Z-Probe Servo
Z-Probe Servo
This guide covers how to replace the Z-Probe wires on the Vision Miner 22 IDEX V4. The Z-Probe and its dock are mounted on Tool 0 (T0). The probe attaches to the Z-Probe dock via magnets. If the Z-Probe has failed and needs wire replacement, we recommend ordering a complete replacement probe with pre-installed wires. However, if you need to replace the wires yourself, follow this procedure.
Info: IMPORTANT: This procedure applies only to Tool 0 (T0). The signal cable on Tool 1 (T1) does not need to be replaced.
Safety and Warnings
Warning: WARNING: Turn off the printer and unplug it from the power outlet. Make sure the printer is completely powered off before starting any work. WARNING: Wait at least 60 seconds after powering off for the capacitors to discharge. WARNING: The nozzle and heater block may still be hot after a recent print. Let them cool to room temperature before touching. WARNING: Support the terminal block holder from behind when pressing connector release tabs. Pressing without counter-support can bend or break the holder.
Tools and Materials
- 2 mm Hex screwdriver (hex wrench)
- Replacement Z-Probe wires (white and black silicone wires)
Overview
The Z-Probe wiring consists of three connections:
| Connection | Wire Color | Location |
|---|---|---|
| Z-Probe dock magnets | White and Black (O-shaped) | Inside the Z-Probe dock on T0 |
| Signal cable to T0 toolhead | White | Screwed to the Tool 0 hotend; connects with the white Z-Probe wire |
| Terminal block wires | White and Black (silicone) | Terminal block above the extruder |
Removing the Z-Probe Dock Wires
-
Locate the Z-Probe dock on Tool 0. The probe attaches to the dock via magnets.
-
Using a 2 mm hex screwdriver, unscrew the two screws securing the magnets to the Z-Probe dock.
-
Remove the magnets. Behind them you will find O-shaped cables � one white and one black wire.
-
Carefully pull out the two U-shaped cables (white and black) from the dock.
Removing the Signal Cable from Tool 0
-
Locate the signal cable (white) attached to the Tool 0 body. It is secured with a screw.
-
Using a 2 mm hex screwdriver, unscrew and remove the signal cable from the Tool 0 body.
Removing Wires from the Terminal Block
-
Locate the terminal block above the extruder on Tool 0. The Z-Probe uses the white and black silicone wires in this block.
-
Using a 2 mm hex screwdriver, press the release tab on the terminal block to release each wire. Hold the terminal block holder from behind while pressing to prevent bending it.
Warning: IMPORTANT: Always support the terminal block holder from behind when pressing the release tabs. Pressing without counter-support can bend or break the holder.
- Pull out the white and black silicone wires from the terminal block.
Installing the New Wires
-
Place the new O-shaped cables (white and black) into the Z-Probe dock.
-
Place the magnets back into position over the O-shaped cables and secure them with the two screws using a 2 mm hex screwdriver.
-
Attach the new signal cable (white) to the Tool 0 body and secure it with the screw using a 2 mm hex screwdriver.
-
Route the wires to the terminal block. Insert the new white and black silicone wires into the terminal block.
Warning: IMPORTANT: After connecting, pull the cables taut so they do not sag or rub against the belt. The wires must be neatly routed, must not contact any moving parts, and must not hang low enough to interfere with the probe docking into the probe dock.
- Reattach the Z-Probe to the dock and verify it snaps onto the magnets correctly.
Verification
- Power on the printer and run the Z - Probe Test macro from the dashboard to confirm the probe is working correctly. See the Z-Probe Troubleshooting Guide for details on interpreting the test results.
