M500 not saving correctly in SBC mode. 3.2.2 Duet3

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:

; Delta parameters
M665 L291.060:291.060:291.060 R137.239 H281.544 B120.0 X-0.138 Y0.266 Z0.000
M666 X-1.000 Y-1.000 Z-1.000 A0.10 B0.10
; Heater model parameters
M307 H0 R0.630 C141.300:141.300 D4.00 S0.75 V14.0 B0
M307 H1 R2.227 C104.400:104.400 D6.00 S0.75 V14.0 B0

Am I going crazy here?

Could it be a line length limit?

Th0mpy

@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 I0

Though this is on a Duet 2 Maestro running 3.3beta2 (2021-03-10).

Here's the result of M115:

FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.2.2 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2021-02-11

I am running in SBC mode.

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?

Th0mpy

@chrishamm do you know when you might have a version to test? I'd be happy to give it a whirl.

Th0mpy

@chrishamm and @dc42 Hey guys, just checking in. Did these updates make it into 3.3.0-b3? I just saw that was released but didn't see anything in the release notes. Can you let me know when I can give it a test?

chrishamm

@th0mpy Those changes are part of the 3.3-b3 pre-release. Feel free to test it again.

Th0mpy

@chrishamm @dc42 that solved it! Thanks guys!
