Definitely doing this today.
But im looking to do mine a little different.
Ill change mine so it moves in 0.1mm increments only, with a potentiometer adjusting the feedrate.
So i can just hold the joystick down and have it constantly sending a signal every 10ms or so.
Ill adjust the time delay with the feedrate so a faster feedrate means to send the movement command faster. and a slower feedrate sends the command slower.
thanks for the starting point. Ive been hoping for something like this for a while.
