I trying to cut a simple bracket out of aluminum. I am using a shapeoko 3 with the carbide motion and a .25" end mill. Since the first pass broke my end mill, I've been trying to go slow
The pass depth is set to 0.010. In the simulation it does a fine job. When I make the gcode file and put it on my router, the first pass is 0.250" deep. I zero'd it manually and also used the fancy probe. I made a new file from scratch and it did the same thing. I made other files (simpler) and they behaved as I expected. I am confused> can someone please tell me what I am doing wrong.
P.S. Can someone recommend a good gcode reference book? I've programmed in ASM, C and C++ for decades, so would just to like decode the gcode.
