I've got a FLSUN Kossel Delta with a MKS Gen L 1.0 board running Marlin 1.1.4. When it's connected to my computer via USB/Repetier, everything works fine, e.g., I can change temperatures from my computer or through the lcd controls. But if it's unplugged from the computer, and I try to change extruder temp or bed temp, the heater turns on for maybe a second before the board automatically resets. The same happened when I tried to print via sd card. I chose the file, it started heating for a second, then reset. This sounds like some kind of fuse issue, like it's drawing too much current, but I can turn on the heaters when it's plugged into the computer without any resets. Any ideas what's going on?
Thanks,
Alex
