Homing and move off of switches.......?
« on: May 15, 2010, 12:28:27 PM »
Hi folks,

Quick question. The issue may or may not be with Mach3. (version download / installed May 2010 running in WinXP SP2).

When I press the Ref All button, all 3 axis move to their respective home position and move off the switch a small amount. The Z axis moves enough to reverse state of the M3Home switch (LED is off on the diagnostics screen). The X and Y LED's are still active even though a slight move occurred off the limit switch. If I jog further in both X & Y the LED's will change state. Soft Limits is engaged and working.

I will say that the distance moved off the switch in Z is greater than the distance moved off the X & Y switches.

Everything else in Mach3 seems to work regardless of this issue, just something that bothers me. Is there a setting that I / OEM missed to setup?

Any thoughts or suggestions.

Thanks,
John

You may be seeing noise. You can try increasing the debounce setting in General Config. Try 2000-3000.

Also, try homing at a lower speed.

I checked the settings on the machine and there are 2 fields - "Debounce Interval" and "Index Debounce" both with a value of 10.

What value in which field???

Debounce Interval. Try 2000.
