[3.3 RC3] All tools heaters appears to be overpowered

[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.

@psychotik2k3 thanks. Please post the result of M122 for the main board after you have that "Bad command" message.
