UNSOLVED stall recovery?

tenaja

Is there a way to recover from a stall, for instance, continue where the stall was first detected, at a reduced speed? I understand the position of the stalled axis will be inaccurate, but in some instances, it will be close enough.

I see Resume print after power failure, but not a Resume after stall.

I also see a way to run rehome.g, but I would like to control which program is run. Is there a way to do that?

Also, I will need to resume without re-homing. The action of homing will mess up my "print"--this is not a printer application. Or, would the way to do it be to issue a "reduce speed" command?

In my rehome.g file, I have this:

; rehome.g
; This file is executed if a stalled motor is detected.
M220 S40		; continue at 40% speed
M300			; send a beep (if connected to web)

Is it going to stop all moving axes, and run this file, then reset?

Right now, I am not detecting any stalls under any circumstance, so I've got to get that sorted out, too...I will work on it in another thread.

Thanks!

have you seen this?

specifically the R value can allow you to run a rehoming procedure before continuing.
Or you could have it pause which would save the current position

nevermind, just saw your other post

@jay_s_uk
Thanks for trying to help... as you can see, I think I need to sort out the stall detection before I get on to stall handling.
