@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.

@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.

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.

@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.

I don't think that's normal. I will see what my toolchanger reports later today.

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.

chas2706

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?

jay_s_uk

@chas2706 that's machine specific plugins. The ones you want are under the general tab

I'm sorry, I was reading your post on a smartphone and I omitted to scroll down enough.

Are you definitely using the M307 parameters that were reported by auto tuning, and not overriding them with M301? Send M307 H1 to check. Your tuning results show a big difference with the fan on, so I would expect the feedforward to make a difference.

appjaws

I have just noticed that my hotend overshoots by 10 degrees on first heating and then falls back and maintains a very stable value.
Under the old system you could adjust the A parameter to compensate.
In the M303 line I used P1.0, should I have reduced this? if so what could be a sensible value?

Using pre-release and v0.6 boards should make no difference, if they are running up to date firmware. There have been no changes to the CAN hardware between revisions.

Thanks for the info. I was wondering what the difference is.
