ALT-S (STOP) Causes Mach3 to go into Reset Mode
« on: September 27, 2011, 10:43:29 PM »
I do not see this on my stepper based system so I think it's something to do with my Servo setup.

I'm running a PMDX126 board, G320 drives, and KelingInc Servos.  When I have G-Code running and I press the STOP button,
it automatically puts Mach3 into Flashing Reset Mode.  I click on reset and I can go again but I do not think this should be the case and I sure think I could loose my work positions.

Any idea what might be happening?

THanks,
Richard

I've never used servos, but your probably faulting the drives which is putting Mach3 into E-Stop.

You should always pause and wait for motion to stop before hitting Stop. Stop will almost always cause a loss of position.

Feedhold, wait for everthing to quit moving, then press Stop?

Thanks,
Richard

Yes, that's the proper way to do it. When using Stop, there's no deceleration, so position is almost always lost, unless there's no motion.

That works great.  I guess the stepper based system doesn't have the encoder feedback so it's not as sensitive as the G320s.
What was nice about stop, and cycle start is it also controlled the spindle where as feed hold does not.

With your stepper system, you were most likely losing position everytime you used Stop.

Not sure what your macro is doing but may be a problem calling a macro from a macro.
Anyway this should work if all you are wanting to do is feedhold then stop then move to z.2

Not sure what you're trying to do either but...

Code: [Select]
While IsMoving ( )
code " g4 p 1 "
Wend

is going to KILL the system in very short time. It's effectively saying to Mach - the busier you are, the more I'm going to give you to do. i.e. an infinite loop constantly adding more to Mach's gcode buffer.
