Extra parts needed:
1a. Dual 36V/24V DC power supply
4a. Two (2x) 3MD560 3phase motor drivers
4b. Three (3x) 25mm Si reflection mirrors, one(1x) 20mm high quality ZnSe focus lens. You decide what focal point needed. Popular is 50.8mm
50.8mm OK to handle 4mm cutting or thinner object (less slope obviously) and good engraving. To do cutting on thicker object , you may consider 63.5mm or 68.5mm. But, longer focus lens take more power so you may end up running slower speed to offset the power dropping.
5a. Water tubing and air tubing
6a. Air pump
7a. Signal wires, 2-wire,3-wires,4-wires


Optional:
8a. SSR (solid state relay) and heat sink for main power control?
9a. Emergency switch?
10a. EMI filter
11a. Beam combiner (red dot targeting)
