I solved it by disconnecting the sbc and do the 3HC update in standalone mode.

Se discussion in https://forum.duet3d.com/topic/20065/new-software-bundle-3-2-beta4/12

undefined

@chrishamm Worked fine in stand alone mode

Duet EXP3HC firmware version 3.2-beta4 (2020-11-26)

So I have no excuse to by an Atmel-ICE.

@dc42 Does it make sense to test with the sbc disconnected?

undefined

@dc42 It is...
/opt/dsf/sd/sys/Duet3Firmware_EXP3HC.bin

-rwxrwxr-- 1 dsf  dsf  123K Nov 26 20:36 Duet3Firmware_EXP3HC.bin

undefined

Uploaded the new firmware to the system folder using the web ui. Now i get lots of:

Error: Firmware file Duet3Firmware_EXP3HC.bin not found

undefined

Updated using sbc without errors. But I suspect that the EXP3HC failed. Get lots of:
Error: M569: Response timeout: CAN addr 1, req type 6018, RID=1

and similar for all expansion board related commands.

undefined

Managed to reproduce the mid print halt again. This time with 3.2-beta3.2. Same behaviour ui reports 100% complete but there are lots of gcode in the buffer.

The latest beta and a replaced crimp has solved all other issues. But this remains...

The event log is empty and i didn't run with the extra monitoring on the sbc this time.

undefined

Think I found a bug/limitation in the expression code. Verified using the latest beta (3.2-beta3.2).

This expression is accepted, but doesn't update the E value:

M906 E{0.7*sqrt(2)*1400}

This one works:

M906 Z{0.7*sqrt(2)*1680}

Tested with expression for both my E with the same result.

M906 E{0.7*sqrt(2)*1400}:{0.7*sqrt(2)*1400}

Is this a known limitation?

undefined

What type of couplers to you have between the stepper and the leadscrew?

And how does it feel if you decouple the stepper and turn the leadscrew by hand?

undefined

@TypQxQ Will test that as soon as I soldered on a new switch, thanks.

undefined

Updated to 3.2-beta3+3-ch and the skipping issues are gone all works with bed mesh compensation activated.

Will run some long prints this weekend to see if i can reproduce the mid print stop with 100% complete status.

undefined

@TypQxQ Thanks, disabling the bed compensation solved my X/Y skipping issue. Strange that things got worse after the update to 32-beta3, I use the same settings and same bed mesh.

So one down, will start a long print tomorrow to see if I can reproduce the stall with the new firmware.

The version update also brought a new issue. Something has changed since 3.1 that breaks my Z-homing from time to time.

	; Home Z Axis
	M561 ; Disable any Mesh Bed Compensation
	G90 G1 X150 Y150 F10000 ; Move to the center of the bed
	M558 F500 ; Set the probing speed
	G30
	M558 F50 ; Set a slower probing speed
	G30
	G32      ; Run 3-point bed calibration defined in bed.g
	G29 S1   ; Enable Mesh Bed Compensation
	G1 Z5
	G1 X50 Y50 F10000

It is as if the center probe ends with the bed too high and drags the z limit switch against the be so i snaps. Not always but i'm on my second broken switch today after max 10 homings. Never got that behaviour in the old version. (And this is before the bed mesh is applied)

undefined

Turns out that 3.2-beta3 will make this a lot easier to track down the skipped steps that I thought i had worked around. Now I can easily get it to skip steps with just a couple of quick moves.

Same printer, same gcode and 3.1 no missed steps for 9h+. 3.2-beta3 missed steps first layer, missed step after 5 rapid moves and also manage to break the z switch after what i think are missed steps on z. The bed was skewed as if one of my 3 z motors skipped.

I will try to reproduce it on individual axis when i get time after work. Thinking rapid diagonals to test each X/Y individually and rapid z with a dial gauge near each z-motor.

undefined

Switch to 3.2-beta3 and increase event logging M929 to debug level. Will start a longer print tomorrow to see if i can reproduce the issue. Anything else I can do to get more data to help pinpoint the issue?

undefined

Yes both issues are/were consistent both with SBC and stand alone. The stall happens about once every 10-20h of printing so far but the machine is fairly new so not much data points.

I got a couple of strange stalls from different prints. The printer, a Jubilee3d, stops in the middle of the print, the ui reports "Printed wardrobeD.gcode, 100 % complete". M122 reports "File /opt/dsf/sd/gcodes/wardrobeD.gcode is selected, processing" and all heaters are turned off.

I hooked up a SBC with the hope that would solve it (and a different issue more about that later) but still run into it.

Just got the printer working and I'm new to RRF so any help on how to get more insights is more than welcome.

The other, hopefully unrelated, issue was frequent skipped steps. I managed to work around it by moving the X/Y motors to different drivers on the same card. Works fine now but would appreciate ideas on what to do if it happens again.
