- Unscrew the last bolt carefully. Be prepared for the motor to move down once the last bolt is removed.
-
Remove the motor from its position. Carefully move the motor straight down. Let it rotate if needed.
- For the front motors, you can move the printer to the edge of the table so that it rests on three legs.
- For the rear motor, you'll need to place something under the printer (like wooden blocks) and move it to the edge of the table so you can access the motor while the printer rests on two legs and the support.
- Prepare the new motor. Remove packaging and check for any damage.
- Push the motor screw into the bottom hole and screw it into the bronze nut.
- Orient the motor connector. For front motors, orient the connectors towards the back. For the rear motor, orient the connector towards the left back printer door where the mainboard is located.
- Screw in the four mounting bolts but leave them loose (finger-tight).
- Set the build plate. If you removed the bed, reinstall it. If you used zip ties, remove them now.
- Lower the bed to the very bottom using manual rotation or the Web Interface if powered on.
- Tighten all accessible motor bolts.
- Move the bed up enough to access the remaining bolts and tighten them.
- Connect the motor wires. Plug the motor wire connector into the motor socket.
-
Move the printer to its permanent location.
-
Power on the printer.
- Run the bed leveling procedure to ensure proper calibration. The adjustment procedure for Z-motors is described separately in the Z-motor alignment guide.
