Newbie - are "exclusion zones" a thing? was created by rthorntn
Hi,
I have only a tiny amount of travel on my 6040 CNC (~63mm) and I'm new to this all.
I'm trying to get my head around how I keep my end-mill from crashing into stuff, for example, clamp parts jutting out above the workpiece (like star & wing nuts).
I've watched a shopbot video about "Safe Z Pull Up" and I'm aware that there is a "Safe Z" in Cut2D, is that all I use?
Also I'm half considering putting a semi-permanent 35mm high touch-off plate in one of the corners, if I was to do that then its unlikely that "Safe Z" would help, especially with a 30mm long end-mill?
What would the best practices be on LCNC?
Thanks.
Richard

Fixture avoidance is really a CAM thing, All the controller knows and cares about are the axis/joint limits.
But if you really, really wanted to you could probably come up with a custom solution in a hal component that combines the current tool length and the X,Y,Z coordinates and then acts accordingly when a program is running. That is the beauty of LinuxCNC.
