Howdy every one,
I upgrade the UM2 firmware to Marlin 1.1.x version, so I could have access to BLtouch and some other extra features. The printer is working fine except for two things:
The Hotend auto fan will not work, no matter what I do. (same issue as here : )
The controller leds behind the nob will not turn on.
Is there anyone who have a fully working UM2 with BLtouch able to share the firmware files or help?
Thank you in advance,
