Hi guys,

I was asked to cut some holes for a bakery display unit to hold cup cakes and make a rectangle release cut then some without the holes for underneath. I was disgusted to find (after making 20 of them!) that they came out as parallelograms! Thankfully fixable on the table saw and the holes were not too misaligned that you would notice but I obviously have some problem.

My guess would be a slight error on the motor tuning in mach3.

Has anyone had a similar problem before that could shed some light on it please?

When I calibrated my motors I used the manual method of telling it to cut 100mm then calculating from the actual cut length. I suspect that there may be a better way to do this.

Any help would be greatly appreciated!

Thanks,

KC
