I've been umming and arring over the control panel for a while, and having finally finished all the major cabinet wiring and programming last week, it has reached the top of my roundtuit list.

While contemplating button/dial placement, I happened to notice the box which was about the size I had in my head. So after rounding up all the bits, I got the scissors out tonight. I was going to put the axis/step size select switches above the MPG, but having tested the layout, I felt the MPG would be too easy to knock while working the switches, which is why all that seems a bit bunched up.
I'm going to put a handle along below the buttons, so I can rest my hand on it while working the MPG.

Next step is modelling it in Fusion.
