My new printer design is almost finished. X Y and Z all run smoothly, as does the extruder and hot end. Bed leveling mounts are next. Then z end stop. Still need to grab the SSR from @Joe_Spanier to get the bed heating. Then the enclosure.
I’ll post video links in the comments
Specs:
Ramps 1.4 with sd8825 drivers
Marlin, simplify3d
12" DC silicon heater
E3d v5
Roton trapezoidal z rod
10mm smooth rods all around
Frame is bolted together, no plastic connectors. Most extrusions are 20x40, some 20x20. (Misumi)
Mk10 extruder customized for 608zz bearing plus modded a few bits
3 point leveling
Z axis moving. Z axis test: https://youtu.be/LvYuvqebogo
X and Y moving. Printer test x and y: https://youtu.be/NXBTbkfQV0Y
Ignore the wobble in y axis motors. I tightened things after taking the video
250 mm/sec test of xyz and extruder. All running smooth. (Ignore the uneven floor and background noise from another printer). 250mm/sec test: https://youtu.be/qV3Z4AyL5jA
Are those IGUS RJMP bushings?
AFAIK they require mounting in a housing to get the correct fit on the rods, how are they working for you?
I use RJ4JP instead as they have correct fit without mounting in a housing.

They are the j plastic bearings from Lulzbot
Do they fit your rods without any play? Lulzbot prints press fit housings for then
Fits great. No play. Very mooth
