Hi
The jpg's CV50Accel1 above was with Z being different Acceleration to X/Y and was CV100 mislabeled , the other that looks good was CV50 the same Acceleration.
The letting example is 2mm high, it was very good with CV and Mach3, and in Simulation looks good with CV100 on all 180 angles.
As CV100 is in my examples 25% less time and that it simulates quite well it should be good for ant Lettering, 2.5D and 3D machining.
Regards,
Mauri.
