**RESOLVED** M92 Not Working

[Riley]

There were at least four places where you would need to change that input number. Go through the m92 again slowly and double check. It worked for me....took a couple weeks to figure out what the issue was. As soon as I changed my m92 the darn thing worked!

[please no smoke]

I just wasted another two hours of my life working on it. I changed the 4 11's to 7's and since my estop is wired like the original drawing (active low) I switched the three < and > signs. Still nothing. I have +5v going into my common connection (in 8) for my estop. This appears to be different in more recent ajax prints. Should I completely rewire my estop? Does it only work on high active?????

Thanks

I rewired the estop so that the common is now ground (like the newer drawings). When I put 5v to input 7 nothing happens. How do I make mach recognize that input 7 is estop? I am thinking that somewhere mach is told that in 11 is estop and cannot be changed by the user. Maybe I should just rip it all out and use 11?????????

Alright I apparently got the ports and pins setting right for the estop now. I think the estop button never interfaced with mach and I never had a clue since there is an old redundant electro mechanical estop as well. Now the estop works and the m92 works on the z. It is rolling right past the x, and y limits, but I will tear into that tomorrow. Thanks Riley!

Ok. My limits work fine, then I hit M92P1 and the x moves in the negative direction and onto hard stop. After that the limits don't work until I restart. Shouldn't it move positive.

[Riley]

If you turn the x axis by hand so that the servo motor is being spun clockwise which way do your dro's go?

[please no smoke]

DRO's are correct in all operations. Just the M92 moves in the wrong direction. I did have to swap polarity on x and z axis to get them to move in the correct direction.

[Riley]

Are you using the axis reversal check box in mach? I'm just curious...thats what I had to do.

[please no smoke]

I believe I am for the y axis only. The other two I reversed the motor wires. I wonder if there is a problem there? I wish Scott would check back in.

It was that stupid M92 macro. On the two operations where it was looking for the limits I changed the <, and > around. Works not. Heck, I just ran my first program. Closer each month. Should be fully functional in about 20 years.
