My TS-30 CNC milling, drilling and engraving machine is currently up for sale. This short video demonstrates engraving single sided cooper clad FR-4 PCB. 0.3mm DOC, 15mm/s feed rate. The ample sized bed is suitable for milling PCBs and I have also found it very useful for milling PVC and ABS panels. It is accurate and highly repeatable. The machine is capable of very light engraving of soft non-ferrous metals but is not suitable for milling or engraving steel.
