SmoothStepper USB / Re: Homing "x" axis not working correctly

« on: June 20, 2009, 06:04:12 PM »

I'm with ya, Don! There HAS to be something here that causes this. Mine now won't back off the Z no matter what I do. The servo doesn't move, the handle doesn't move, nothing. X and Y back off just wonderfully, Z hits the switch and that's it, no backing off. I ain't buyin' the NOISE thing either. Noise doesn't seem to me to want to cause ONE thing over and over. Noise would be doing something else also.

I'll be looking forward to replies from others to see if there's some file or something that we can replace, change, delete and recreate, something, to fix stuff. I'm totally mystified by mine and have changed my homing to do Y then X, then Z, where it zeros the axis and sets it to homed, but won't back off the switch, giving a limit switch message after the overriding ends!!

Like I said, I've tried everything, 0, 10, 100, 200, 300, 500, 1000. I'd be happy to try something else!!

OK, I'll try that.

One thing I KNOW is there is a physical LED on the C16 and a physical LED on Pin 13 on the BOB, and both of those are ON when this happens, as well as the yellow LED's in Mach on the diagnostics page for M3 Limits and Home. So the signal from the opto switch is making it to the BOB at least far enough to trigger it's LED indicator and trigger Mach enough to show its LED's!! Seems to me Mach either isn't over riding the switches, or not backing Z off the switch, which is what I SEEM to be seeing, the handwheel on Z does NOT backup a bit like X and Y do when homing and I swear it used to back up! How can it come off the switch if it doesn't back up?

Switch setup is CNC4PC C16. They are optical and are apparently connected in series. There is a wire going from the C16 X Home to CNC4PC C23 BOB Pin 11, another from Y Home to Pin 12, another from Z Home to Pin 13. Ports and Pins setup accordingly. This was working the other day just fine.

I've put values in SS config for home switches from 0 to 1000, like 0, 2, 10, 100, 200, 300, 500, 1000, with no effect. Should I try something else?

Hey Hood,

Get this. After working for several days, now the Z goes to home, stops and doesn't go up off the switch, so I have a limit engaged message. It seems as if it's either not overriding the switch, or it isn't backing off the switch. The servo motor does NOT backup in Z like it does in X/Y. In X/Y it hits the switch and backs up a little, in Z, it hits the switch, the motor doesn't reverse even a tiny bit, and I get the limit on message and the LED's are on on the diagnostic page. What might that be? Granted, the knee is heavy but counterbalanced with 2 200 Lb. gas springs, so it moves pretty easily. I'm mystified again!

That fixed it! I was being safe and had my soft limits .1" off the switch. Somehow yesterday I must have had soft limits off and it worked then I somewhere along the line turned 'em back on and it wouldn't work. I never connected the two. Senior moment!

Homing works great now.

Thanks, Hood! No wonder you have 6900 posts, you're the MAN! Saving us retired guys from ourselves over and over.

Reinstalled over the top, didn't fix anything, but...........get this, turn Soft Limits off it works just fine!!

So, what's that about? I'd prefer to leave soft limits ON always, so I don't forget. I do get a beep and a Soft Limit exceed or something when homing just after the Z hits the switch. No idea how Soft limits being on makes it NOT run the move code, but carry on and home Y and X.

I'll have to check numbers in soft limits and see if there's something obvious.

Is there VB code to turn soft limits OFF at the beginning of the routine and ON again at the end!!? Do you have Soft Limits On?

The mystery continues.

I tried X, it won't move in the button script either.

I MDI'd G53F20G1Z-2. and that worked, so it's NOT G53!!

What version of Mach is best to use? I have latest lockdown. Should I try another, or just try and install over the top? I guess over the top first, then maybe something else.

Pretty strange that this worked fine yesterday. And it was while trying to tweak SS config for noise and having SS firmware not unload a couple times. When that happens you have to unplug the SS and the settings you did are NOT there, you need to do them over. I've learned that if I want to tweak SS, I quit Mach, restart, tweak SS, quit mach and watch for the green light to go out, then carry on. That SS could use a touch up, software/firmware wise, methinks!

Might I have a corrupt XML file, even tho' everything else seems to work? Or if I get a corrupt XML will other stuff be messed up? I had a bad XML last week trying to configure the Charge Pump on my C23. I'd set it, the numbers would move to a different field in Ports&Pins. Arturo from CNC4PC said I might have a corrupt XML, sure enough, that was it. Everything else seemed to be working.

Yup, message box pops up, click OK, next message box pops up, finishes homing Y and X. Z does NOT move.

That's even stranger! Same code runs for you. So what's making Z not move?

I'll try X, see what happens. Maybe it's something with Z and the home switch and SS noise settings.
