before you go Arduino route check out upcoming USB-BOBDeckelHead wrote: ↑Thu Apr 04, 2024 5:03 pm Thank you, Keith, for the offer. I may take you up on that in a few months. In the meantime, I've got to work on the retrofit and such. I was just trying to jump the gun a bit and to give my brother something so that he feels engaged in the project. In the end, I am either a sucker or a very nice sibling... I found the machine, bought the machine, have collected all the parts, will perform the retrofit, and then I'll deliver the machine to him. I think sucker is probably a more accurate descriptor.
The task is moving along pretty well right now. Most of the parts have been purchased, but I opted to use new closed loop stepper over what was there (this is an old Denford, by the way), which means new mounts have to be fabricated. I'm currently in the middle of developing a schematic. Once done, I will be able to layout the electrical and decide on the appropriate enclosure. I think that is the last more significant purchase. I also will be working on some Arduino projects for the mill in the future. One will be for the ATC once I figure out the I/F in the Acorn for the ATC. For the most part, all of the logic there will be handled by the Arduino (simple 3 position ATC that is almost not worth doing except for the fact that it is all there). The other will be a modification to a typical Chinese pendant. I can't really justify the Centroid pendant, and he won't need a display. So, the Arduino will function as a keyboard mapper. That will all be pretty basic programming. The only real reason for the Arduino is really to function as a keyboard controller so that we can have a USB interface. Oh, and the Arduino will map the MPG accordingly too.
Anyhow, I digress.... I/we may be contacting you in the future regarding your off (which I appreciate), but it will be several months out.
