This one had a shitty one on the air feed.
Took it off as i have variable regulator on the compressor.

Going to look on eBay for a water tank with pressure feed inlet.

Here is an overview of my fog-less system and in video description are mentioned all major details so you can DIY one. A properly made one, i mean. Hope that helps you.

Any recommendations on bits for fillets?
Like a round over tool for routers.

Also looking for alternatives to something like the Haimer Universal 3D Sensor.

Was looking at Zeeflyboy's link to the TPA2 but need something soonish and cheaper :p

Does this look about right for this 3 flute roughing bit?

I have a feeling that 3000mm/s is too much. Gwizard is saying 1000mm/s.

1000/S ? Do you mean 1000mm/min

**JOGARA** · 21-04-2017

Doh

Of course :p

Also, not 100% on the 1mm and 2mm. Wanted the single flutes but having to wait. Might as well try these.

Really struggling with the feeds and speeds for this 3 flute roughing bit.

Works fine for a few seconds then starts to chatter.

Guessing it is also a cooling problem?
Got the mister blowing a lot of air on it, also tried with a bit of water but same problem.
