Nicely done, Seb!

The HAL code that glues it all together is here, look at control-panel.hal: http://git.highlab.com/?p=emc2-config-bp-r2e3.git;a=tree I made a small pyVCP to debug all the hardware connections, it's also in the git repo above. The panel is made from some scrap 0.040 thick steel shelving i dumpstered. The labels are engraved just deep enough to take off the black paint and expose the shiny metal underneath. All the wiring terminates in a connector in the control box on the front of the machine, so i can remove the panel pretty easily to work on it, without removing all the knobs and stuff. It's got a couple of bugs... Some of the labels are obscured by the buttons knobs they're supposed to describe. Some of the mounting holes are in the wrong place, hence the C-clamp helping hold it to the face of the machine... This was a fun project because it was a bunch of firsts for me: first time engraving text (yay ttt!), using multiple coordinate systems, using polar coordinates, and first time with pyVCP. And it makes the machine so much more convenient to use! And there's room for a touchy touch panel next to it... :-) -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.

I notice that you are using the jog knob from the old Bridgeport E control panel. Are you also using the old panel mount encoder? The one that looks like a 1/2 Watt chassis mount pot? If so, have you found any data on that encoder? I have a couple, but I've never figured them out or been able to find their manufacturer. Encoding minds want know!

Hi Matt, I wired that up for Seb one evening at his place while he was playing with some very short humans who seemed to require a lot of attention. I don't really understand what was going on there, so I worked on the mill. The encoder is just unpowered mechanical switches giving quadrature. I had to add pull-up resistors (well I think I pulled up - I know I added resistors) to get it to work. If I remember right, the encoder gives 50 cycles per rev instead of the more usual 100. It is not the greatest jog wheel ever. I don't recall which of the three pins is the common... I bet one could wire it correctly in three or fewer tries though.
