hi everyone, im new to cnc'ing. i bought a machine a few days ago and have an stl file that i want to cut as a test to mess with settings and learn how to do this.
my problem is that when meshcam generates the g code and i run it in mach 3 the first thing it does is smashes my spindle down on the z axis, through the backing board into the t slot table and jams it up.
i have tried to run the code from the top and the bottom of stock and get the same result each time.
what i am doing is:
1) start machine and open mach 3
2) ref all home
3) auto zero tool
4) move the spindle along y/x to where i want to start
5) hit go
6) spindle fires up and then bam! its trying to destroy my machine by driving straight down.
can anyone look at my file and g code and tell me what i am doing wrong before i bust this machine?
thanks
