Anyone use Centroid 4th axis?

[Anonymous]

Has anyone had success with using a 4th axis post processor for use with a Centroid CNC? I looked around here a little bit and it seems that no one has been able to make that work if they are using Fusion 360. I saw a Centroid post processor in the Fusion library, but it does not have A axis capability.

I use a Centroid with a post I modified for 4th axis, however I have only used it for 3+1 machining. If you are looking to do 4th axis simultaneous i have not tested it.

The only post I currently use with 4th axis is the Fanuc post with A axis and inverse time. I have no idea if that would work on a Centroid 400m control or not. I would likely use indexed 4th axis on my mill for sake of allowing the machine to be more hands off and help eliminate extra part flips. 

I am looking to have my mill retrofitted with a 400m here in a couple weeks and I will need to have a 4th axis capable post is why I asked about it.

I have a functional post for at least 3+1 use (attached). It wasn't difficult to modify the centroid post to suit, although I did have to remove the axis locking (clamp) as my machine does not use a clamp (although it likely should to prevent unnecessary wear on the rotary)

Makes sense. My 4th axis was cobbled together from a rotary table and a spare servo, so I don't have a brake either. It will be a couple weeks before i get my mill retrofitted.

I do have this .f3d file that you could try to see if simultaneous 4th axis will work. It uses the "flow" cycle from Fusion CAM side.
