General Mach Discussion / Mach 3 shifts the toolpath to the left after 3minutes of cutting? Parts overlap!

« on: November 07, 2009, 05:18:17 PM »

Hi,

this is my problem:
I make a G code with lazycam (tried both new and older version, does not solve the problem).
Import it into mach3.
It runs fine for 2-3 minutes.
After this, always at the same part, mach 3 shifts all of the parts to the left (see image).
this:

becomes this:

I have no idea why.
When I import the G code in mach is looks allright on the toolpath viewer, but when it runs it, it goes wrong.
Anyone can help me please?
Thank you

General Mach Discussion / mach 3 worked on XP, but won't work on 2000 (older, other pc)

Hello,

Ik have used the demo of mach 3 a while to do some test with my first cnc made of wood. Now that I know that it works, I am building a second cnc which is more expensive, more accurate,...
I used mach 3 on a pc with windows XP intalled standard on it and it worked fine.

Unfortunately, that pc is needed by someone else, so I am forced to use another one. So it took an old pc with windows 98 standard on it and putted windows 2000 on it.
Mach 3 runs on it after running the "special driver", but it won't move the steppers. The configuration in pins and ports is exactly the same as the pc I had before (the one with XP).
There is nothing wrong with te electronics (I just tested them with the XP pc and worked fine with mach 3).
Already checked the device manager and port is located on 0378.
I like mach 3, it is simple and works well, but I do want it to run on the old computer first before I might purchase the license file in the future.
Can someone help me please?

Thank you

Mathias
