Machine: K40. Can’t remember which board it was, think it was a nano. Has the three white wires on it which you use the middle for the power control?
Board: Cohesion3D mini (from about 2+ years ago)
Firmware: “I have a new board and I’m using whatever it came with”
Problem/ Question: got an issue with the LCD showing just weird QR code like characters. Just swapped out the power supply from stock to HY-T50 and added a dedicated 24v supply for the board. I’m assuming this is grounding or over voltage issues. Have I done anything wrong?
