Introduction

This guide serves as a prerequisite guide for replacing the z axis motor, the motors and ports. It shows how to remove the frame so these parts can be replaced.

Step 1

Removing the frame is necessary to access the z axis belt, motors and ports. Make sure the unit is unplugged and set on a hard level surface.

Step 2

Pull the x-rods away from the plastic sliders on the y-rods, and flip the slider upwards to release the tracks. Lift the extruder assembly out of the way.

I could get it loose on one side. The other is firmly stuck. It does let me flip the head up to the side, but it won’t come loose without significant violence.

Also, to the the first one loose, I have to pull the Y-rods so hard that they bend. Not plastic deformation, they are not ruined (I think) but the amount of force disturbs me.

Step 3

No tools are required to remove the frame. Press down on the printing bed with your thumbs while lifting the frame with your fingers. The frame easily slides up.

This doesn’t work at all on my M3D. I had to force in a tool, a kitchen knife, to crack it open in each corner. THEN I can lift it up. (But I still can’t lift it off since I can’t remove the printer head. More force needed there.)

Reassembly is harder, because you have six rods that must get into separate holes more or less simultaneously, and I guess those small metal rings on the top have a purpose too.
