Hello
I have try to run a simple programm on Mach3 with G3 and Incremetle I and J. Unfortunaly i have not find a way to use incrementle I and J interpolation.
I have also set the IJ Mode to Inc in General Config.
Can someone tel me wath im done wrong?

If your code is not working then you did not apply the I J correctly. the proper code is entirely up to you as Mach3 cannot read your mind or write your code for you.

Hello
In the toolpath the red lines shows the way i would like to run the machine. But if i start the program, the green line shows something completely different.
Watch can be the reason for this difference?

Its hard to tell, but is that an arc in the ZX plane, if so then you need to use a G18 and then use I & K in the G03 line.

No, my goal is to cut in YX plane with IJ and G17. I have try with G90.1 and G91.1 with the diffrent values for IJ. This is only a simple example. I have the problem with all G3 Codes. The only G3 i have successful cut is a exact half circular.
I can not find the reason for the big difference between the red lines, thad comes up wen i load the program and the green line, thad is painting while the program runs.
If i run the full program, i get a full green circular for each G3 command.
Most of the program all three axes are move in minus area.

Hello
I have tried something:
The Problem i have explained is on a Win7 PC with CAD and CAM Software. The Mach3 is only for testing the cnc program, without any configuration or connection.
Now i have loade some of the program's, i have the problem's with explained on top, on a LapTop with WinXP and configured connection to a CNC maschine.
The program seams to work exactly?!?
Now i wonder what i must configure on the Mach3 installation, on the PC without a connection to a real CNC?
Thanks
