Hi,
I've done some searching, and mostly come up short here... hopefully this hasn't been beaten to death already.
I'm running Mach3 R 2.63 on a dedicated WinXP machine, and an AccuCut XP series router from Computerized Cutters. The machine uses steppers. Z axis is ball-screw, the others are rack and pinion, and it's pushing a 5hp Perske spindle.
I'm cutting 28 sets of lettering into a 2x4 piece of acrylic, and each set becomes progessively deeper. There are 8 letters in each cut, so 8x28=224 movements up and down. Initial cut height is .01, and by the end I'm probably cutting closer to .04 or .05.
I can only guess this is a lost steps issue? I've brought my Z speed down to 20, acceleration is at 4 in/sec2.
I verified the G Code and every cut has a Z of .0100.
The manufacturer is closed until Monday, so any help would be greatly appreciated!!
Cheers,
Dave
