Hello All;

Hopefully someone can shed some light on my problem.

I run relief cut from Artcam. It takes from 3-8 hours to finish and towards the very end, when only few lines left to finish machine gets stuck. I tried changing orientation of a cut but didn't help.

Any help would be greatly appreciated.

Just a shot in the dark but it could be that your graphics card is struggling (as can happen with long Gcode programs). Try running your Gcode program with the ToolPath switched off (Diagnostics screen) and see if that cures the problem. If it does then perhaps upgrade your graphics card (more ram).

Thanks, will try that.
Just to be clear, it is not the PC that gets stuck, rather the table loses position and moves to some odd place.

Ahh - that's a different problem - I thought it was the PC that stopped.

Before going further could you please check with Licensing http://www.machsupport.com/contact-us/ to verify that you are using a genuine Mach3 license.

Tweakie.

Sure. How do I do that?

 I have sent you a PM to explain.

Go figure, machine came with the pirated license. I bought new license today under my name.
I'll let you know if this solved the issue on hand.

Purchasing new license didn't fix the issue.
Still, after 350,000+ lines of code, on the last few lines machine goes crazy.

Can you post the last portion of the code ?
Does other code run OK ?
Does it occur at a G0 move ?
Excessive heat at the drives ? motors ? (would be strangely coincidental)

It happens every time I run longer code. It doesn't matter if the code is 300,000 lines or 500,000 lines. It always happens on the very few last lines (less then a millimeter of final carving work).  Mach runs through the rest of the code, and goes on the first line as everything was done, but the machine will go left-right few centimeters forever. Sometimes it even gets stuck. But always losses XY position after this (Z is fine).

Here is the bottom part of the code:
