Further testing...

Mach is completely unaware of any limit switch. It doesn't show at all on the diagnostics page.

The upper plexi glass door estop switch does nothing. The mushroom estop also does nothing.

The X and Y limit switch are odd also.. I have a X+ limit, x- limit and Y+ & Y -.

If I'm jogging Y+, and trigger the Y+ limit it stops. If i trigger any of the other 3 limits while jogging Y+ it wont stop. I thought they were all tied together, and it was to stupid to know the difference but apparently it does, hence why usually it homes one axis at a time on my other machine.

I checked for voltage (ac or DC) at the estop, and found nothing.

Now im officially stuck. haha

Ripped into it pretty good. all panels off, checked all fuses, uses a pair of angled pliers to do a light pull test on all wires. Everything was tight and no loose connections. I found a couple of the stand offs that hold the boards loose, and tightened those. Didn't notice any chaffed or burned wires. I did notice all the motor wires pass right next to the big transformers at the bottom of the case (noise?). Another thing i noticed was on one of the drivers (top driver) the "B" phase B- and B+ phase wire were backwards from all the rest of the drivers... I don't know if that was on purpose or a mistake.

I also traced the E stop mushroom buttom wires back, along with the micro switch for the plexiglass door back. They are tied in together at the BOB. They are connected, so i don't know why they wouldn't work.

Hmm...

Well more info.. Figured i should test the big red estop button on the machine. While mach was open and active, i jogged to confirm it was live. I then hit the estop button, and mach did not see any error. I then jogged the machine while the red estop mushroom button was fully depressed...

The only real way of stopping this is flipping the breaker, or pressing "reset" inside mach 3. I sure aint going to reach around the machine to flip the switch on the side if it is freaking out.

Also, under my diagnostics page, my M1++ and M1-- limit LED is illuminated even without the machine on? When the machine turns on, lights remain on.

Funny business.

Ok so here is my .XML

I fired up mach, then turned on mill, waited a few seconds and clicked the red reset button. Went to jog X axis and y axis moved at the same time!!! After 20 seconds, they then moved independent of eachother.

This thing has a mind of its own haha..

Thanks guys.

Until then ill be up all night trying to research what is going on.

Thanks!
