Sloping Z cut

Post by cncbobuk »

Hi all, I'm trying to cut sink drainer grooves in a worktop using a bullnose cutter and whilst I can manage to cut simple grooves I'd like to be able to make these slope slightly down toward the sink. I'm sure I can alter the G code to accomplish this but could someone help me out with the correct way to do this please. The part of the code which does the simple grooves is here
Many thanks

You are going to have to manually edit the program. It can be done when you post it in the editor. After that run the code through a separate code simulator like Camotics or NC-corrector to verify. Both are free and do a good job.
