Tried both with points and .3 circles (max/min holes size set to .5/.1)

SheetCAM won't produce G-code for the pierce locations, just get the tool header in the program....

Well I cut out a diff ring in 3/8" and the THC won't work. The plasma was fine and hasn't made noise since I cleaned the internal filter.

May be unrelated things going on. Still troubleshooting....

I'm still picking at this, but have an update. I'm using the supplied serial cable......there are differences in them? the dthc was working before, this isn't a new machine setup, I've been cutting...

Cut a bunch of 3/8" last night, no problems.

Still heard the little noise, but i'm beginning to suspect its a small internal air leak. I have a good supply, constant pressure, but I see the air...

I've had a couple of occurances this week of the PM45 making little internal scratchy/static...

I think i read something about using the drill cycle in sheetcam? haven't tried it myself yet.

setting the offset in Mach3 config/Zhome will not help the THC post, only manual Z homes.

you have to add "switchoffset post variable" when doing your toolpaths. its the big "V" on the side menu...

thx!

uh - I'm still getting my head around where to post for best answers, new to all these forums. I thought this was the correct place. (wrong) its labelled as "Mach Software (ArtSoft software) >...

there are no buttons on the pop-out jog menu. its blank with some led's and labels. no skin, no functions.

:confused:

pull the cover, take some pics, read the manuals over and over, and ask for confirmation where to hook stuff up once you think you know.

I'm just like you bud, never did this stuff before. ...

yep, first pic is literally the first cut. Lots to play with.

thx for the help!

yep, the continuity check from the Powermax45 ground clamp to the work clamp on the card worked perfect to confirm the polarity. thx.

The pop-out jog screen from hitting 'tab' is not functional.

the buttons don't work and there is no...

i was able to zoom in on a pic, but I will do that too to be sure. the pic is a bit fuzzy.

thx for quick response.

Does the polarity of the arc voltage signal matter?

I don't want to take the cover off again, and I can't see the wire colors in my pics.

re-did the strain relief on the high voltage lines....

Yeah, I'm glad its a help. I'm used to the Jeep world of 500 pics of every mod ever done, so its natural to post this stuff here. I imagine the C&CNC DTHC and PM45 are going to be a very common...

I've yet to see pics of this online....how about taking a look at my install so far?

First is accessing raw arc voltage. I found this to be easy and straightforward. Ground clamp is very easy to...

Hello - nice to see this Hypertherm forum up, i'm a repeat customer having purchased a Powermax45 after being pleased with a 380 for a few years now.

I'm installing the C&Cnc DTHC in a powermax45...
