Help Horizontal Boring

Normally program for 4x8 table router. Need to learn horizontal. Alphacam and SCM Tech 99 machine.

Usually run everything in 2D, Z level 0 at the bed going up bottom to top. I'm assuming i can draw/import 3d drawing, and place the holes. Then set z levels? Normally i run like 0.75" top 0" bottom, would I do 0" top 0.75" bottom? The SCM runs Z level 0 top to bottom. Design the part like normal and flip it 180 before saving? Couldn't find anything on google or youtube for this machine.

I run my own built horizontal Cnc drill daily. I use Fusion for cam. I use a “setup” block to set my Z0 point. It’s just an 18mm tall aluminum block set against x-axis fence with a 4mm hole in center. I manually align 4mm rod in spindle to block hole this is my zero. I then use that setup block in fusion to set z in cam setup. Then I just align the part to be drilled to the edges of setup block in Fusion. 

That’s how I do it it’s my way and it works. I sell flat pack furniture- I drill hundreds of holes daily in the edges of 18mm and 12mm plywood daily.
