The Z-axis screw is responsible for the platform’s vertical motion. It is driven by a stepper motor placed under the bottom plate. In order to allow smooth movement of the platform, the Z-axis screw should be lubricated every 400 working hours. This manual shows how to properly lubricate the Z-axis screw.

The following manual shows the M200 Plus maintenance work. For the M300 Plus, these procedures are the same.

Spool Holder Removal

Remove the spool holder from the rear side of the printer.


Lubricating the Z-Axis Screw

Apply a small amount of service grease on the Z-axis screw. You can use a screwdriver for that purpose.


Spreading the Grease

In order to spread the grease on the screw, move the platform up and down several times.

Use the options from the menu: Tools -> Platform -> Move Platform.

Repeat steps 2 and 3 for better Z-axis screw lubrication.


Spool Holder Assembly

Attach the spool holder together with the spool to the back of the printer.
