Firstly, I have to confess I’m nothing whatsoever to do with the wood carving community, although looking at your work I wish I was ! I’m a retired teacher from Birmingham,UK and I’ve taken to electronics to keep me out trouble with the Senior Manager I married.
I have a small milling machine, linked to Mach3 which I use to make PCB’s and I’ve been trying for the past couple of months to make a Jog Control for it without much success.
I was impressed to see that you have done this in a number of guises, and even more impressed that at one point you threatened to post your Arduino Code.
Is there any chance of a copy of that code so that I can see where I’m going wrong please … ??
