Valid Arc Lost 2

Yes and Yes.

Thank you Phil.

So would look something like this?

Yep that looks OK.

Looks perfect. I visited Chris, one of my advisory panel on the way home just for you. This would be a good test. The 1k resistor only puts 24 mA through the relay so its still under the minimum current specification. This must have been enough to get it working in the beginning but its failed again as more oxide built up.

So be a good Sparky and duck into Jaycar in the morning and grab 3 x 270 Ohm 5W ceramic resistors. Replace the 1k resistor with these wired in parallel and that nasty oxide won't know what hit it when 267 mA goes through the relay. Hopefully after a few cycles, it will have burnt through the oxide and be working reliably again!

Thanks Rod !

I was actually in Jaycar to buy a single resistor just before! feels weird tapping a card to buy something for 70 cents.

So just and update.

I wired in that circuit and its sort of a success.

PREVIOUSLY:
- to do a straight test cut in the run tab, the Arc OK light would not light up in the bottom left and the torch would fire for 1 second, stop, give a valid arc error, retract to the max Z height, and pierce again. It would repeat this process until i stopped it.

NOW:
- I fire a test cut and the arc ok signal comes on momentarily, but then the torch turns off, retracts to Z max and stops there, (and I think it automatically triggered the E-stop). It would not keep peircing like previous.

Unsure if this points to a software issue? Perhaps any lowpass filter or debounce settings in the ini or hal files (i have never set anything for these).

I will go to Jaycar tomorrow and buy some resistors and see if this helps.

Would you mind posting your config here? If you are on v.171, you can click "backup" in the config page which will dump a compressed file into your home folder, and you can post the file here.

Otherwise your <machine_name>.ini, <machine_name>.hal, and <machine_name>_connections.hal files would work. You may have to toss ".txt" at the end, I cant remember which file types the forum accepts and which it does not.
