Hi everyone, I just was curious whether anyone had any suggestions for programming a metal 3d printer. This project is based on sls printing, and I am using a BJJCZ Model # LMCV4-FIBER controller board to operate the galvo scanner head, and I/O for the laser. However, I've seen multiple open source software that can operate these components, but I can't seem to get communication between the board and my computer. I was looking through the packets being sent to and from the board, but I can't get anywhere with the communication. If anyone has any suggestions. Thank you.
