Hi, lazimolur

Don't really now what your trying to do, Trying to cut slots and testing tool & fixture offset's or just cutting slot's ?

These post's really should be in "G-Code, CAD, and CAM discussions".

A word or two would help, The M40 in the code is used for probing in Mach, What are your tool & Fixture setting's ?

Is it that the G40 isn't canceling the tool cutter radius compensation ?

Let us now, Chip

Hi,

There must be a line but the motion is like in the picture. There is no tool offset (Diameter of tool is 0) and also I don't use G41 or G42.

m40 script is
DoOemButton(235)

The lines are 0.7mm
The drawing on the picture is for showing the actual motion. But the programmed motion is only a line.

Circles (on the drawing) are at the true positions. But after g1 z..., every motion g1 x... or g1 y... or g1 x..y..  motions are like 0.2mm to right w.r.t direction of the motion and line and  at the end 0.2mm left (back to the true position).

For example:
Initial position x=0,y=0,z=0
g1 z-15 => x=0,y=0,z-15
g1 x20 =>x=0,y=0.2,z-15  and x20,y=0.2,z-15 and x=20,y=0,z=-15
g1 y20 =>x=20.2,y=0,z-15 and x=20.2,y=20,z-15 and x=20,y=20,z=-15
g1 x0 y0 => x=19.9,y=20.1,z-15 and x=-0.1,y=0.1,z=-15 and x=0,y=0,z=-15

There is no tool offset, there is no G41,G42 command.
