I’m sarted to assemble my 23.5mm MPCNC, most of the parts I printed end of last year on a new Ender3 pro. When I measured the squareness of the assembly it"s almost 1° out. So I tried to toy around a bit with the tension bolts A;B & C with no success.
I have meanwhile also build another 25mm MPCNC in my other home without any issues regarding squareness, those parts I printed with an MP3DP. So I have something to compare.
As I did not really realized what is causing the issue, I started to check the XYZ-BURLY, and look there, it seems I found the culprit. The Z-axis seems also to move harder than on my other build, no wonder if the XYZ-BURLY squeeze it more than it should.
At the moment I just plan on using it anyway. Question is, could it make sense to put some shims where the XY-BURLY is bolted to the XYZ-BURLY’ 4 points?
I brought the same board from my other home, so I plan to run it on dual Endstops, but to square it with the stepper will need to much force in my opinion causing more troubles than doing good.
Any opinions on that matter?
