G-code error

Just recently started to pick up this error message.
I load the initial code and it works fine, after completed job load next job or ngc file and this error appears.
Coordinates disappear from screen and I have to reload axis to load another file then cycle repeats.

Does nobody know what the cause of this error is?
It's peeing me off now and only started since I played with NativeCam .
It don't matter what I do I can't clear it, I even went back to the old Wheezy 7 I had on dvd and installed from that.

Hi Tom, scan is just an engraving pattern, it doesn't matter which ngc file i try to use its just not having it.
I have to load the file before homing, once a home button is pushed it won't let me load a different file.
I then need to restart axis and load a file before homing. There is nothing in the G-code to create this.

Research seems to point at the [RS274NGC] but there is little to research on Google.
I have installed Jessie 8 this morning and downloaded from the Buildbot a new lcnc uspace setup my mill with stepcof wizard and generated a fresh engrave ngc with F-engrave and still get the same error.

I am not doing anything different to what I have always done and it happens now on all my computers even the simulated laptop which has a git clone lcnc, stretch 9 and 4.9.0-2 rt.
It only started recently and won't relent.

I am seeing a similar error with 2.8.0-pre1-3126-gcb74ca8

After running a few NGCGUI routines then i get a error about an m31 code - sometimes different numbers show up.
After than the back plot no longer shows

If i exit Axis/LinuxCNC and re-run the last command - it works with no errors.

Smells like a memory leak or something similar...

I have uploaded one of my crappy attempts at filming the error.
Not very good but you might see the problem and hopefully give a solution.

Thanks for trying Tom.

I know there is nothing wrong with either the ini fie or the ngc file they are the same as I always use.
Microsoft, refuse to use any of their software, won't have it in the house so no to that question.

This error has only come about since I was playing with that NativeCam I am sure it can't be related but I also don't believe it's coincidence.

It can't be that because I have completely wiped and zeroed the ssd and reinstalled yet again to no avail.

I did notice some of the git files have recently been updated and wonder if there is a newly built bug to report.
Has anyone else updated or installed in the last few days?

I was a tester of their products from win 95 to 8.1 and forced to use it at work so I know how bad it is.
Never allowed it in the home in all that time, Unix / Linux only.

I no longer work in that industry and wow what a release it is.

My grandson has a project of an old arcade machine to build and asked for help with it.
We are using a raspberry pi running Linux with a dos box for the games, he loves it, learning new skills and it brings back memories not all good ones and confusing where to put a capitol letter and which way the slash goes etc but we are there with it.
Bloody addictive these space invaders and Pacman.

To get back to the subject, I get a different M number with every file but it's always line 0 so something is looking in the wrong place to complete its task.

My answer to everything is to wipe off and start again which I have now done several times and still get the same result.
Leading me to be convinced it's not me but the system is failing.
