A little off topic but it related in that I hope to machine parts for a RepStrap…
I have a 12 year old Sherline CNC Mill and Lathe that use a (now defunct) AhHa controller that put out pulses to the stepper motor controllers for the Mill and Lathe. Have not touched either in a decade; I’m just getting into this by way of recent interest in 3D printing. I would like to replace this controller with something more modern. I’m certainly not the first to attempt this, so I thought I would ask here. I like the idea of the Arduino controllers and the host interface of something like Repetier that we use for 3d Printing.
If anyone has a suggestion of a path to explore or a forum that I should follow, I would appreciate it. Thanks.
