Tool changers are usually very troublesome on a real machine. You will have
to do some fancy engineering to get the proper tool that your material will
accept and still be able to convey it in and out of the spindle. This will
take a lot of experimenting.

I started with a broken drill bit and spent my time engineering the "toast".
This bread never saw a toaster. I hardened the bread on glass in a
microwave. Sometimes leaving it in the sun to dry. Painted it black to get
some contrast. Most think it is burnt toast, but it is really quite hard. I
also used sidewalk chaulk, candles, and cheese. I am glad someone is doing
some N/C machines.
You have a lot of great new gears. I am anxious to see how you apply them.

Looking forward to following your progress.
