While I see that I need to get better at asking questions because I didn’t quite get an answer to what I was really asking, I do appreciate your insight into “Star grounding.” I have made a mental note of it and actually, all of my components installed thus far are grounded at a single point. Th

Greetings Peter; Because I've too many microfarads in the spindle motors analog supply, I have a charge pump running into a pair of nand gates, with the other inputs controlled the the machine enable, signal with a 3 second time delay between enabling the supply thru a 50 orm 200 watt resistor

I remember those. But the guy on the Youtube video had access to free IR receivers from a salvaged scanner and these where spaced 1,200 sensors per inch. Also and I think this was a very good idea that HP did not think of, THis new machine does an NxM search at every frame so there are NxM poss

HP made a CRT monitor that had IR emitters and sensors aimed vertically and horizontally. They had to be mounted pretty far forward to clear the curve of the tube and resolution was very low. Software using it was limited to having its active spots at the intersections of the emitter and sensor

I do have plenty of isolated inputs and outputs for that and my plan was to use those. But as I got to wiring it up, I thought it would be really neat to hook up all wires from each motor cable to their respective stepgen headers. This isn’t possible, I see… so back to the initial plan. As a re

A cheaper way to sense position is the scanners used in store checkout systems. There is an octagon shape mirror that spins and a laster is aimed at the mirror. Then you need an IR photodiode. It's cheaper because you can use a one-pixel sensor. On Sat, Dec 1, 2018 at 9:44 AM Gene Heskett wr
