You should definitely do more CNC videos. Your very clear and concise and you actually show all the steps which is great! You could even reach out to Tormach and see if they'd sponsor you, who knows you might just get that third tool holder ;)
Neat little project! Couple of things: for that scallop operation, use a ballnose or a bullnose endmill with a small radius. Makes for a much nicer surface with steps 5 times larger. On that adaptive on op 1, leave about 0.05mm of axial stock to leave, then clear it up with a flat toolpath using about 70% stepovers. That way the deflection of your tool doesn't leave those marks. From an aesthetics perspective that obviously doesn't matter too much with the red dot sitting on top, but if you zoom in the optic is now resting on a bunch of ridges instead of a flat surface due to that deflection. Lastly, I'd split op 2 into two separate setups, where you zero off of the excess parts for op 2 and then just do the facing down to the milled surfaces, so that x and y aren't that critical. Then touch off again on the milled faces for op 3.
Ohhh man, that SPETools endmill packaging is WAY too familiar. You use their 3 flute 1/4" ?? I've beaten that to hell and back, enough that I damaged my CNC router, but it's still working GREAT
Hey I really appreciated this video. Real world. I am looking at a 440 right now and I'm wondering -- how is your stand holding up? I'm thinking of making my own stand too since it's such a small mill, not sure the $1000 stand is justified (I'd rather put that towards the drawbar or tooling)

Looks good. One note: 3D adaptive isn’t meant for finishing. Leave 0.01 or so and then (for this kind of part) use horizontal to finish.

Nice presentation, thank you! I have a 440 on order now.
great idea, its definitly a lot of work to get good at using one, but its all worth it
i wish i had the money and space to upgreade to one as well 😢
All right im sold, buying one
Do you recall about how long the cycle time was on that one part? I know it was a year ago, just comparatively curious.

Appreciate your kind words - it's been holding up great, I would definitely recommend DIY as I think the $1000 for their stand isn't a great value.
@@SUPERMOTIVE appreciate you getting back to me. Agreed on the value proposition. Cheers! Happy CNCing!
do you use paid f360 software? or free?
Paid, however the hobbyist license retains pretty much all of the functionality I used in this video
Do u need air compressor to run this machine?
Depends on if you run a power draw bar. Without it no, with it yes
With my setup, no
