I spent the afternoon learning to engrave text using Shapeoko.
- Ideal depth is around 0.01".
- GrblController doesn't appear to put the controller back into "relative position" mode at the end of the run, which can be dangerous. I should build an emergency stop so I don't have to yank the USB cable from my laptop.
- At 0.01" target depth, work area flatness becomes very important. Time to mill a flat work surface off my waste board.
- I need a bright light to tell when the bit touches material when setting up position.
- I need a font that generates a single-pass per letter, not inner and outer outlines, which greatly reduce quality of lettering.
- Plywood is a bad choice for lettering this tiny (0.2" height!). A lot of the isolated areas didn't stay once isolated.
Glad I didn't try this as a finishing step on a milled iphone dock or anything else!
- finish wasteboard clampdown paths
- mill flat wasteboard
- get bright positionable LED light
- get emergency stop button & limit switches
Update: Looks like the font you should use is the one that is initially set when you use the Hershey Text extension. It's called "Sans 1-stroke".
