Rostock MAX v2 Assembly Guide
First up, let's get the hot end resistors connected to the RAMBo. Bring the wires forward so
they exit the front opening of the printer and trim them so there is 6” of wire extending past the outside
edge of the machine. You'll be trimming the other “bare” wires to this length as well, but not yet.
Strip 1/4” off the black & red 18ga wires that come from the hot end. Insert them into the Heat
0 connector as shown below. Note that the black wire goes into the side with the “-” above it, and the
red wire goes into the side with the “+” above it. Tighten the screws for these two points on the
terminal block.
DO NOT, UNDER ANY CIRCUMSTANCES “TIN” THE LEADS GOING INTO
THE TERMINAL BLOCKS! DOING SO CAN CREATE AN INTERMITTENT OR HIGH-
RESISTANCE CONNECTION THAT COULD BECOME A FIRE HAZARD!
The next pair of wires to be installed are the
layer fan wires. These are the black & red, 26ga
wires that do
not have the knot tied in them. The
layer fan wires should be inserted into the terminal
block position marked “
Fan 0 ”. Strip 1/4” of
insulation off them and install them. You might
want to label this pair “
Layer Fan ” so that you can
readily tell them apart from the peek fan wires that
you'll install next.
Next up is – yep, the PEEK fan wires. This
is the pair of 26ga wires with the knot in them.
The PEEK fan wires are installed in the terminal
block at the location marked “
Heat 1 ”. You may
want to label this wire pair, “ PEEK Fan ” before
you install them.
A quick note about the PEEK fan wiring. The
firmware used on the RAMBo is configured to use a single hot end. Because of this, the Heat 1
terminal block position will automatically turn on the PEEK fan when the hot end is first heated and
