I have an Eldorado with the full CNC package but not with the ball screws.
I am using Mach3 and trying to set up the motor tuning values.
I have them dialed in pretty close, X and Y are at 40,000 and Z is at 60,000.
I reset the DRO put in a basic G-Code movement (g01z.1) and the machine moved to the location. The mach 3 display shows a move of .1 but the DRO shows a move of .0923.
I do this over and over and every time I get a different number. same thing happens with the X and the Y. .0923, .0922, .0898, .0998 etc.
I am not sure if the backlash has anything to do with this because I am always running them in the same direction so the back lash should have no effect.
Any ideas?
