Unsolved [3.3 RC3] All tools heaters appears to be overpowered

[psychotik2k3]

edit: i say error because the printer stopped my tool change in the middle of the Tpost1.g file where it undock the tool 1)

just upgraded from 3.3 rc2 to 3.3 rc3 to check if the bad command bug was fixed (short answer is no) and during a tool change i suddenly got this error on ALL 3 heaters (got 3 tools)
"Warning: Heater 1 appears to be over-powered. If left on at full power, its temperatur is predicted to reach 446C"

and the same message for heater 2 with 646C and heater 3 with 723C.
all 3 heaters where configured with an active and stand by temperatures of 0C as i was just testing docking and undocking and if cables holders where messing with other tools.

here are my M122 of both cards:

[Alex.cr]

@psychotik2k3
This is just a warning. It’s not an error, it doesn’t stop you from doing anything. That is weird that you have not seen it prior to RC3.

Out of curiosity, are all three of your tools the same physical setup?

[psychotik2k3]

@alex-cr no they are all different, a bmg clone with nf crazy plus (mosquito clone)
a biqu H2 and a bondtech LGX FF
i got 2 types of thermistor and 3 different configurations for that.
and it's not only a warning as it stopped my tool change in the middle with the code of tpost1.g not finished.

[gloomyandy]

@psychotik2k3 said in [3.3 RC3] All tools heaters appears to be overpowered:
That looks like your board may have reset (so the messages will have been generated when re-reading your config.g file). The M122 is reporting a reset due to an AssertionFailed which I suspect @dc42 may want to take a look at. It may help for you to post your tool change macros.

[psychotik2k3]

@gloomyandy of course here are my files and the complete config.
i launch the torture test macro. and it happened in the middle of the first T1

[1_1622311463966_sys.zip](Uploading 100%) [0_1622311463964_macros.zip](Uploading 100%)

[Phaedrux]

You cannot upload zip files to the forum. Can you upload the .g files directly?

[psychotik2k3]

@phaedrux oh crap... there are a lot of files....

torture_test_tool_change.g
move_square.g
config.g
homez.g homey.g homex.g homeall.g
tpre2.g tpre1.g tpre0.g
tpost2.g tpost1.g tpost0.g
tfree2.g tfree1.g tfree0.g

[psychotik2k3]

@psychotik2k3 i had to rename my macros with a .g to be able to uplaod it. so it's allright that the macro file does not match the M98 exactly

[psychotik2k3]

@dc42 any news about this bug and the bad command on the panel due ?
do you want some debug logs ?

because for now the 3.3 is unusable as i got interruption even for a simple job taht cycle through my 3 tools.

[Phaedrux]

So you're getting bad command errors on the paneldue during prints?

[psychotik2k3]

@phaedrux yes wasn't able to finish my torture_test_tool_change file
or sometimes even when just laucnhing a bed align through the button on the panel due

[Phaedrux]

This has been noted a few times in RRF3. There's something that makes it more sensitive to picking up interference as bad commands, or rather, it used to be rejected and now it's being interpreted as a bad command. In most cases improving the wiring for the Paneldue solved the problem.

Can you show us what your wiring is like for the Panel?

I've also asked DC42 to check the assertion failed error report.

[psychotik2k3]

@phaedrux i do have a cable that's near motor but as i didn't had problem with 3.2 never thought it could be that.
gonna try to rewire elsewhere and wheck if it fixes or not.
an i suppose i have to do the same thing for the can bus wire between my mainboard and my h3c ?

[Phaedrux]

Which paneldue firmware version btw?

[dc42]

@psychotik2k3 please try the new firmware .bin file at https://www.dropbox.com/sh/nmpsl9a3jfsumm5/AAA6adSjEcd1AM_j5_tVberGa?dl=0. I expect this to fix the asssertion failure.

[psychotik2k3]

@dc42 ok i will try that because i rerouted my panel due wires and canbus cable to be away from motor and motor cables and it fixed nothing.
here is the point where the panel due is the closest to a motor/wire motor:

[psychotik2k3]

@dc42 seems better but i still faced one on "home all" after a reset, and i faced a warning message "M9 command is not supported" at the end of a G32 (14:46) initiated from the bed button on the panel due.

and i just have a reset of the whole board in the middle of a movement.
so it seems a little better but still not good.

here is the debug log i have and the M122 for both cards

[dc42]

@psychotik2k3 thanks. The M122 B1 report shows that the EXP3HC reset 10 minutes before you generated the report. Was that board already running 3.3RC3 at that time?

PS - I've put new main board firmware at https://www.dropbox.com/sh/nmpsl9a3jfsumm5/AAA6adSjEcd1AM_j5_tVberGa?dl=0 to fix the cause of the main board reset.

PPS - I've also put new EXP3HC firmware at the same location, in case a fix in it is relevant to the assertion failure.

[psychotik2k3]

@dc42 thanks i gonna try that. i think the board was resetted 10 minutes ago by me on a general abort. but yes it was already in RC3.
i get back to 3.2.2 to do some tests so i go back to this new rc3+1

[psychotik2k3]

@dc42 ok just get back from 3.2.2 to your 3.3 rc3+1, updated dwc, then sdiap then mb6hc, then H3C. power off and on.
jsut after power up here are my M122 for the boards

but after that i faced a bad command just at the end of my home all once the home is finished , i was able to reproduce the bad command if i do some stuffs movement tool change etc and if i do a home all again.
here is the error and the home all gcode:

@dc42 But the good news is taht the board didn't reset itself at all, i was able to perform 4 times my torture test while i couldn't finish even one before.
So yes i validate the assertion that reset the board fix.
