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 repair 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.
