Hi All,
I've had my IH CNC conversion kit in place for about 6 months now, and have noticed a problem. I'm wondering if anyone else has had this issue.
I originally had all three axes set to 100 in/min and an Acceleration setting of 10 in^2/min. I use Mach 3 as the controlling software. After homing and then GoTo Z (say G55 with X=10, Y=4, Z=10) if I hit a GotoZ a second time, the machine would start to go to machine Zed in the Z direction (Safe Z moves set to Machine Zero) before it's return to G55 zero, but would halt in the midst of the Z-Axis move after an inch or so and then do this "clicking". The seever would sort of stutter. It worked fine in every other fashion but not here) At this point, all reference was gone, and the only recourse was to Home again.
After messing with this for some time (changing many things along the way), I finally discovered that if I turned down the the speed to 75"/min, the machine seemed to operate as desired. I have left the Z Accelleration derated to 7.5 as well. X & Y seem to be just fine at 100 and 10.
Has anyone else experienced a similar problem. What settings for Speed and Accel are you folks using???
Thanks for your replies.
David
