Hello, Being new to g-code and cnc I've been trying to learn the best way to think about the coordinate spaces and offsets etc (for a cnc mill).
I'm thinking I should use a *fixture* plate with alignment pins etc to mount to the table. Some kind of pallet plate to hold the work (plugs into fixture). My current thinking is that I would home x and y to the lower left of the table. For z I'd use a spacer block off the table to the end of the spindle. From there I'd use global offsets use a global offset (G92) to align to the fixture. From there I'm guessing one whould use the users-selectable coordinate systems to align to a theoretical x, and y starting point with some kind of z plane somehwere over the part. Tool tables looked kinda fancy so I was going to defer using them until I had a better mental foundation of the system, using some kind of programatic offsets instead. Any input appreciated. Thanks.
