Been working on my CNC all day.... *almost* to the point where I can cut circuit boards.
Here's the second one I've tried to cut (first one, well.... it just looked painful).
Looks like I still have some shim work to do, and need to do a bit more math on the configuration.
But, is good enough I'm stoked... should be able to get there from here soon enough.
Posted a video of the machine using its steppers to play music. Had to switch it to half-stepping rather than the 1/8th steps I'm using for the PCBs to get it loud enough ;) Used a script from here to build the G-Code vectors.
