I got it to work by choosing the finishing contour option instead.

I figure I would try posting here first due to all the SprutCAM users.
I am trying to vertically lathe something on the tormach which requires three different type of operations. The cutting tool is mounted in a vise vertically like in the picture.
1) trim off the OD. Workpiece is to the left of the tool (x coordinates are negative) and spindle is CCW. I got this part down by using another coordinate system that is in the same location as the global coordinate system, but rotated 180 degrees in the Z axis. Thus the x axis points the other way (note the red arrows).
2) bore out the ID with the same tool. Workpiece is to the right of the tool (x coordinate positive). Spindle is CW. This part is ok too.
3) I am stuck on this very last part. I now want to trim away at that little green highlighted section (job assignment) by having the workpiece to the left again and spindle CCW. However, sprutcam won't move the tool to the inside and would rather trim away at the outside edge as shown in the picture. What's up with that?

I'd love to see a pic of the part when you are done!

Sorry, I did not see your post until much later. I already finished the pieces, but here is a picture of what the setup looks like:
The piece has really thin walls, so I used a backing plate and a ring which supports it against the spindle.
This is what is looks like on the inside. That little step near the center was what I was originally asking about. The majority of the boring is done with the tool towards the left side and the spindle CW. To hit this little step, I had to move the tool to the right side and spin CCW.
It wouldn't have been possible to do if I wasn't able to get chip breaking, coz that would have resulted in a big tangled mess. Fortunately, if you feed aggressively enough you get a big hot spray of these little curly chips. I only got a bit of tangled mess on the light finish pass.
Man, that is incredible. Very nice work... Im super impressed you were able to make a part of that size using the vertical lathe process on the tormach. The finish looks beautiful.
Can you talk about how you were able to get a part of that size mounted to the spindle?
My mind is spinning on what I could make... if I could figure out using sprutcam for a verticle lathe.
Do you use the standard mill post processor or something different?

It's basically an arbor system with a snug slip fit. I made this on a manual lathe, as well as pre-boring out a hole in the workpiece for the arbor to fit in.
I used the Vertical Lathe postprocessor from Tormach.
Beanbag, were did you obtain the vertical lathe postprocessor for the Tormach 1100 from? I would like to have this postprocessor, but after cheching the download site at tormach I'm unable to locate it. I see the ones for the duality lathe but that's it as far as lathes are concerned. would you shar with me where I can get it. Thanks, emc3zach
email tormach then
Ok, I'll do that. So I will assume that you got the postprocessor from Tormach.
Thanks, emc3zach
