Bounty ! Get a free Smoothieboard v1 and Smoothieboard v2 in exchange for a PCB design :) Please reshare to your PCB-designing friends :)

I'm offering one v1 board and one v2 board ( when available ), to the person that will design the following PCB :
* One-sided PCB, can be CNC-milled at home ( like http://reprap.org/wiki/Gen7 )
* All components PTH, except for the microcontroller ( LPC1769 to run Smoothieware )
* Pololu sockets for 5 drivers
* USB connector
* SD card socket
* 6x Endstop inputs, 4x Thermistor inputs
* 4x Mosfet able to handle at least 12A with adequate connectors
* 2x fan controllers
* ATX PSU main power input
* Connectors for Reprapdiscount GLCD
* As compact as possible
* Must be Open-Hardware ( CERN OHL )

It's time we had a Smoothie-based CNC-millable PCB, for the hardcore DIYers :)

Please reshare, it'll help get this done :)
This is a RepRap controller electronics board designed to be do-it-yourselfable. Replication is what makes RepRap unique, so this is now extended to electronics. All Gen7 PCBs can be manufactured on a RepRap, on a general CNC milling machine, etched with the toner transfer method, ...

Has anyone tired a positioning system based on an inkjet printer style "opto stripe" (no idea what the correct terminology would be)? See an example in this video (@2:46 if the time code below doesn't work):

Seems cheap, fast and quiet!

Thanks everyone. If you're removing a stepper and it's driver the cost could be comparable or less. As Jeff says, the advantage is that the drive system will always try and get to the target, where as a stepper just skips. In the case where you can't get to the target your print is doomed either way, but at least with a closed loop you know about it. It mainly appeals to be because it's such a neat solution.

New printers to build!
 
Talos sources released!

Spartan - The Cartesian 3D printer/CNC platform

Tria Delta - The Delta 3D printer

Silphium - Laser engraver


The Delta and the Laser engraver are a work in progress and the drawings are not completed yet.

I'd appreciate it if you could share the word.

Is this my only option for getting some Smoothie hardware right now?
http://shop.uberclock.com/collections/smoothie/products/smoothieboard
Rev 1a boards at uberclock or roboseed are all I can find. 4x is probably all I need. Panucatt are out of stock too.
The Smoothie project is about creating an open source platform for controlling digital fabrication machines and to make that platform as useful to as many people, projects, and use cases as possible. Smoothie firmware can run : 3D printers Laser cutters CNC mills Other types of machines with minimal effort By combining all of the jobs into a single modular firmware Smoothie allows different communities that would otherwise be working apart to...

This is probably not news to a lot of you but, if you've never tried a 0.6mm (or I guess larger too) nozzle go and order one right now. Fat layers are awesome, prints are so fast! After spending a long time trying to print a large, for me, piece the 0.6mm solved all my first layer issues and the print looks great!. I need to try the 0.8mm now too, oh and my I "need" a Volcano too.

Some usable code is here:
https://github.com/chrisbrent/Smoothieware/tree/feature/due_panel
It assumes the Bed has a designator of "B". It's merge with the latest edge so if you're setup to build Smoothieware give it a try. I hooked mine up to the serial debug port.

First smoothie print! The poor RAMPS I left attached is feeling jealous.

Questions/Help  - 
 
I have a Marlin delta question. My Kossel Mini is printing well, except that everything is slightly too big. I'm trying to reduce the diagonal rod length using M665 and changing the L parameter, but nothing changes when I print. I have EEPROM enabled and I save it with M500 and can see the changes with M501 but the print comes out the same size. Anyone else seen this? Any idea? I'm thinking of trying Repetier but everything else is already tuned and I don't feel like starting all that again.

I've never trusted m500 or really seen it as a good way to maintain a printer. Without changing the firmware and uploading it your self you can never be positive of what your running and if anything ever happens and you need to update or reload you won't know what to change.
