So I dropped by the local woodworker's shop. He does a lot of work making little boxes, trophies, and signs, among other things. I knew that he had a small CNC router and was hoping he could cut some plates for an OX build I have on the go. He couldn't because his router was not in working order. So I looked it over and realized that a retrofit would be fairly straight-forward. So I wrote up what he would need and figured out what his out-of-pocket expense would be, at most $500. His eyes lit up at that since he had been quoted many thousands of dollars from a fellow that services this make of router and the manufacturer won't touch it. The router is a circa 2001 Camtech RM25. Leadscrews and built a lot stronger than an OX. It has a 3HP spindle on it. I've been learning a lot by looking it over. One lesson has been that having controls very near the router is necessary. This fellow's shop is set up so that his computers are in a room with filtered air, keeping the dust out. In the past, he did all his drafting work in that room, then sent the job to the router, walked to the router, did any necessary set up, zeroed it, and started the job. The router has a control pad right on the gantry. Can't say I'd put them on the gantry, but the point is that having controls on the router is very nice, almost a necessity. So this got me thinking about my OX build. The router will be in a room in our basement. I had been thinking of using Chilipeppr (and Raspberry Pi) to run it, so I could set up jobs and monitor them from upstairs. I could probably even start jobs from upstairs using a webcam to get everything in order, but that's a little dicey. In my case, I could just bring my notebook computer down to the shop with me, get the job set up and started, then monitor it from upstairs. Even so, I think controls on the router are very nearly a necessity. Has anyone given any thought to this problem? Anyone seen a solution? The 3D printer world has moved towards on-printer controls and having owned one for a couple of years, I see the value, even with my printer on my desktop right next to my computer, having dedicated controls would be nice.
