Hello good friends!
I'm writing this lines only to announce a really stupid mistake I've done!
WITHOUT reading end documenting like I usually do in such circumstance, yesterday I've introduced in my fresh, new build Voron printer, this little module: https://biqu.equipment/products/btt-ups-24v-v1-0-resume-printing-while-power-off-module?_pos=1&_sid=656c815f9&_ss=r
BTW I'm using Klipper and this function of resume printing on power loss (as I read it afterwards) is not yet implemented! But I didn't know at that time... Maybe, it wouldn't destroyed my MCU if I'd use the same connector as for the normal 24V BUT as you know there are 2 possibilities to power this module and also because of the limited space available, I put this UPS on the other port... Connected correctly (+) and (-)...
No smoke, no nothing, the Mainsail has started as usual but Klipper after a while gave this "unable to connect to MCU" error ... so basically that's all... SKR is useless now. Desperately, I've tried to re-flash the firmware but it was pointless...
I'm still amazed of the "wonderful" work I've done!
