Well, it still goes off of the original tool path, and in all axes. The acc is now 120 and it still happens. The average feed rate I use is 1000mm/min, if the spindle doesn't tolerate that much, i use even smaller feed rate.
What can be the problem? The drivers and the motors are most likely okay, because I don't believe that all three went wrong at the same time.
Psu?
Or another idea: aspire generates so accurate toolpaths, that mach3 just goes mad about those small coordinates. As is said, my machine can go 0.02 mm on x and y, and 0.01 mm on z. Still goes off all the axes.
In aspire, I set the tolerance to 0,02 from 0.01 and it still happens.
What can be the problem?
One thing is sure. All the axes, when they move off of their path, move in their positive direction more, than in the negative.
I had some unregular carving code today, that went great for 20 minutes and in the last 2 minutes it has gone upwards 5 millimeters.
