last week I finished re-assembling my 1000x1000 X-Carve and did some test cut today.
I'll try to explain the better as I can: I have cutted a guitar neck template profile and all seem to be accurate except for the lenght. The template should be long 665,4/5mm but it's actually 664,4/5mm.
While I have re-assembled the machine I checked the wasteboard squareness (it wasn't square before) and now seem to be accurate 135.4/5mm in both diagonal.
I also re-done all the wiring, and re-checked the V-Wheels and Eccentric nut. Made the 30 minutes X axis stiffening.
Calibrated the stepper: Now on a 600mm line I have 599,99mm.
But I still can't figure how those template are always a mm short than they should be. Also cutting a square, seem to be not exact square and not about the correct dimension!
Any thoughts or tips? Could the X axis be not perpendicular to the Y axis? I found that pic "stolen" from @AlanDavis while seems that he had an X to Y axis square problem too (if is my case).
I'm near to have the machine working like I want/need and this is so frustrating!
Thanks in advance!
