Mar 12, 2013 · Jerome miles is raising funds for Jog It! Open source controller pendant for EMC2 and Mach3! on Kickstarter! Jog It! Is an open source hand held controller designed to make running a program in Linux CNC (EMC2) and MACH3 a breeze.
Galil: Galil motion control boards have been around a long time, have available Mach3 plugins, and are higher end alternatives. I’ve personally seen a Galil card work well with Mach3 to make molds for a carbon fiber project. Be sure to check Galil’s application notes to see which of their products are Mach3 compatible.
