Workflow for PCB making:

Paint board with flat black acrylic paint.

Design board in CiDess, no borders. Create GIF PCB, x10, mirror, normal. Lands in CiDess directory.

Convert to Gcode with RasG. Lands in pdat/TwoTrees.

Start laser in lower left corner. Use web browser or phone app. Grid starts at 1x1 mm. Place board on grid. Move to lower left of overscan area, reset home ("Position XY" in browser, droplet in app). Check proper start position.

Engrave. 

Clean (alcohol, paper tissue, toothbrush).

Etch.


6000 mm/min, 75%, as starting settings. PWM frequency set to 10kHz. Default accel.
