Has anyone ran into this problem? I tried figuring this out thinking i made a bad DXF but i made a simple box and still same report? is this a sheet cam issue or is it something else entirely?
Is this your first attempt at cutting?
Did you 8mport and install the post processor into sheetcam from Langmuir?
Did you create a tool for plasma cutting in sheetcam with tool speed?
yea this is my first time cutting(or at least trying to),i downloaded the 1.6v on the website. i made a plasma tool on sheet cam and made sure that the post processor was the 1.6v, here is my gcode list

This is your culprit and probably means that you haven’t set up the tools properly in SheetCam. Take a screen capture of the Tool setting, the operation setting, and the job options screens.
Well your code is trying to use IHS and THC so some setting is wrong. Also, your cut speed in your first operation is 3.937 IPM even though your tools says to use 40IPM.
But the note says to set Pierce Height, AND Cut Height, AND Plunge rate to 0 to disable the IHS. You have these as non-zero values. Maybe that’s your problem. Also, you should check the box that says Reverse Cut direction for plasma cutting.

I’ve had my feed rate end up like that before when I tabbed through the fields without noticing. Check that all your units are set to inches throughout sheetcam.
so i made a new tool and that seemed to work, but now when i run the part i have a IHS fail, any reason why?
Probably should include @langmuirsystems in that question.
Did you set pierce, cut, and plunge to 0?
yes but it seems when i put plunge to 0 it will give me the error line 17, and if I give it a value when i run the program it will giv me the IHS failure. positive note i can run the program on a dry run… @langmuirsystems have anything on this?
You NEED to set the other values to zero as well, otherwise the Plunge value is used and will create an error.
Here is what im doing as of right now to clarify

Ok, on the tool update, did you click on the button that says “Update Operations”?
Probably not since the output still had pierce height, etc.
So, go back and edit EACH of your operations, which have the old tool settings, and edit the cut height and pierce height to 0. Or, better yet, dump this whole job and start it from scratch FIRST making sure your tool settings are correct.
So i restarted from scratch, same thing. Could it be my post processor? i downloaded the one without THC and IHS but i at a loss here
Dunno. You’re going to have to wait until someone from either LS or has the same setup as you can answer. One thing you can do is zip up your .job file and post it. Then someone with the same setup can see everything about your settings.
@langmuirsystems any help on this?
Can you do a test with just one operation with the pierce and cut height set to 0? Also be sure the post you are using isn’t showing ‘edited’- use v1.6 as downloaded.
What version of SheetCAM are you running?
