Hi. Great work!

Do you have a connection diagram? And did you remove the mill mcu to get it to work?

I guess it depends on what version heater you are connecting to. I connected to my Gen2, after desoldering the HF_LPT120A i connected the Wemos D1 according to the labeling on the Mill PCB. 3.3V <-> 3.3V GND <-> GND RX <-> RX TX <-> TX
