Sermoon D1 4.2.7 Board Upgrade Firmware
thingiverse
blew my 4.3.1 piece of crap board so I took it upon myself to make a upgrade path for the Sermoon D1. its too much better without the noisy drivers. the print quality goes thru the roof too with the silent steppers driving the extruder. PID Tuning on the nozzle and bed are included too. as well as thermal runway protection and arc support.
