Other than dust issues is there a good reason to use magnetic vs optical? What is the production cost of the magnetic strips?

The printer we brought in is great and the board-making process works. I had to put a scaling factor in Eagle, so the prints come out the size they should. Always make measurements to ensure your print is the correct size. Grab me and I'll walk you through the photoresist process. And I'd be happy to take any boards you want to donate to my students for solder practice. NYC Resistor is now a place where you can do this prototyping.

Closed loop is great - I've been running your rotary encoders since day 2 - day 1 I tried to run my lumpy DC extruder open loop, with predictably bad results. The magnetic encoder should be fairly immune to the PLA dust that slowly builds up on my machine too, unlike an optical solution. Neat!
