Hi Ron-
I have tried to make a rectangle pocket and a circle pocket (first cuts I have ever made on new DIY mill). The rectangle was supposed to be 5" by 1" with the origin at X=2.5" and y=-0.5". The circle was supposed to be 1" in diameter.
The circle came out correctly sized and located. The rectangle was correctly located, but was too long (5.13") and wide (1.14"). I set this up for a 5/16" end mill and have made certain that this was the end mill that was used.
At first, i thought this may have something to do with "cutter compensation", based on my cursory knowledge of these G codes. After looking at the code, I do not think this is the problem (can't find these codes in the NFS mill wizard output).
I append the NFS output below.
As this is truly my very first attempt to machine anything, I expect I am doing something wrong....
thx for any help,
best,
jake
