Can you post your NC file so I can see if you’re using the correct post processor.
Send me a little file of something I can run to see if its my programing that’s the problem.
Yes the back lash is high. That’s why I reduced the pierce and cut height and the torch is still running high, the pilot arc still touches the plate though.
I was looking around on the forum site, I’ve posted some test code a few times but I just can’t seem to find it and I’m not in front of my computer currently.
Anyone else out there have a square with a circle in a piece of test code they can post?

try this simple test square
2"x2" 1" hole at 100ipm .06 cut height .15 pierce height .6sec pierce delay
use smart voltage by setting the thc voltage to 0 volts
I am still suspect of the dry contact vs xfer connects ( jumper ) in the machine. These need to be in the dry contact position.
Page 53 of the manual can you take a picture of this location.
Clamp on material for sure!

Simple test square / still will not fire
Put in the jumper for xfer connect. fired and cut one piece. 
next one misfired, same crap 
reset misfire again This happened two more times with letting the machine time to full reset (air blow down)
Now reset misfire/ reset misfire/ reset misfire/reset fire run program??? all from the pierce start position as fast as I could reset and hit start not giving the cutter time to reset (blow down)
Move to the next cut same thing.
This is baffling. I have got more action with the jumper installed that’s good.

Could you screenshot your fire control as it would be before you start cutting.
Also maybe a picture of where you’re making these connections inside your hypertherm and that jumper wire area.
I would really like to see you try another plasma cutter on that setup if possible. I feel like the okay to move function built into the hypertherm maybe causing some issues.
If you had a another plasma to try we could at least know if it’s your hypertherm or the langmuir definitively.
I may have found the problem in the cutter its self. I am in process of running tests per the service manual. Seems I have a voltage discrepancy between C94 and C98 capacitors. It may warrant a resistor replacement. I need somebody to fire the torch wile I check voltages.
My friend has a new powermax 65 that I am going to borrow as soon as I get a hour to go get it.

Just got off the phone with Hypertherm tech They don’t feel there is anything wrong with the cutter. and to look into the THC control,
Once you try your friends 65 you’ll know right away if that’s the case.
So true, but if that doesn’t work then what? I am going to get this afternoon.
Are you going to hook up the 65 for raw voltage or divided voltage(if it has a CPC port)?
Sorry we were both mislead 
It is a new machine but it is only a XP30 and no CPC port And I am not about to open up somebody’s new machine that’s not mine to wire up on this table. I’ll have to find another one somewhere else.
I wish I was near you I would drive over and help.
What area are you in ? maybe there’s a a member around that could come by.

Thanks for the offer but I am clear over in Western Pennsylvania in Notown no jobs/ no opportunity’s /no future /no life.
Reading through this. Didn’t catch the answer
Post processer? just the one in Fusion.
Thermal dynamics variant??
Did you say you did download from Langmuir’s website their post processor for Fusion or no? There are two. One is with Z-Axis Upgrade and one without.
Z axis up grade
