M500 not saving correctly in SBC mode. 3.2.2 Duet3

droftarts

@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.

Th0mpy

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.

Config-override.g

; Delta parameters
M665 L291.060:291.060:291.060 R137.213 H281.548 B120.0 X-0.090 Y0.326 Z0.000
M666 X-1.052 Y-0.498 Z1.550 A-0.00 B0.01

Before reboot:

3/27/2021, 7:49:19 AM	Connection interrupted, attempting to reconnect...
DCS has been stopped
3/27/2021, 7:49:19 AM	M999

Endstop adjustments X-1.05 Y-0.50 Z1.55, tilt X-0.27% Y1.42%
3/27/2021, 7:48:53 AM	M500

After reboot:

3/27/2021, 7:49:41 AM	M666
Endstop adjustments X-1.05 Y-0.50 Z1.55, tilt X0.00% Y0.01%
3/27/2021, 7:49:22 AM	Connection established

So it seems that M501 is working, it pulls the proper tilt, but the M500 does not save the updated tilt.

I'm going to recalibrate and run M500, I'll post the config-override.g

Th0mpy

Ok, here we are.

M666 X-1.135 Y-0.455 Z1.590 A-0.00 B0.01

The config-override.g isn't being updated with the tilt on an M500. I can confirm that manually editing the value does work.

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?

Th0mpy

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.

Th0mpy

@dc42 Is there something I can to to help qualify this more?

dc42

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?

Th0mpy

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

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

droftarts

@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):

Phaedrux

It would appear that DSF in SBC mode isn't saving the config-override.g correctly. One for @chrishamm ?

chrishamm

@phaedrux Yes, that's right, the tilt factors must be multiplied by 100 before they're written to config-override.g. I'll fix that in the next version.

Th0mpy

@chrishamm Will that fix it from not saving at all with M500 after calibration?
