Is it normal that while the printer is idle the toolboard reports about 10 lost messages per second?

Duet 3 in SBC mode running 3.2beta3.2 as the host system. The LEDs blink in sync (and obviously CAN transfers do work).

I see the same thing. Added to my list for investigation.

Are you definitely using the M307 parameters that were reported by auto tuning, and not overriding them with M301?

18-11-2020 20:31:33	M307 H1
Heater 1 model: heating rate 1.941, cooling time constant 335.4/173.7, dead time 6.34, max PWM 1.00, calibration voltage 23.8, mode PID
Computed PID parameters: setpoint change: P14.5, I0.315, D64.4, load change: P14.5, I0.819, D64.4

This is after a restart of the board. Looks like the tuning parameters are set correctly.

Your tuning results show a bog difference with the fan on, so I would expect the feedforward to make a difference.

No silicone sock and a sudden tornado is quite worst case. That tornado also helps tremendously to speed up the toolchange with the Chimera so I am happy with it; I cool down and wipe the inactive nozzle until the plastic has frozen, otherwise getting anything close to acceptable results using a Chimera is close to impossible.

Under those circumstances I don't think the -6C drop is a bad result at all. There is lag between heater and sensor, and there is only so much a 50W cartridge can do. Compared to RRF3.1 the new feedforward does not help, but it seems not to hurt either.

I assume 'feedforward' is setpoint feedforward? Do you use a curve to adjust for ambient-hotend temperature differential and/or scale the feedforward with fan percentage? Maybe feed a portion of the fan percentage into the D term of the PID to provide a temporary boost/drop in heater power?

DaBit

Not sure where to post it, but I have a file that won't print and I haven't seen the behaviour before 3.2beta3.2 so it might be beta-related.

Printer stalls early in the print (as in: no movement at all), and stays there indefinitely until the board is reset (cancel print does not work, emergency stop does).
When the board is reset and the print restarted, the same happens again but in a slightly different location.

Looking at the code it is not quite what I expected (absolute E-coordinates, and many very small moves). Those are user error and easily fixed, but the Duet should not hang on it either?

I am not very concerned, other prints run fine so it is probably a matter of re-slicing with correct settings, but I thought it might be useful to someone.

dc42

Please test that file again with beta 4 when it comes out (probably tomorrow). If the problem persists, post the file where I can retrieve it.

DaBit

OK, will do.

This morning I did reslice with my usual settings (relative extrusions, usage of G10, cap on resolution), print is currently at 12.5% and progressing fine, hiccups counter stays at 0.
My gut feeling says that the huge amount of short segments in the original code is what causes the issues.

In advance; the G-code file can be found here: https://www.icecoldcomputing.com/directlink/stackable_OD5.5_ID3.2_H3_bush.zip

@DaBit, 3.2beta4 for Duet WiFi is released now.

Veti

@dc42

from the changelog.

Efficiency improvements to TMC2208/2209 drivers for both main and tool boards

Which board uses the TMC2208? did you mean TMC2224?

Yes, I did. I think of the TMC2224 as a 2208 (it's the same with a different pinout).

Makes no difference. Skirt goes well, once the printing of the circles starts the Duet hangs (cancel print does not work, emergency stop does, changing temperatures in DWC does too)

You've posted the print file, but I need your config.g file too.

DaBit

@dc42 : Here is the entire bundle, directly downloaded from the printer:

dc42

Thanks, that's on my list to look into.

DaBit

It is not an issue for me. I suspect the large amount of short segments simply choking the Duet. When using gcode with sane segment length the Duet hums along fine.
But still, it should slow down to a crawl, but not hang.

dc42

Absolutely right, it should not hang.

dc42

I believe this is now fixed in the new RRF 3.2bete4+3 binaries at https://www.dropbox.com/sh/tehhdvunh0pgr7q/AADgJ4Qj7W18MYaRRNNDdhpwa?dl=0.

DaBit

not fixed or 'now fixed'?

I will give it a try, will report back...

DaBit

The issue seems resolved.

I did not let the print finish since that's only a waste of plastic and I don't think it proves anything, but after 63000 moves it was still printing fine.

dc42

Thanks for confirming.
