Extruder tuning worked fine for me too - rock solid line during first print. Bed tuning did 30 cycles, but seems to be working fine. This is a fairly low powered bed tuning to 60deg - each 5deg cycle took about 3.5min. This is with a stand alone 1.01 Duet2wifi.

What's saved in config-override.g with M500:
M307 H0 A424.4 C543.6 D5.5 S1.0 V24.1 B0

What the M303 H0 S90 came up with:
M307 H0 R0.781 C543.6 D5.54 S1.00 V24.1

Is the M500 supposed to change the M307?

Yes, M500 is supposed to rewrite config-override.g including the new model parameters. I can't see anything wrong with the code, so I will try to reproduce your observation.

@dc42, @chrishamm, after updating to the latest release i am having assertion problems again.
I publish the report. Let me know if you need more information or if I need to check

@dc42, @chrishamm, I checked, it seems that problem is due to restart of printing after a stall. For the moment I have tried increasing S value in M915 to see if it repeats again.

appjaws

@dc42 just to let you know, the new auto tune works well on my coreXYUV Duet 2 machine with RRF 3.2beta3.2
Thank you for all your hard work.

Thanks for the update. How did you have the stall detection configured when you had the problem?

Marco Bona

@dc42, the code was this:

M915 X Y T20000 S12 H128 F1 R3

In all honesty I never understood how to calibrate it correctly but with this values it gave good results.
I simply increased the S value from 12 to 15. I can't tell you if the same assertion problem also occurs after resuming a print from a pause.
If you need feedback I can give it a try.

Especially the bed took quite a while, but that's a lot of thermal mass.

I am not noticing much better PID behaviour when the print cooling fan is suddenly turned on from 0% to 100%; without silicone sock the hotend temperature drops ~6 degrees C and recovers fairly slowly. 100%->0% gives a 5-6 degree C overshoot. RRF3.1.2 behaves about the same under that condition.

gloomyandy

@DaBit Try using the tool number rather than the heater number so:
M303 T0 S250
assuming H1 is the heater for T0. If you do this then the tuning will run an extra cycle with the cooling fan for tool 0 active and you will get some extra params which may help with your temperature drop.

DaBit

Thanks for the hint, 'old' habits I guess..

Makes not much difference though. Recovery from fan torturing is slightly faster, temperature deviation stays approximately the same with -6.5C /+5C.

Cooling fan turn-on / turn-off event, no silicone sock:

Of course, I could improve a lot on this by making fan airflow more directional towards the print, but there is no print-quality reason to do so. Better save those lessons learned and time to resolve them for printer #2. There are more things that did not work out as expected and need improvement, such as the E3D Chimera.

I normally use silicone socks around the heater block, especially when printing small items, although at 250-270C hotend their lifespan is a bit limited.

Is there a reason why we don't have a derivative term in the controller? Or is that derived internally from the R/A, C and D parameters? The D usually works fine dampening an otherwise too agressive P and reacting to fast environmental changes.

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

That's because you didn't use a T parameter in the M303 command to tune heater 1, so it didn't run tuning with the fan off and then on.

It did. I used M303 T0 S250 to start the tuning.
At 20:19 it started phase 3 with fan off, at 20:22 with fan on. DWC also confirmed the fan being on at 100% (I admit: I was not physically next to the printer, so I did not verify if the fan was actually blowing air, but I thrust the software enough for that), the tuning ran for 10 cycles instead of 5, and the C values for fan on/off in the resulting M307 are quite different.

@dc42 suffice to say I have a prerelease 1LC board (with updated bootloader) and a Duet3 rev0.6 board.

I still get the odd report that transfer data pin not ready. SBC has own 6amp PSU and connected via genuine ribbon cable.

Also, where have my plugins gone?
