There's allot more to this than I realized and while I love to learn new things, especially PICs and all electronics I think maybe I should go with encoder/decoder chips like THESE and then do the PIC LCD from that.
What do you think about going that route ?
Range only needs to be 50 to 70 feet at most.
And it's your site I bookmarked, sorry about that, very interesting site !
Regarding your question about my CNC setup, it's mostly a hobby setup. I converted a Seig milling machine to CNC and I use Mach3 to control it. I do think there are more outputs from Mach3 I can use but buttons and sensors will suit me fine for now. I do have output functions setup with it to turn the motor and the flood coolant pump on and off per the G-code via an optically isolated relay board I made for it.
Below is a picture of a pendant I made to do the basic functions of the CNC mill so I almost never have to touch the keyboard and a picture of the drivers and power supply in a PC tower case. The perfboard seen is a 12F675 that toggles the power on off via the OEM momentary push button on the front of the case. This picture was taken before I installed the dual optoisolated relay board in the case, also added a second large fan.
Thanks for your help
