I upgraded to a Centroid acorn. I have some parts I removed during the conversion for sale.

Novakon rev 5.2 motherboard. $125

Ethernet Smooth Stepper rev 2 $100

Both for $200

$20 shipping each. If you buy both $20 total shipping.

I'm posting it here first in case someone wants original parts for their Torus Pro. If no one wants it I'm going to repost elsewhere because there may be some interest in the smooth stepper for other machines.
