Replace the Z-min switch PCB

1

Flip the V-One

Unplug the V-One from power and carefully flip it upside down ensuring the carriage and bridge are well supported while flipping so they don’t slide around.

2

Remove the Base Cover

Undo the 4 hex screws from the base using a 2.5 mm hex key and remove the base cover.

3

Locate the Z-min switch PCB

In this orientation, you'll find the Z-min switch PCB in the bottom left corner of the main control board.

4

Replace Z-min switch PCB

Using a 2.5mm hex key, unscrew the PCB from the threaded spacers. If your unit had thin Kapton washers they can be disposed of as they’re not longer needed with the replacement PCBs. Then install the new Z-min switch PCB with the same screws.

5

Close up the V-One

Put the base cover back on with all 4 screws. Be carful to support the bridge and carriage while turning the V-One back right-side up.

6

Test the new switch

Plug your V-One back into power and connect the USB to your computer. Power on the V-One and open the software. Once the software has loaded, open the console using the ~ key or by pressing alt + c and enter the command M601 S1 . This will let the V-One know it has a new switch.

Reboot the V-One for the switch change to take effect. You can leave the console and software open while rebooting. Once the printer is connected again, manually test the Z-min switch by pressing it with your finger or a pen.

In the console you should see the z-min switch show as TRIGGERED when pressed and open when released.

Repair Complete!

Congratulations, you have successfully swapped the Z-min switch on your V-One!
