Tested machine for repeatability and backless almost 0.5uM for all tests Great!!!
But still not getting round circle accuracy withing 10uM with Mach3 G2 G3 modes!!!
Every time X-axis reading gets 80~100uM higher then Y-axis.
assumed there should be some mechanical error but nothing is there checked all bearing pre-load and backless.
Lot of frustrated wat to do!!
tried all servo tuning wizard with different gain setting but not getting at least X-Y Result perfect in circle @90 degrees!!
if it gets X-Y 90 degree result right then only I'll be able to check random angle for diameter!!!
trying hard for constant circle diameter value within 10uM!!
