Brilliant work, you have most certainly put the doubting Thomases in there place.

Thanks Pal, that's what I thought, didn't know if perhaps the new version may have added something, like Repetier has.

can matter control be used to run a CNC machine.

Well, wonders never cease, reloaded the file this morning, and it printed fine, so it has got me baffled.
I use Matter control V1.75

All of a sudden the printer is playing up.
everything is being delayed, all movements , when I press a movement button there is quite a delay before it moves.
during heating it take quite some time before it registers a change.
While printing it moves, stops for a few seconds then starts again.
Any help here would be highly appreciated.

Can't really help with other brands, I find the one available that works for me and stick with it.
Not one for experimenting.

Its one available here in Ausland it's by a Chinese company Sunlu, not sure how well known it is, but it works well, it's what I used to print the parts when I rebuilt the printer.

I tried the petg at 230 today and the improvement on the outcome of the print was quite amazing, so for me this seems to be the ultimate.
At 235 I found it was dropping lumps on occasions which was causing the axis to jump and it was very stringy.
So maybe the Chiron is the correct one.

In general, I print PLA at 195-200 and PetG at 225-235, with good results at either settings.

I had a problem with the export as well, it only exported half the file.
So I have reverted back to V1.75 once again, for me it is far more reliable, and must easier to use and find things.
