Hi,
I have connected all limit switches in series with e-stop. I have Automatic overide on and when I hit a limit, I cannot jog off the limit.
I have all limits energizing a relay back at the control. (G540) then locally wiring into e-stop. The limits are working and dropping the relays. I have no noise issues. I never get an e-stop until I hit my E-stop button or limit switches.
Any ideas?
I am still using trial Mach3. Is this the issue? I plan on buying Mach3 once I figure I can get everything working on my machine.
Thanks,
Bob

As I understand it, if I have automatic overide on when I hit a limit switch all I have to do is hit reset and jog off, but it doesn't work.

Does the Reset stay off or does it come back on again when you try to Jog off?

Do you literally have limits and E-Stop connected together? If so, this is unnecessary at best, and undesirable at worst. Mach will stop *all* axes as soon as *any* limit is triggered. Once you trigger a limit, can you get Mach out of E-Stop? If not, you won't be able to jog off the limit. The series-connected limit switches should be connected to an input, and that input should be configured in Config->Ports&Pins for ALL limits.

OK, I'll try that.
When it hits limit I can't get it off E-stop condition, obviously because the e-stop is triggered. I hear alot of guys saying they are using limits with e-stop so I wired it that way. I have a G540 so I only have 4 inputs. I guess I will use one of them now.
I'm going to rewire it and see.
Thanks,
