General Mach Discussion / Re: Y axis move when just X axis is homed
« on: December 25, 2010, 09:32:22 PM »
Merry Christmas everyone....
Spent a couple fooling with the mill today ...
I have the soft limit enabling again. Not sure how but with all the switching around or something I must have changed my limits on the Z axis. I found I had it set to be 0 to 6 instead of 0 to -6.
Still not totally happy as for some reason once I got the soft limits to enable I found that homing all causes the X and Y to work as expected but the Z axis seems to obey the slow down near the extremes set in the soft limits even when homing...this would not be all bad except as it sneaks up on the zero position (up) it gets slower and slower then just before it trips the switch the soft limit is exceed (as zero is just in front of the switch) and this causes Z to be non referenced. My work around was to actually spec the soft Z max limit as .05 instead of 0.0 this allows the Z to actually hit the switch before the soft limit and thus it is referenced. I think there might be a slight bug that fails to turn off the soft limiting when refing the Z. X and Y do not exhibit this behavior.
