Hypersensing questions

Earlier in the thread, Peter did suggest we use relays to prevent electrolysis as you stated.

Yeh I think probably I told him that very early in the piece which I why I reinstated mine. I think it was Islander261 who had that advice but he did not have any first hand experience, but it makes sense now. Adding DC relays actually breaks the whole concept behind Hypersensing which was to have noting in the DC circuit. I would try to avoid it. The power supply must have some capacitors in it as it takes a long time for the LED to go off. I Actually saw the voltage count down in halshow today which was wierd. I think I had a similar lag on the first probe as the capacitors charged But plasmac recovered from the error.

I might look at motion.motion-enabled and see what it does. Otherwise, I might use motion.motion-type where it is > 0.
We just want to kill the circuit when its not running.

Anyway 8:30pm here. I will look at the component switch off but probably not until the weekend... Please keep us posted during the day shift

What would be the overall harm in having a relay on the dc side? In other words, why was this being avoided? I would think the original concept might not have accounted for the need to turn it on and off immediately?

I would honestly think the consumable would wear out before electrolysis is a problem... but maybe I’m wrong :shrugs:

Well there is 300 odd volts floating around on the DC side which says its not a good idea. I just think it should come on at the start of a job and go off at the end of it. Normally, I'd use spindle on, but I don't tink that works cos probing happens before it. I'll work it out. It was easier to just remove the relay ...

Oh yea I always forget about the pesky torch.

How would it trigger for the probe tests, etc?

I got my 22kOhm 10W resistor in (I bought a few different sizes/power ratings, decided to step it up to keep things extra cool) and wired it up.

Did a series of hole patterns without any fault and then successfully cut out some house numbers.

I saved the halscope data file only to find out that the "Open Data File" function was never completed so I can't view it. I'll take some more data next time and screenshot.

yes, you need to do screenshots. I have imported that data into a spreadsheet before though. Which Component were you using? The original? or the revised?
