I found just a single post that was even remotely related and did not find a solution. Trying to run a tool to a corner whose radius will be the same as the tool but I get this error. If I re-write the program and offset the tool manually it runs fine. Trying to do this with G41 or 41.1 sample programs.

This is written with .375 tool offset manually. Runs fine.

What error?

If it is about gouging, have you read this post?

Straight traverse in concave corner. The rest, in case there are more errors that begin the same, cannot be reached by the tool without gouging.
Thought that was pretty plain.

I looked at the mentioned page and that doesn't solve the problem either. I tried substituting a .250 end mill instead of .375 and the same error.
That post is doing holes, I am simply moving from one point to another and then making a 90 degree turn.

Also tried from the tool file, put a .250 in tool 1 then changed from G41.1 D0.375 to G41 D1 still the same error. I found the problem, I was entering G41 before my rapid move to start position. Moving that line down below Z-0.063 and the program runs.
