Yvan256:
My Roland MDX-3 needs to be repaired (again), I need to rebuild the Z-axis with a new metal bracket and bronze bushings, the original design is so weak that I'm shocked it lasted this long (i.e. for the right rod, there was a single bronze bushing at the top, an HDPE hole at the bottom and three small HDPE fingers for the left rod).

Sorry to hear Yvan, things where coming along nicely.

Do you source regular bronze sleeves for your bushings, or do you use oil impregnated bronze like Oilite?

I think the MDX-3 has regular bronze sleeves like printers and scanners, so I'm trying to find the same thing from old printers, scanners, CD-ROM and floppy drives, however 6mm rods aren't exactly a popular design choice for these devices.

Yvan256:
Just a small update, the MDX-3 is "kinda fixed", I got 6mm bronze bushings from China and I hot-glued one in place for the time being. The plan is to use the MDX-3 to cut a new Z-axis assembly for itself, I also plan on making that assembly compatible with the Black & Decker RTX mount I already have. It will offset the work area of the MDX-3 but I should be able to work around that easily enough.
