Good to know So I can start thinking about it, what kind of things would you like to see covered?

the objective would be to produce gcode for a three axis mill

CAD produce a model that is probably 2.5 D
CAM set up the material and cutters then program the paths

#124

Sounds emminently doable! I’ll have a think about what we could make as a demo.

Andy, I have the basics of fusion 360 cad/cam down and it looks like you know Linux cnc. Can we get together and do a small test piece? Something simple with some facing so adaptive 2d and a finishing pass is what I’m thinking… I need to know the tool specifics and work holding etc but can pick that up from popping into the space.
Thoughts?

We can probably borrow a clamp fixture from the manual mill also…

I think the collets are mismatched.It says Unimat on the box and they don’t look the same as these : https://www.isel.com/en/collet-for-ufm-500.html

That would fit with Ara aka @recursion experience/findings

This video may provide some insight in to how some collets work
It is worth watching so you can see how they should be assembled and cared for

the current spindle motor is functional but not ideal if we are spending money I would recommend getting something more appropriate
better bearings
better tolerances
speed control (which is a big thing)
standardised collets
I could go on …

The existing spindle motor could be repurposed as a die grinder or more robust “dremel”

an example of what we could get

#135

Yeah I looked at some of those- are the China ones good enough quality? There are some nice German ones for just 4x the price… whats the best value?

#136

Thanks Howard, will have a closer look early next week!

Hi guys, just wanted to know if the cnc mill could be used with brass metal?

Cheers
