Yes. I've had boards similar to the Sanguinololu quoted at $15 shipped, fully assembled without microcontroller. That's like a quarter of what they go for on eBay.

sorry, that's kind of the point I was making.

if you're going to a wholesaler, then you're thinking of buying pre-made boards either black circuit boards to sell, or fully populated boards?

surely it's cheaper to go to a fab house and get the boards made given that the designs are freely available anyway and cut out the wholesaler.

Cost me $27 shipped. Although I would probably design mine a little differently.

OK Well I saw the Sanoglou boards on ebay come form China and I assume the steppers motors. ( I am in Global Sourcing and we have a new China office in Shanghai now) I want to confirm and see if I can get the parts their for less of course. I would suspect so probably 50-70% less

So do you know the part/model of the board, steppers, extruder? Are their upgrades ones that might work? I can find and source them and probably even visit the suppliers.

Pellets, good idea.

would it really be any cheaper to buy boards from china than it would be to just download the schematic from the reprap website and send out and have the board manufactured?

All the CNC machines use ball screws which are apparently super accurate but I don't know enough about them to know if they could be adapted.

I think an upgrade kit from you or Solidoodle for a precision z system would be a winner.

upgraded PCB
Steeper
Dual extruder.

Now I would consider packaging an upgrade kit if it is a good deal for all parties smile

I saw PCB boards for $10 on ebay so if I am there I might just load up on few spare motors, pcb, etc for my unit and for other as just in case.
