Thanks for the response. I realized that with the demo version of V Carve, I can't upload the post processor. I want to see if something could get cut out using this software. I tried loading the .nc file but there are no parts listed on the controller. I don't know if this is possible, but if someone could send me a small .nc toolpath file with the edited post processor that would work with a CS43 that would be really helpful. That way I could dry run the file on the CNC. Again, I just want to see if the machine will run something because I am looking to purchase V Carve.
