Not quite sure what you mean by open source.I have searched the internet to find out more information about MKS-DLC but without big success.Your github repo contains only windows driver software, hex files and some old grbl software for uploading to arduino but nothing about your MKS-DLC v2.0 boardMostly what you find are seller of some MKS variants and some conflicting pinouts for connecting to various CNC/3Dprinter hardware all in Chinese with some automatic English translations which, btw, are quite poor.Q. Schematics & software sources (that can be build without guessing)Thanks.
