Ok i am including the photo carve file i created but basically i have found the following.
Try to set angle of cut at 20 degrees approx to the grain of the cut, if you want a 45 degree angle rotate the wood a little on your cutting bed.
I get all my ply free from a forme maker and i then apply 2 - 3 coats of clear varnish with a steel wool sanding in between each coat.
On the pic of my rottie above i used the following settings.
Material size 300 wide x 200 high 9mm thick ply
60 degree engraving bit (thats a 30 degree side angle) i got caught out and was inputing a 60 degree bit as a 60 degree angle after noticing in the tool screen that the angle was a side angle and not overall angle like a v bit i changed it in my settings)
Ok back to the bit, 60 degree 0.1mm tip 3mm shaft
My feed i have not even really looked at but it is set to 50mm/sec and 12000 rpm i have my kress set to no 3 which is approx 12500rpm
My max depth is .8mm (sorry no imperial unles over an inch)
I have the line spacing at 114% that equates to a 1.168mm line spacing gap., i have gone to under 1mm gap in ply but then use a 40degree bit.
Like i say the thing i found to better my results was purley grain direction and the engraving angle.
I then cut the item and after cutting i drop the z axis by 0.1mm and re run the cut this cleans any bits out of the grooves.
At this point whilst still bolted to machine i add my boot wax, straight from the tin using one of the brushes for polishing shoes, i make sure all lines are filled then wipe of excess, it will leave a staining effect to the varnish but i then give it a light sand to take top layer of varnish off.
Hope this ends up usefull to someone.
Unfortunatley the file is 5.08meg so cannot upload it if anyone would like it then PM me.
