Shift in my X Y and Z axis
I am running an ACT desktop milling machine / mach 3 processor with Mach 3 CNC v 3.042.040 on a 2.83 GHz quad core processor and windows XP with a lot of services disabled as suggested by ArtSoft. The problem is the axis will shift during a machining operation. I will set the machine up to run a ¼ inch end mill at 5 in/min cutting wax, run it and measure, no problems. Set the machine up with a 1/8 end mill at 5 in/min for detail cuts, run it and measure, stars out accurate but ends up off in the x by .053in, y by .042in and z by .027in at the end. The results are never the same and is not repeatable. I have slowed my feed rate, ran a ground wire from the cnc to the computer frame and even reinstalled XP and Mach3 CNC with no luck. I have had the x axis jump during a jog. If anybody has any ideas I am desperate, so tired of cutting the same thing over and over.
Thanks
Jon
