Title: Limits problem
Post by: cropwell on March 15, 2016, 08:45:32 PM
I don't know if anyone can offer any advice, but all of a sudden and for no apparent reason (?) my limits were all triggered and would not reset. All ++ are on one circuit and all -- are on another. I also have a limits override switch. No matter how Mach3 was set up one or t'other of the limits was triggered. I use a second BoB on LPT2 and was beginning to suspect the BoB, cable or port card as everything looked hunky dory on the meter.
So I changed the BoB and cable, but no joy - everything was the same.

On an off chance I looked at all the other input pins and down the list, all the jog inputs were set as active on port 0.

I de-activated them and the limits now behave as they should.

Anybody know why ?
