@MaxGyver can you also, just for completeness, provide the M122 output from your connected toolboard etc?

MaxGyver

I just upgraded the printer to a RPI5 with a clean install...still the same error

@jay_s_uk said in [3.6.0-rc.2] Code 3 move error:

@MaxGyver can you also, just for completeness, provide the M122 output from your connected toolboard etc?

Sure, here are the diagnostics of all boards including the mainboard:

@MaxGyver said in [3.6.0-rc.2] Code 3 move error:

Unfortunately not. I had the same error again while printing the firts layer.

Do you mean the same Code 3 error?

MaxGyver

@dc42

Yes, I had the same Code 3 move error. I did not copy the error code tough.

MaxGyver

The issue is also present in 3.6.0-rc.1

Error: Code 3 move error: new: start=651528999 overlap=5623 time now=651492690, existing: s=651491803 t=42819 d=20.46 u=8.0975e-4 a=-1.5504e-8 f=18

@MaxGyver please provide the GCode file that provokes these errors.

MaxGyver

@dc42

Here you go:
LARGE SOFIA LAMPSHADE.gcode

@MaxGyver thanks, I'll try to reproduce it. We haven't had any other reports of Code 3 errors since we released RC4.

dc42

@MaxGyver not related to the Code 3 errors, but I noticed this in your config.g file:

M205 X8 Y8 Z2 E10                                 ; M205 X5 Y5 Z2 E3 P0                              ; set jerk;M566 X125 Y125 Z60 P0 ;set jerk

M205 and M566 no longer do the same thing with different units in 3.6. M566 sets the machine limits (in mm/min) while M205 sets the limits for the current print, if they are lower than the M566 limits when converted to the same units. See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-RC#upgrade-notes-from-354.

@MaxGyver I believe I have identified the cause of these errors. If I am right, they only occur when the input shaping frequency is below about 12Hz, which would explain why nobody else has reported Code 3 errors since we released beta4.

Please try the new 3.6.0-rc.2+2 main board firmware binary from https://www.dropbox.com/scl/fo/nlkfneaas1osgtdw37s17/AIS_H0KSAKCmfYSjSRTSOAE?rlkey=ad4omnq36zkdz3wl8i7kthqqt&dl=0. You may keep your expansion board binaries at 3.6.0-rc.2 or upgrade them to rc.2+1 from https://www.dropbox.com/scl/fo/kj7gwwzxg5lhe26twph5z/AAdwkPCTYi6bcogLmIIIup4?rlkey=8oo6z5il7wzk2u5b7qpykf3qv&dl=0.

@dc42

I finally had a chance to test the latest 3.6.0-rc.3. When the input shaping frequency is set below 12Hz I still have a code 3 movement error always at the same code line early in the first layer. When the IS frequency is >12Hz it is working. I have attached the test pot.gcode file that is causing the error.

Error: Code 3 move error: new: start=335135293 overlap=3753 time now=335099122, existing: s=335096227 t=42819 d=20.49 u=8.1090e-4 a=-1.5526e-8 f=18

@MaxGyver thanks for your report. When that error was reported, did you still have input shaping set to 8.7Hz EI3 in config.g?

MaxGyver

@dc42 Yes, Input shaping was Set to 8.7Hz EI3.

dc42

@MaxGyver thanks.

I found a bug in the previous fix. Please try the 6HC build from https://www.dropbox.com/scl/fo/dumsdufoej44q97ek9joo/AIBRnU-wtKfMrbWPzZwH_XY?rlkey=idmyinvvcuiwmycbb1l2obz38&dl=0.
