Problem, Mach3 or computer???
« on: January 30, 2010, 10:32:23 AM »
Hi all,

I was cutting a guitar body out of a test blank of pine when I turned the blank over after cutting the back, it was running the contour cleanup and it turned right and plowed into the body ruining my day and the blank.

I checked the gcode and didn't see anything wrong. So I wnet over that spot cutting air and it didn't do it. The only error I saw in Mach was the feed rate red light was blinking. It stopped moving. The .5 endmill was about 1.5" down when it happened.

I have no idea how to troubleshoot this, other than throw another blank on there and let er rip again.

Any ideas?

Here it is cutting the back. http://www.youtube.com/watch?v=ra4amnO6L8g

What are the specs of the computer?
What rev of Mach?
Do you use the computer for anything else other than Mach and were you doing anything with the computer at the time of the crash??

Thanks foir the reply. IT is a AMD64 with 1 gig ram. It is only used for Mach3. The latest version of Mach3. I wasn't doing anything on the computer when it happened. I never do when it is cutting. I only use this machine for the cnc machine. I have turned off updating and all the extra crap.

Did it move in the wrong direction, or did the Z axis not lift up?

It moved in the wrong direction. It was cutting the contour and should have continued around as far as I can see. I could go check it now but I didn't write down where it happened so I can't check it now.

Did the tool path display show the wrong move?

If the g-code is correct, then I really don't have an answer for you.

Yeah, the gcode is correct. I checked it, and I ran that area cutting air and it didn't do it.

I am thinking it is computer related.
I am going to throw a 3.2 ghz with 2 gig ram and see what it does.
