General Mach Discussion / help...cutting text (letter) on plasma cutter
« on: December 18, 2009, 02:56:05 PM »
Help

I am cutting text (letters) on a plasma cutter and I cannot seem to get the letters to run smooth expecially the the rounded letters like S.  the machine shakes. the letters have an extreme amount of points.  I have tried corel draw, illustrator, importing them in auto cad, rhino, sheet cam, then to Mach to cut.  I have tried using the letters plain, making them into outlines first.  Nothing that I have tried seems to work all of the time.

« on: December 02, 2009, 09:43:08 AM »
A few times when I reinstalled Mach,
then re-configured the ports, pins and general config.
After, I cannot get the motor tuning to work.  Any ideas??
I appreciate it.

General Mach Discussion / cutting corners off while plasma cutting cv?
« on: November 20, 2009, 12:08:42 AM »
I just installed the newest stable release of mach 3, on my plasma cutter.
I also installed the newest tng sheet cam.
Now that my plasma cutter is up and running again, the corners of my letters seem rounded off.
the files all look fine even in mach, but the end product does not.
see picture. is this a cv setting problem or something else??
does any one have a tried and true screen shot of general configuration, that they would not mind sharing?
I am cutting at 250 in per min, i have a thc-300,
