I have installed Klipper with my ender 3 v3 SE. It’s working, but after a while (about 30 to 50min), the printer stop and I have the message of mcu failed, firmware restart … The mcu temp is about 41° and the RPI 71°.
Any idea where the problem could be?
Thanks
I take it you have a device attached to the V3SE to run Klipper, which device did you add? Might give us more information to go with.
For instance just a raspberry camera, a small fan now to decreasRPI temperature and a touch screen of 5". But I have seen two warning messages telling that the RPI was undervolted and the frequency had been reduice. I am going to test a new alimentation, nevertheless it was an alimentation dedicated for RPI!!
My alimentation is 3A, I have one of 4.2A, I am going to try with it
Is the mainboard cooling fan running, it may have become detached or failed. I’d try putting the printer on spacers and running it without the base to see if you still a temperature problem.
