THC (Torch height control) feedback

Having enabled THC on my droid recently I got to experimenting with it. Initially I was getting mixed results. some cuts were great others the THC didn’t perform as I expected, even glitching the machine to needing a reset.

After a while of trying new things I was convinced EMI noise was causing some issues so I did a few experiments and found that a simple ferrite core on my combined THC and Trigger cable fixed every issue instantly - now having just spent an afternoon cutting with THC enabled, I have not had a single glitch.

Could I have found the answer to my problems? Hard to know for sure but thought I would share my experience incase others have the same issues.

A simple snap on ferrite core 3" from the end of my 4 wire cable at the droid end seems to have had a positive effect. (2 trigger and 2 THC divided voltage <5vdc)

@Matt_UK I know this is an old post but, did the ferrite cores cure your problems?
Did you install inline or looped?
I am trying the THC on my droid also and am getting mixed results.
Any help will be appreciated!

Hi - It is hard to say 100% BUT I have not had a single failed cut or random behaviour our of the Droid since I installed the ferrite core, so if that’s any kind of conclusion so beit.

I just snapped an inline core 3 or 4 inches from the AD end.

Thanks

So you did not loop the wire through the ferrite core.
I have heard of both types of installations but don’t know the reasoning behind each one.
I am not that knowledgeable about electronics.
Just trying to get over this next hurdle.
I am using a Iyeah CUT80CNC plasma cutter with CNC connections built in, with one of Amp mechanics voltage dividers.
I have tried adjusting every setting combination and am still getting mixed results. When I get it to work going up hill, it won’t compensate going down hill, and the same results going in the other direction.
Then sometimes it won’t work at all. This makes me think I have some kind of interference.
