M500 not saving correctly in SBC mode. 3.2.2 Duet3
-
This may or may not be an issue but I thought I'd get everyone's opinion.
Here are my steps to reproduce.
I am running G32 on my Delta printer, when finished these are my results:
Calibrated 8 factors using 10 points, (mean, deviation) before (0.001, 0.052) after (-0.000, 0.052)(I run M500 to save the results)
Ok great. I move around and run G32 again THESE are the results:
Calibrated 8 factors using 10 points, (mean, deviation) before (-0.002, 0.050) after (-0.000, 0.050)
(still decent results, I save with M500)Now I run an M999 to reset everything and run G32:
Calibrated 8 factors using 10 points, (mean, deviation) before (-0.560, 1.155) after (0.000, 0.050)So I'm close to how bad it was before I calibrated and will need to run another 2-3 times to get the calibration back to where it was. It almost acts like it's not reading the config-override.g but I can confirm the PID parameters are in fact loaded (which also exist in the override). Additionally, the M501 is present at the end of the config.g.
I've tried everything I can think of, I even started homing before G32 and probing for Z. Additionally I've gone from 6 - 8 factor on the calibration. I've also tried it with the heated bed on and off. No matter what I do, after a reset it loses or the calibration is way off. I can understand one or two microns but half a mm seems excessive.
I would think if this were a build issue, the issue would be present after moving around a bit and running and checking the calibration again.
To add icing on the cake, I also have a tilt on the bed that I can't account for, mesh leveling does not correct it and I'm guessing it's got something to do with the calibration procedure.
Any ideas?
Specs of the machine:
- Duet 3 6HC
- Optical Endstops
- 24v power supply (tests fine)
- BL-Touch
- LDO 2004MAC steppers
One side note.. I've deleted the config-override.g and recreated it with the thought that it might be corrupt or something weird.

@Th0mpy It sounds like config_override.g is not being loaded after the reset. Can you post your config.g? Do you have M501 at the end of config.g to load config_override.g? Also, what firmware version are you running? Send M115 and post response.

You could run M665 and M666 without parameters after power up and after each G32, to ses what parameters it is using.

Below is my config and override. I can confirm with M666 and M665 that at reboot it's using the config-override parameters.

Ok, closer inspection there is something weird.
A couple of the parameters for M665 don't seem to be saved properly during an M500.

In meantime may want to upload the 3.2.2 zip file just for the bug fixes

@Th0mpy thanks for your report and testing, one for @dc42 to fix!

I've just re-tested M500 and M501. They are saving and loading the M566 tilt parameters for me. I don't recall making any changes in this area for more than a year.
Did you definitely run M500?

Did you definitely run M500?Absolutely positive. I just ran a quick test where I calibrated, checked, saved, reloaded, and checked again. I also just updated to 3.2.2 just to make sure.
-
@dc42 Is there something I can to to help qualify this more?
-
If you use M666 to adjust the tilt and one of the endstop adjustments, confirm that you have made the adjustment by sending M666 without parameters, and then send M500, do the new values get saved to config-override.g?

@dc42 Ok, I tried it, it does save it but there seems to be a formatting issue on the A and B params:

Could it be a line length limit?

@phaedrux My other printer's M666 line is much longer.

Odd, I did the same and it worked correctly. Are you definitely running firmware 3.2.2 ? Send M115 to check.

@th0mpy Are you using an Single Board Computer with your Duet 3? Your M115 doesn't report this. I just tested the following, which seems to be stored and retrieved correctly:
The resultant M501 looks like this (in part):; Delta parameters M665 L161.612:161.612:161.612 R81.896 H173.484 B75.0 X-0.843 Y-0.003 Z0.000 M666 X-1.000 Y-1.000 Z-1.000 A10.00 B10.00 ; Heater model parameters M307 H1 R2.429 C140.000:140.000 D5.50 S1.00 V0.0 B0 I0Though this is on a Duet 2 Maestro running 3.3beta2 (2021-03-10).
