I am thinking about getting a Tormach 1100 within the next 6 months or so I have downloaded Sprutcam 9 first as I have no cnc experience and of course all the utube video's are version 7 & 8. I have no problem with the end mills and it machines fine but I can't seem to get the cursor to highlight any holes for drilling or pick lines any ideas what I am doing wrong? Another problem is when I run in inches the simulated machine is really small the part is huge in comparison generating colisions when run, in mm the machine is normal size and works fine does sprutcam run in inches or is there a box I have to check off? I have tried it using viacad and 123d.
