Happy Birthday, Justin!

Congrats
It's been a long while since I've had any lollipops on my endmills.
I just looked at some of my typical settings. I'm using 1/8" bits, < .039" (.99mm) depth of cut with a speed of 15" (381mm) / minute for most general cutting. For a 2mm bit with longer cuts I might dial back the depth to .03" (.75mm) or possibly a bit less (not a typical operation for me). I run the spindle at 14400 RPM for most milling operations. Drilling and thread milling is slower (5K - 12K RPM). YMMV
I have a mister with air, but I typically only use air.
I'm using these carbide single flute upcut bits:
They say for plastics, but someone had recommended them to me years ago and I haven't had issues since.
Good luck!

Agreed
The foxalien machine looks decent with linear rails which are needed for rigidity when machining metal. You'll definitely need a real spindle. I noticed they include a 65mm support, but you really should look for one that supports 80mm and an ER16 collet.
If you want to get fancy like @naamanf you could get one with an auto tool changer.
Have fun!

Does anybody have some they can spare?
Thanks

Agreed on the 32GB of RAM and 6GB of video memory. Also, some of the "more powerful" laptops are quite loud.

on semi are end of life/obsoleting the FQPF8N80C
https://www.mouser.co.uk/ProductDetail/onsemi-Fairchild/FQPF8N80C?qs=oLpdVludopqPPn1yJbx16Q%3D%3D
its used in the power supplies for the T2 (kgsshv) and the modern version of the blue Hawaii.
thank you again onsemi for obsoleting everything that is high voltage and/or audio related.
currently radio spares and digikey have stock
mouser has been out of stock for some time.
I'm not seeing this as obsolete on the OnSemi site (only on Mouser). Am I missing something?

That’s awesome!
I did something similar with my grandmother, dad and mom about ten years ago. I watch it all the timeThese family stories are priceless.

Nice work @simmconn
The current limiting with Q5 is not fast enough. Put a depletion mode mosfet CCS in front (left) of M6 (Vin). Similar to what Kevin did on the T2. You'll also see this on the Circlotron 900V supply. The golden reference supply is much more robust this way
Good luck!

That might be possible, but not optimal for me.
I might just have them made.

Thanks. I saw those and they won't do for what I need.

For the +/-15v supplies, the pad transistors do not need heat sinks.

For laser etching anodized aluminum, you typically only burn out the dye from the anodizing. Once you burn into the aluminum, it typically turns the aluminum brown.
Try using less power to see if you can get it a little whiter, but it looks very good.
