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

single phase 240 v ac that what usually residential area have.
phase to phase 240 v ac, and phase to ground 120 v ac.
it work.
i start think that if i use inverter that will take single phase 240 ac and
convert it to 3 phase may be even bett
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.

doing. If price is critical used POS terminal monitors are often available
cheaply.

I've been thinking about how to implement a touch screen of sorts on a 19"
monitor. The TFT displays are too expensive for their size.
Then I came across this;

Very interesting, and with more scanners and LED's it could be very usable!

Are you sure that the servo drive won't work off single phase? The first
stage of nearly all of them is a rectifier and smoothing caps, so single
phase works ju
