@percar nevermind, i tried exactly the same thing, did not changed anything, and it's printing...
I just don't know why but it is working (not bad when its this way) .
But thanks a lot, next I will try printing with the palette.
Oh by the way what slicer are you using for multicolor prints ?

I know there are several topics covering this subject but nothing seems to work for me.

I have a duet 2 wifi which works perfectly, and I'm trying to use octoprint on a Pi 4b to run a palette 2 (really annoying to not being able to use dwc).

Basically I home and heat up the printer then connect octoprint (like mentioned here : https://forum.duet3d.com/topic/21022/duet-rrf-mosaic-palette-and-octoprint/6?_=1612197410142) but wen connecting octoprint I get various errors...

Does someone have an idea, I'm loosing faith in the palette, the concept is great but using it is such a pain.

thanks

@phaedrux I found a fuse online, it's i the mail , I'll double check my wiring and install it. So I believe there is finally no more problem .Thanks a lot for the help !!

@phaedrux
Red and black wire is a 12V small blower fan used for layer cooling
White and yellow is a 12V 40mm fan used to cool the hotend

But the problems comes very probably from the black fuse I found on documentation that it's used for Vin fans, and it's blown up...
So I probably messed up something... I'm not really sure maybe reversed polarity with dupont wires...
how can I get a replacement fuse ?

@Phaedrux The M106 doesn't works and now my always on fan works only when jumper is on 5V, mosfets don't seems damaged, and checked with a multimeter no voltage when jumper is on 12v

@phaedrux ok now it work thanks !!! Before I tried using the PanelDueFirmware-v3-7.0.zip, why isn't it correct ? G code also runs at normal speed !
I'm also using a cr10s stock layer fan but it isn't turning on, the hotend fan is working great but not this one even on the same output. Layer fan works on the psu output, could this be something pwm related ?

@phaedrux the firmware version displayed on the panel due is 3.2.11 which is the version I flashed, my panel has a ATSAM4S4B so hardware version 3 I believe.

also my start g code:

Here's the screen right now it's connected with the 4 pin but the SD one gives similar results

Sorry I didn't meant firmware I meant config, I changed the config with the online tool so I have a M552 S1.

@Phaedrux flashed the firmware screen is inverted horizontally and vertically , also weirdly yellow... The wifi problem is gone, flashed another firmware this one probably included M552 S1. I'm printing a benchy right now but it is really slow, peak speed is about 12mm/s where it should be like 40-50 trusting G-code analyser, any setting that could be involved ?

@dc42 I'm gonna bother you again I've uploaded my configs files but at startup the board wifi is off and I need to send a M552 S1 command, even after setting the network to enabled ? Oh and also I connected the paneldue it's just white, I've tried with the 4pin and the sd card cables. It's also enabled in the config tool.
