Z motor stalled on "long" retracts

p8blr

@phaedrux Here's a longer video:

http://youtu.be/-me69PnPpg0

Yes I can move Z independently and it does not stall, it requires both of those lines together for it to happen.

I am not using z hop.

Maybe a firmware bug?

Thanks.

Phaedrux

Thanks for the video, it does show it a lot better. Very strange.

Can you capture and post the results of M122 and M122 B20 after you've caused the problem to happen?

Can you also try adding a G4 S4 near the start of your config.g?

Couple other things I noticed, but probably unrelated.

M201 X400.00 Y400.00 Z100.00 E10000.00 ; set accelerations (mm/s^2) The E accel of 10000 is maybe a bit extreme. Try reducing that to 3000.

@p8blr said in Z motor stalled on "long" retracts:

; Miscellaneous M575 P1 S1 B57600 ; enable support for PanelDue

If you move that to the start of config.g the paneldue will be enabled sooner in the startup process.

@p8blr said in Z motor stalled on "long" retracts:

; Mesh Leveling G29 S1 ;load mesh leveling and activate compensation

Best not to load the mesh in config.g. It's better to either put it in the slicer start gcode after the axis have been homed.

And finally, it looks like you've got simplify3d set to use absolute extrusion. I would suggest you switch to relative extrusion.

@phaedrux

Thank you for the suggestions. I have made the necessary changes to Simplify3D and config.g

New config.g:

No, unfortunately not.

If that still causes the problem on your machine, then we can try removing lines.

p8blr

@dc42 I tried your code and it is still stalling the Z motor.

I tried commenting things out one at a time and discovered getting rid of two of the G92s stops the Z motor from stalling.

But it's so weird because the G92s can be in there if the retraction amount is just right.
(from earlier post)
.97mm and up works
.96mm to .72mm stalls
.71mm and below works

By the way, in relative mode (M83) are G92 E0 ever necessary?

@p8blr please can you try the firmware build at https://www.dropbox.com/sh/cq7q3g8coymo9s3/AABtPYEzV1_unETpKEMPInSia?dl=0. Use it with caution because it has had limited testing.

You seem to be missing some files. Please upload this zip file as is to the system tab in DWC.

That should get you everything you need to then update to the beta build.

This beta firmware resolved the issue! I will continue using the beta firmware, and keep my eye on the printer. Thanks!
