See how others built their Generation 7 Electronics board and where they used it. Gen7 is pretty universal, you can control anything from a printer to a milling machine.

Markus "Traumflug" Hitter showing Gen7 replication

One of the main development goals of Generation 7 Electronics is to make RepRap electronics replicatable, just like mechanics. This doesn't include printing resistors or integrated circuits, yet, but I think a first step is done already.

Thanks a lot to Mateusz for editing this video.

peter6960's ( use of Gen7 Boards (March 2012 - May 2013)

I have always loved the Gen 7 - bulletproof, simple, reliable. Easy to make, Easy to fix. Why you would want to use any other advanced controller baffels me

March 2012 - My first Gen 7 1.4.1 on a DIY Printrbot
August 2012 - built my second Printrbot - Still using Gen 7 1.4.1 on both
August 2012 - Gen 7 1.4.1
Reliably running a bowden setup for a while on a Gen 7 1.4.1 on PB no 3
Another Gen 7 1.4.1 I helped a buddy in Mpumalanga assemble
Got Repetier Firmware with I2C LCD running after a long battle

Built a 1.5 for my EcksbotZA in Dec 2012
Etched one of Xoan's reworked Gen 7 1.5S boards
Loved it so much I made up one panel to use for my botfarm - March 2013
Neatly mounted on one of my EcksbotZAs - May 2013
Rack of Ecksbots all running Gen 7 1.5s
another Ecksbot with Gen 7 1.5 at the office

All-in-all I think I've personally had about 12 Gen 7's over the years, with probably another 20 made for friends, collegues and at the local hackerspace

This is Holger J.'s Prusa i2 driven by a Gen7 v1.5. Nice work, Holger!

I have soldered a Gen7 v1.3 board. It's working with the Teacup firmware. The PCB and components were supplied by Traumflug.

This video, also shown on the page, clearly shows a Printrbot driven by a Gen7 v1.2. Nice!

It was my first attempt on milling a PCB on my Solsylva 10x9 using Eagle and pcb-gcode. Not the prettiest, but it's been working great.


Etched a couple V1.1 boards a while ago. I have one on my prusa and one for my test_tube_mendel when I get it that far. The prusa is jogging around but no prints yet as I haven't got the extruder going. Now I have a few more in process for the Vertical_X_Axis_Standard_Contest. They are V1.3 boards.
