Problem with G2 G3

[Piergiorgio Panzone]

Good morning,

I have an ECS2600 CNC (OLD) that reads GCODE when dxf2gcode generates the arcs G2/G3 I from I and J with wrong coordinates not absolute and I am in error in graphics how should I modify the postprocessor? Thanks and sorry for the English.

You need to change in the following area, refer to WIKI:

 

dxf2gcode / Wiki / Postprocessor Configuration (sourceforge.net)

 

    arc_int_cw = G2 X%XE Y%YE I%I J%J%nl

    arc_int_ccw = G3 X%XE Y%YE I%I J%J%nl

 

 

You may need to change the I and J values of the lines given above to the format your machine is expecting. Just check example programs which are working to know what your machine requires. The values starting with %will be exchanged by the numbers, refer to WIKI ….

 

 

"%I"
The distance between Start and Centre in X

"%-I"
The neg. dis. between Start and Centre in X

"%J"
The distance between Start and Centre in Y

"%-J"
The neg. dis. between Start and Centre in Y

"%XO"
The X Centre of an Arc

"%-XO"
The negative X Centre of an Arc

"%YO"
The Y Centre of an Arc

"%-YO"
The negative Y Centre of an Arc
