Repeat cycle

just to add to your confusion, you can also write cycles "defined shapes" using macro's (#<value1>) -u can do anything, once u can think programs up in algebra!

by the way, usually radius compensation issues are to do with where your start and end points are, tis usually good practice to extend the toolpath before and beyond the finished shape you need to allow the tool to move into correct position when rad comp is turned on, and finish the shape u are after when it is turned off.

Your g code runs fine and is doing exactly what you programed it to do, but I think your a bit confused as to how to start the lead in move for the smaller triangles. A proper start for an inside profile would be in the middle of a line with an arc move and progressing CCW around the profile and overlapping the start point and exit with an arc. This assumes you are using normal end mills and not backwards ones.

I'm a little bit confusing about G54 and G55, I must read some more.

Try linuxcnc.org/docs/html/gcode_coordinates.html

Have you checked that you have the proper lead in move?



"G41 start cutter radius compensation to the left of the programmed line as viewed from the positive end of the axis perpendicular to the plane.

G42 start cutter radius compensation to the right of the programmed line as viewed from the positive end of the axis perpendicular to the plane.

The lead in move must be at least as long as the tool radius and can be a rapid move."

Sorry to duplicate, did not see John's answer before posting....

Thanks a lot!

I assume that my problem is definetely the lead in move.

I can't test it today, but I will share my results as fast as possible.

Have a nice day
