Hello all, I am a new user of FreeCad but an experienced machinist who has always written G Code manually from engineering drawings. This is possibly not a problem but it is unexpected G Code behavior when using Step Over in a Pocket. I have different feed rates for Horizontal and Vertical, when Z moves it obeys the Vertical feed rate as expected, X and Y cuts in G1 / G2 / G3 obey the Horizontal feed rate but with one exception. When making a Horizontal G1 move for the Step Over it uses the Vertical feed rate. This seems to be repeatable regardless of tool size, step over percentage etc. I have attached a very simple FC file and the G Code output along with a screen shot, H feed = 6mm/s V feed = 3mm/s (F360 & F180 in the output file) I added some comments where the F180 is used. I have modified the basic grbl_post.py to format the output for easier reading so have attached it here also. Any pointers to what I have done wrong or an explanation of why this is correct would be much appreciated. Thanks.
