somethings not quite right there. face operations should remove all of the top face of your stock. i reckon you have a geometry selected that you shouldnt for that toolpath. leaving it there potentially presents material to your next toolpath that it isnt expecting to be there. if its cutting into the middle of that stock expecting to cut at 7mm deep, with that extra material there that cut may be 8mm or more depending on how flat your stock is to start with.

yes I thought it was odd too, but I have found the correct setting

but here is where it gets frustrating, to cover the whole surface I need to select "Outer Loops" if I select "All Loops" it misses the middle bit out

the following 'tapered holes' was from a CAM that I made from a 3d drawing in Fusion, the simulation works perfectly in Fusion, however it fails on the CNC Router by making the holes too big - and I can see from the toolpath on the CNC Router where it has gone wrong (my red pointers)

what could cause this error?

Looks weird, I'd guess theres an issue with the geometry selected for the hole. What tool path strategy did you choose?

Adaptive - (is that what you mean by a strategy)?

Yes there will be a more appropriate toolpath like bore or something more suited to holes. I'm not Infront of a pc at the moment to advise definite terminology but try a different type of tool path.
