PrintrBot Plus LC
The Printrbot PLUS is the larger printrbot kit–containing an 8x8x8 build volume, laser cut birch construction, an assembled Ubis hot end, and 12mm Z-axis rods in an all-in-one kit. This kit also includes 1 lb of ABS filament.
This kit includes everything you need to build the printrbot PLUS:
- printrboard: all-in-one assembled electronics with integrated SD card slot (no soldering required)
- 5 NEMA 17 stepper motors complete with cable ends attached
- laser cut birch construction
- a few printed plastic parts (gears, etc)
- WOOD Extruder Kit
- hardware (8mm smooth rods, threaded rods, and bearings
- Z axis is 12mm smooth rods and 12 mm linear bearings )
- assembled Ubis hot end
- nuts, bolts, washers, zip ties
- laser cut print bed
- 8×8 heated bed
- misc assembled cables (no soldering required)
- 3 mechanical end stops (no soldering required)
- micro USB cable
nozzle
The Getting Started Guide says that all Printrbots currently ship with 0.4mm nozzles.
The convention for identifying nozzles is based on notches (or "rings") cut into the sides (vertices) of the hexagonal brass "nut".
No notch = 0.5mm
1 notch = 0.4mm
2 notches = 0.35mm

Most of information about it vanished from internet so here is some overview:

unlock chip using flip
It seems that chip is protected. However, trying to erase and program it did destry data in it (expect bootloader) for some reason, and it seem that dfu-programmer doesn't know how to work with protection features.
So, next step is to try atmel's flip under linux but this also doesn't work well.
