stepper driver:
first choice: gecko G540
alternative: gecko G251
for such a small machine, use TB6560 3axis board for 60Dollars, instead

spindle, motor
proxxon IB/E for the motor
proxxon IB/E > wolfgang

motor mount:
for the proxxon IB/E, the mount is a 20mm hole in your tool clamp

power supply: old pc psu will not be good enough, need a better one
relevant notes from #linuxcnc
12:19 < archivist> I picked an old Lambda 24v 20A psu, was adjustable to
moved it up to 28v
12:19 < sirhoax> yes my 12v psu drops voltage.
12:19 < sirhoax> cnc moves way to slow.
12:20 < sirhoax> nemic lambda makes good psu's
12:20 < sirhoax> got one here for electroplating
12:20 < sirhoax> 5v@120a.
12:21 < archivist> psu on right

12:21 < ManMower> I don't think it'd do any harm to test drive it with a pc

stepper motor is built into the sable stepper motor:
epson Astron steppers
