Problem with Z-Axis Reversal when Soft Limits Active
« on: July 09, 2016, 06:37:16 PM »
I am using Mach4 with ESS and a Leadshine MX4660 driver.  I have got xyz axis's set up with hall detectors and when I reference all or any individuale axis they home properly each time.  Yet when I activate the Soft Limits button the directions of X-axis and Y-axis work fine but the Z-axis reverses direction when I press a plus or minus jog button.  Can some one explained to me what I have done wrong to have the Z-axis reverse movement directions when the Soft Limit button is active.

Need to correct my problem statement the z-axis only goes in up ward direction when soft-limits is active!
No matter if i push the plus or minus button it always goes positive or up ward.

Sorry just wanted to make sure i have this right.

This is a quirk of how the soft limits react if the setup has some values in the wrong place.
