Title: Problem Using Mach3
Post by: Fred583 on July 16, 2015, 01:10:21 AM

I have a 6040 and am using Mach3. I have a random/intermittent problem which I hope others might be able to help with.

Sometimes when I try to traverse using X/Y controls Mach3 hits estop, I have to reset and continue. This sometimes happens whilst executing reference all axes. However once set up I can run a long gcode job without issue. So strangely this seems to be an issue involving short duration motor feeds.

Seems a bit odd so I'm not sure where to start looking.

Hi Fred,

This type of problem is generally associated with the pickup of electrical noise on inputs wiring.
Try increasing the Debounce Interval to 2000 or so (Config / General Config page). If this improves the situation then check that all your inputs wiring (e-stop, limit, home, switches etc.) are properly screened and earthed.

Actually I think you hit the nail on the thumb. This was a random problem and after I moved some of the equipment around physically it went away.

Thanks.

I am pleased you managed to get it sorted.
