I have a CNC milling/engraving machine that I built, and just added limit (home) switches. The CNC commander has been working fine, but now homing seems to be an issue. All of the switches function correctly and I see them in the status section of the main window. X & Y work perfectly, but Z is acting strangely. It heads towards the limit switch (I have the directions all set correctly), but does it in two very short attempts and does not get there. It only moves a couple of mm at a time. After that the X & Y axes move as they should (simultaneously, although I have the order set to Z , X , Y). If I repeat the homing sequence, and it reaches the z-axis switch, it alarms out and stops. Any ideas on why this would be happening?
