I am trying to cut a 1" hole .500 deep in a 2" x 2" x 1" alum block using a 3/16 flat endmill. I drew the part in rhino and imported it into feature cam to generate the g code. I load the g-code in mach3 and when i run the code the z goes up about 2" and moves to the center of the hole and starts going down and stops about 1" from the block and starts to cut out the hole. I have all the offsets set to 0 and im starting off at 0. I am using a post processor i downloaded off the net and im sure i need to work on it a bit. I am running a Taig with geco drives 201's and featurecam 12. If anyone has a post for featurecam it would be most appreciated.
Here is the first bit of g-code.
