I ran into the same thing with the belt rubbing and made some clips to offset the belt:
You might also want to check if each wheel is parallel to the other wheel on the same side. There is a brace I made above to adjust them parallel since the plate seems to flex under load. I eventually also had to route a groove for the wheels to run in so the carriage doesn’t migrate over to one side of the table.May 23, 2019 at 8:54 am #101359
I am not understanding how or why your belts are rubbing? Using my belt holders? Can you get some pictures of them and maybe the Y stepper assembly.May 23, 2019 at 9:38 am #101364
I already use your clips.
but using a clip, the belt will look like a ‘W’May 23, 2019 at 9:48 am #101365

In regard to the belts touching the z tubes: An obvious question is are you positive the sides are straight and without any bow? And are both sides parallel to each other?May 26, 2019 at 1:38 am #101670
In regard to the belts touching the z tubes: An obvious question is are you positive the sides are straight and without any bow? And are both sides parallel to each other?I used a steel ruler to check if there was any bowing, but I couldn’t find any bowAnd it was parallel (within 0.5mm).But the wheels weren’t quite parallel.(Maybe it’s because there is no wheel spacer.)May 26, 2019 at 1:44 am #101671May 26, 2019 at 10:13 am #101695
What sized idlers did you use?May 26, 2019 at 10:15 am #101696
Are the M5 nuts hitting the top, flip them over if they are.May 26, 2019 at 11:01 am #101704
I use 20t idlers(diameter is 12.3 mm.) and M5 nut doesn’t hit the top.
