I’ve gone through several routes. I’ve been using the XY plotter with pens successfully for over a year, but the laser doesn’t seem to be working. I’m not sure which arduino board I have, but here is an image:
Please help 
Can't turn on laser; mac os x 10.10; XY plotter v2.0

Maybe I should give more detail:
- I have been using the plotter in the following way: I generated an app using Processing called GRemote. I generate .cnc files via the julia language, and make images using mathematics. See below for a couple of images of things I’ve drawn (all at the maximum size)
- I’ve tried flashing xybot.ino onto the board in the picture in the initial post. (Is it a MeBaseboard, or Orion?) I was unsuccessful. The program would not compile in the ArduinoIDE.
