Hi All,
I realise this is more a machining issue but I've been stuck for a long while without
a solution.
In Moi I made made several small discs with a pattern to be cut in brass with a Carbide 3D Nomad 3 cnc.
I made a jig but even if I cut just one piece on its own, the problem persists.
For the pattern, I run a toolpath using Carbide 3D's diamond drag tool called the Mcetcher.
Then, I run a simple contour toolpath with a 1mm end mill to cut out the disc. The brass
plate stays in exactly the same place in the jig and has no wiggle room at all.
To ensure this I use the super glue/painters tape solution.
The problem is either the pattern or the contour toolpath doesn’t
cut in exactly the correct place… it’s off centre, leaving a border on one side
and none on the other. Here are some test samples:
And here are some pics of the small inconsistencies of each circular cut:

This happens whether I cut one disc on it's own (without the jig) or several at a time (with jig). It
also happens if I cut on acrylic or mdf.
I've been in touch with their support for the last month and half, but have not
had a solution yet.
I exported the .3dm file as a dxf and imported into Carbide Create which is Carbide 3D's software.
Would anyone have any input that could solve this problem?
Many thanks,
Gunter
