G-Code help, 4th axis

? I have no idea what your problem is from, but i noticed your using g56 g57, and one g59?

plus your numbers dont look uniform?

Looks like your going on an angle? But like I said, I don't know what your doing from the post.

I'm trying to make a CAM. 3" OD pc of steel, with a 3/4" wide slot, .5 deep. I figured I could use an undersized endmill (.611 tbe) and post out a path for center, left and right.. It didn't work as expected. Its on size on some of the path, but small on other parts. I guess the A axis needs to be shifted to compensate for the smaller cutter, but how can I figure out what needs to be done? All I have is point to point on the degrees so the controller doesn't have to figure anything out.. I always run into problems with getting the controller to use cuttercomp with A axis movement.. So I try to stay away from it as much as possible.

TIA

g57,58 and 59 are all the same values, I did that incase I had to make a small adjustment between the three paths.

Yea, thats probably the problem, I'm using a customer supplied cam path and when I was looking at it closer last night, I saw the same thing you saw. I have an onsize .75 cutter coming in today, I'll just use the 5/8 undersize to rough it out.

It does, after it reaches Z-.5 it leads into the part.
