Mach3 issue?
« on: January 29, 2019, 12:02:54 AM »
(Edit to add update ******) So I did some more testing and test cutting last night. At this point I think I have completely ruled out Mach 3 or any sort of software/g-code issues. I made a pattern that had a very long narrow t-bone fillet so that I could actually watch the DRO as the bit went into the t-bone fillet and come back out. I could see that the axis had no movement on the DRO but you can see that when the bit exits the fillet and fully engages the material there is drift present.

sounds like your steppers are gaining or losing steps and therefore departing from the tool path you have
programmed. Doing any useful machining when the axes drift off on their own is hopeless.

You are going to have to tune your motors such that they stay 'in the groove'.
