Inc Interpolation G91.1 not posible

« on: April 25, 2013, 04:14:49 PM » HelloI 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?Code:(<1: Programmanfang>)%1(Kommentar:Anschlag Seite Tasche)G17G40G50G80G90G91.1(<3: Werkzeug Flach 4>)M9T02 M6 (GUID:DD03DC72-ED4D-4566-8210-78C797258D9D)M8S20000 F1200 M3(<4: Kontur 2>)G0 X-50.367 Y5.449G0 Z2G0 Z0G1 Z2 F800G3 X-45 Y2 I5.367 J2.452 F1200G1 X5 Y2G3 X11.075 Y7.02 I0 J6.185G0 Z2(<5: Kontur 4>)G0 X-50.367 Y5.449G0 Z2G0 Z1.5G1 Z4 F800G3 X-45 Y2 I5.367 J2.452 F1200G1 X5 Y2G3 X11.075 Y7.02 I0 J6.185G0 Z2(<6: Kontur 6>)G0 X-50.367 Y5.449G0 Z2G0 Z3.5G1 Z6 F800G3 X-45 Y2 I5.367 J2.452 F1200G1 X5 Y2G3 X11.075 Y7.02 I0 J6.185G0 Z2(<7: Kontur 8>)G0 X-50.367 Y5.449G0 Z2G0 Z5.5G1 Z8 F800G3 X-45 Y2 I5.367 J2.452 F1200G1 X5 Y2G3 X11.075 Y7.02 I0 J6.185G0 Z2 Logged

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. Logged

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 Logged
