Hi Uwe, I've managed to create the part that I mentioned earlier. My headstock doesn't seem to have any noticeable play, but I had to put some feeler gauges under the front of my tool post to stop it from diving down a bit when cutting - this lowers the centre height of my grooving tool.
I think my bedways are fairly well adjusted, the main issue is the diving toolpost that I mentioned earlier. I'm not really sure how to go about making it more rigid, I've attached some photos in case you have a good idea

Best way it to replace the compound slide with a solid piece cast iron and bolt your tool post firmly to the cast iron block.
No need for the compound slide with CNC.

This is the Profile cycle, Groove is only a comment

Section 8.12 (PG 104 in the latest manual) covers the groove cycle. F5 CAM/F1 Intercon/F3 Insert/F8 Groove.
Uwe's program images that you posted in your Query are not the Intercon groove cycle, but a profile cycle. The standard groove cycle cannot create the angled sides nor the radiused transitions.
Learning to use the profile cycle is one of the most beneficial things you can do. It can do everything the turning, facing, grooving, and boring cycles can and so much more!

My compound slide is unused and I have tightened the slides up on the compound slide, so that there seems to be no movement at all in the compound slide. It is effectively just a block of cast iron already. I think the movement I am getting when parting, may be related to the post for the tool block.
When I bought the tool holder / block, I had to make the post for it, and I just made whatever seemed to do the job. The toolholder has to be able to turn in order to take advantage of more than one tool at a time. Perhaps you could suggest an alternative post for the tool block?
