Thoughts on how to get past the z repeatability limits - #15 by Robthatguy
I listed some of my feeds and speeds. Just some extra info for you to take a look at. Alot of people use different feeds and speeds styles so you may end up with 3 or 4 different suggestions.
This image and video here was cut at 3690 adaptive .15mm doc 1.27 optimal load ( pretty agressive for the nomad) with toned down feeds for a finish. I was worried about a working part more so then surface finish.
Its important with the nomad to do a rough, finish and a spring pass. Small machines like this have alot of deflection to fight with.
