LinuxCNC seems to make cambam nc way too big

Hello,
I'm french so excuse my english please...
I'm new to the forum though I bought my CNC seven years ago. I never used it as I should but lately, I've been trying to figure it out. And sadly for me, it just won't work...

I got a Telecast body in Cambam (the program that came with my CNC machine). I created a Gcode and when I took it to my LinuxCNC to have it made, the CNC just got crazy.
Why?
Because my 42cm or so turned out to be transformed in 13m long body...

I sent a request to the cambam forum where some more expert people than me said the Gcode is fine. So the trouble, according to them, is LinuxCNC that just don't convert metric-inch or inch-metric stuff...

Do you have an idea? I just don't know what to do and I hope someone there coud help...

Thanks in advance

I'm attaching the two files, cambam and NC in case...

Best regards

PS it seems that the forum doesn't let me join the CB file, nor the NC... I tried 3 times and it seems that it just can't upload it... So I'm adding pics instead... I don't know how you could test it (maybe adding it as a ZIP?) but maybe you could get an idea and help me. Thanks in advance once again...

Dear Aciera,

I'm sorry but I'm not good enough in the use of the CNC to understand what you mean by "do a move in MDI like G0 x 100" and I'm rather unable to do it.
If it helps my purpose, the problem is with that file, that I've reworked from a dxf.
Before that Tele, I made some inlay work (cutting mother of pearl for my logo) or cutting wood for a trussrod cover, and it worked fine. So I guess that the machine moved fine...

Here's the Cambam and Nc code in zip just in case...

Thanks for your fast answer anyway!!!! .

Dear tommylight, thanks a lot for that answer but...

Would you mind please explain the steps to make it please? That'd be great...

Cheers

Dear Aciera,

Here we go...

I opened the "ma machine file" and just saw a line "linear units = mm". It seems that it's already in mm (and not in inches)... So...
As it's 9 PM here in France, I will probably not read your post this evening, or later as wife call for dinner...
Thanks in advance!!!
Cheers

Dear andypugh,

If you see something like this it's just because I tried once to make the CNC running. It went crazy. I stopped iit in a hurry, maybe made a picture... Tried again and then came back to Cambam to try to find out what was happening. Then I created a new NC program, tried again and had the same error. Then I took another picture thinking that i was a problem with Cambam (and went to search advice on the Cambam forum)... They told me that it was probably the Linux...
It was really something like that about the pictures so maybe its not completely "picture one" going with "picture 2 or 3" but I have now only one NC and that Cambam...
