Prusa MK3.5S Motherboard defect after mistake ?
Hello,
My Setup :
- Prusa Bear MK3.5S, Hotend Revo Six
Here's my problem: I dismantled part of the electronics to assemble the Prusa enclosure and do some cable management on my Prusa MK3.5S, and when I removed the cables, the Power Panic connector came unsoldered. 🙁
I reassembled everything without the Power Panic cable, started the printer, tested the axis movement (OK), and when preheating the hotend, I got error 28202. Since I made a mistake and the Power Panic connector came unsoldered, do you think this has rendered the motherboard unusable ?

I checked that all the hotend cables are properly connected and the motherboard fuses are intact.
