Urgent issue #31

Open JamesD3d opened 3 years ago

JamesD3d commented 3 years ago

Upon loading the new bootloader, USB Counication will not establish, New firmware.bin files will not flash. The board constantly reboots and the MCU is extreamly hot.

More importantly. A major issue with thermal runaway. All heaters on the board when recieving power for the main begin to heat uncontrollably. this occurs with the Bed, Heater 0 and 1 (I note that all the indicator lights for the heaters are on.

This could have lead to a fire or metdown. I've seen several other posets in varrious forums to this effect.

@DJames2682 I know that this is not a forum but... If you are no more able to flash the MCU through DFU or SD card, you can try to program it with the ST-Link Programmer and write the older bootloader.

It is not but I thought the situation with the thermal runaway warranted someone looking into it. The board will connect to the pc but the software will not recognize it.

As far as I understand this was because of some incorrect wiring on the probe. Is that correct?

Yep. Had the pins switches on the z endstop w/ a bltouch....not entirely sure why I caused the heater issues
