thanks for reply , that’s sort of the way i was thinking,
eventually i did work out why i couldn’t get my trial file to look right
threw it into creality print , file had some really little pieces sticking out the back and also poped up saying needed repair, once i deleted them repaired file and reloaded it into MM it previewed right
I found a couple of files with pheasants. I imported them into OrcaSlicer and repaired them. Then I imported them into MillMage and set up the relief carves. They look good in the MillMage preview. It’s too hot (103ºF+) to work in the garage now, so I’m not sure when I’ll get a change to run them on the LR4.
