I've got this thing totally screwed up. I should be doing a 15 hr cut. I am 26 hrs in and maybe 5% done. I'm running with an error, PWV or somthing like that. It's a pully speed error. It has set the machine down to run on it's most minimum setting. It seems like it is cutting out the design correctly, but the rate it's going will take a couple weeks or more!!! Messing with the motor tuning on the 4 axis in Mach 3 maybe made it even worse, I don't know. If anyone can help me with the Mach setting for this set up, I'd sure appreciate it!
