Using a Nomad 3, ive traditionally used a 112 endmill to picket out larger areas. im testing CCPro’s Rest Machining feature so im using a #102 bit for the first time.
Can anyone recommend the settings (stepover, depth, Plunge, etc) when butting brass? I tried the recommended settings but stopped the machine almost immediately because it seemed like it was set to cut too much at once, i didn want to damage the machine or bit
What were the recommended settings you’ve tried? I only ask because there are none in the carbide motion tool database, so I’m not sure what you’ve tried so far 
We have some videos on feeds and speeds for various materials, including brass at:
I’ll chuck up some brass today and give these a shot with a 102 today.
Generally folks would say to take the aluminum speeds (which looks like what we see here) and back off 15%-20%
That said, I’ve run brass at the (very conservative) aluminum setting quite a few times without backing off and had little issue.
I’m wondering if your issues stem from work holding or your specific flavour of brass 
I use a Saunders machine work modular vise for work holding, it’s rock solid. I also usually use a 274z for brass which feels like a better cut than the 102 and is recommended in the material Monday videos Will linked. (They are spendy though, you probably wouldn’t want to use a new one every time )
cool, thanks. let me know what you find. I use bolts and washers that hold it down to the baseplate on the machine.
