[Fixed] Error #032 - Troubleshooting [Fixed]

#1

I am actually troubleshooting a M300 that show at the start the error #032. As written on the support page, I check the connection between the motherboard and the extruder PCB and between the PCB and the motor itself.

But when I check the back side of the PCB I find some pads of the “microcontroller” seems like solder together (photo linked). Is it fine ?

As I continue to disassemble the printer I will post some photo of strange things I found.

PS : If it’s not the appropriate place to post it, if a moderator can move on the ideal place, it will be appreciate.

That was the only starnge thing for me. The problem was fixe by applying some contact spray (bombe de contacte in french).
