Assembling my unit and have run into what I think is an issue…
I slid the X/Z assembly onto the extrusion rail. In between the two black top slide rollers are two aluminum belt pulleys. One is about 1/8" above the rail but the other is slightly dragging the rail.
Does not seem right to me as the belt pulley will drag on the rail as the assembly moves back and forth. Also,
in the next step I have to slide the drive belt under the pulley. This would work under one pulley but no way is it going to slide under the other pulley. A pic is attached that will hopefully show the issue.
Ideally all the holes would be perfectly positioned, and everything about the machines would be “just so” — unfortunately, the machines are made to a tolerance which allows their price point, and occasionally multiple things go wrong so as to cause difficulties such as this — if clearing out the powder coat doesn’t address this, use a small round file to slightly increase the size of the hole at the top as much as is needed to address the problem.
