@Fishing_phil Hello; I am new on 3d printing. I have recently bought cp-01. I have tried 3d printing and results are good. But I need to make my own PCB's and this was why I have bought cp-01. In recent days I am trying to use FlatCAM to engrave my pcb's with CNC. I export gerber files from proteus. Doing settings on flatCam. But I could not change cutting speed anyway. I have tried many values for feed rate option but nothing changed. I need your help for firstly this PCB issue. And another question: Can we use laser engraving for PCB producting? Thank you so much.
