Rostock MAX v2 Assembly Guide – 4thEd.
0 – Introduction and Acknowledgments
I’d like to welcome you to the 4th Edition of the Rostock MAX v2 assembly guide!
Even if you've built an original Rostock MAX v1 3 printer, you'll want to read this manual
carefully. There are no common Melamine parts from the v1 design. The construction has been greatly
streamlined and should prove to be a shorter build. The design changes made will ensure that you've
got a long lasting, easy to calibrate, delta configuration 3 printer.
Please read this entire guide before you begin assembly of your new Rostock MAX v2! It will
help you avoid any unpleasant surprises and will ensure that you’ve got everything you need BEFORE
you need it! Understand that the photographs in this assembly guide do NOT tell the whole story of
each step! Make sure you read and understand the accompanying text for each step!
A quick note on the RAMBo, the controller for your Rostock MAX v2. The RAMBo is static
sensitive, so please don't take it out of the static bag it ships in until you're ready to use it.
The box containing the RAMBo and its wiring should also contain a printed, black & white
sheet that looks like this:
http://www.reprap.org/wiki/File:Rambo-conn-all.jpg
Please refer to this sheet when you reach Chapter 18. This is a valuable guide to wiring the
RAMBo up to your Rostock MAX v2. Note that the connector polarity is clearly marked on the board
for the “MOSFET Outputs”.
The Five Stages of Masking Tape...have been removed!
In a change from previous editions of the Rostock MAX v2 assembly guide, I'm going to spare
you the time consuming task of removing all the parts from the laser cut sheets at one time. For the 4th
Edition, you'll only “pull & peel” the parts as you need them. In order to help you locate the required
parts, each task section will show the part, what sheet it comes on, and how many of them you need.
This will also help avoid lost parts or parts that get thrown out accidentally.
Acknowledgments
I'd like to thank the gentleman that runs http://minow.blogspot.com.au/ for his excellent guide
on calibrating delta configuration 3 printers.
I'd also like to thank the whole gang over at the SeeMeCNC forums for providing excellent
feedback. This would be a much lesser creation without their contributions and insights.

1 – Required Tools And Materials
Before you begin assembly of your Rostock MAX v2, please make sure you’ve got everything
on the following list of tools and additional materials.
Tools
•P1 & P2 sized Phillips screwdrivers
•Standard flat head screwdriver
•A small flat head screwdriver.
•3/32” Allen (hex) wrench. A ball-end, T-handle version is a good choice for this and the other
sizes of Allen wrenches used
•5/32” Allen (hex) wrench.
•7/64” Allen (hex) wrench.
•Needle nose pliers
•Slip joint pliers
•Forceps – these will come in handy when routing the belts and reaching for small, hard to reach
parts. They can be purchased from Amazon for as little as $3.50 for a set of two.
•Wire strippers
•Wire cutters (flush cut type)
•Wire crimping tool, similar to the one below. Used for crimping power supply wiring.
1 – Required Tools And Materials – 6

Rostock MAX v2 Assembly Guide – 4thEd.
•5/16” open-ended wrench.
•11/16” open-ended wrench (used for hot-end mount)
•A digital caliper. These can be purchased from Harbor Freight tools for around $10.
•A small squeeze clamp that can open at least 6”
•Battery powered screwdriver. If you ever needed an excuse to buy one of these, THIS IS IT.
•Pencil.
•40W Soldering Iron.
•Solder. (Example: https://www.sparkfun.com/products/9161)
•Blue thread locking compound (Loctite or Permatex Threadlocker Blue)
•A small file.
•12” framing square.
•A small razor knife like an X-Acto knife. This will be handy for cleaning the flashing off the
injection molded parts.
Additional Materials
•Toothpicks
•Isopropyl Alcohol
•1 Roll of ABS filament. Needed to print the fan shrouds at the end of the build.
•PermaTex Ultra Copper High Temp RTV
•1/2” wide roll of Kapton tape ($7-$10 at Amazon, search for “Kapton 1/2”.
•Elmer's Glue Stick – must be marked “ isappearing Purple”.
1 – Required Tools And Materials – 7

Rostock MAX v2 Assembly Guide – 4thEd.
The following is a list of optional things that can make your life easier in the long run.
•Electrician's tape.
•Standard sized nylon wire ties.
•Waxed lacing cord. You can use this in place of wire ties in pretty much any application. You
can find it here: http://www.skygeek.com/wht-string.html. While expensive, you'll never really
need to buy a wire tie again and it'll likely last you the rest of your life. :)
I'd also recommend a little plastic box with part compartments in it. They're really cheap at
craft stores and are perfect for building a kit like this – you can store all the various fasteners and have
them ready to go as you need them. Here's the one I use for my various projects:
1 – Required Tools And Materials – 8

Rostock MAX v2 Assembly Guide – 4thEd.
2 – isual Bill of Materials
The Rostock MAX v2 kit shipping box should contain the following items:
•Four Melamine laser cut part sheets. (3 full, 1 partial) [84301]
•1 Smoked Acrylic Parts Package [84302]
•1 310mm x 3mm Borosilicate Glass Build Plate [26602]
•3 T-Slot Rail, 1” (25mm) square x 32” (812mm) long aluminum [68310]
•1 Power Supply 12V C, 30A Model LIHUA-360W [26733]
•1 Rostock MAX v2 Electronics and Hardware Pack, Rev3.
If you're planning on painting your Rostock MAX v2, especially the part edges, you would be
well served to carefully trace the outline of each part with a razor knife in order to cut the supporting
masking tape. This way you can retain the protective mask on the parts in order to make painting the
edges easier. Otherwise you'll have to re-apply a mask to avoid getting paint on the Melamine surfaces
of the parts.
2 – Visual Bill of Materials – 9
Shipping box contents.

Rostock MAX v2 Assembly Guide – 4thEd.
The Melamine parts are covered with a special cutting mask that prevents the laser cutting
operation from depositing cutting byproducts on the Melamine surface.
Leave this protective covering on the parts until you need them. This will save you the
laborious task of stripping all the masking tape off before the build. Note that if you want to paint your
Rostock MAX v2, you'll probably want to go ahead and strip the masking off of the parts now. If you
do so, please keep the parts grouped by sheet. When I specify parts for a task, I'll let you know what
sheet you can find them. If you don't keep them grouped together by sheet number after you paint
them, you'll spend more time looking for the parts I call out for a particular step.
Take special care when removing the laser cut parts from the sheets. Sometimes the laser
doesn't quite cut all the way through. If you find a part like this, you'll want to gently score the back
side of the sheet along the faint cut line and then press the part out from the front of the sheet. The
front and back of the sheet is easily identifiable – the front of the sheet will have very dark laser cut
lines with “flash” deposits to either side of the laser cut line. The back of the sheet will have much
fainter marks.
Note, the part sheets shown above will differ slightly from those that you have in your kit.

The white cardboard box will contain the laser cut Acrylic parts that are used in the build.
The Acrylic parts have a paper protective covering on them. Please leave that in place until
you're ready to install them.
The large cardboard box contains the hardware & electronic components required to build the
Rostock MAX v2. Many are in individual baggies, some are in heat-sealed bag “packs”. As you go
through the following Bill of Materials, please count and check off each item. This is important as you
don't want to be short a vital part during the build. It's better to find out before hand than being forced
to stop the assembly process due to a missing part. If you are missing any parts, please contact
[email protected] with the subject line of “Missing Parts!”.

For those that aren't sure how to identify the various screw types, Bolt epot has made
available some excellent references. I would recommend Fastener Basics
(http://www.boltdepot.com/fastener-information/Printable-Tools/Fastener-Basics.pdf) and their
Fastener Type Chart (http://www.boltdepot.com/fastener-information/Type-Chart.aspx).
Let's go ahead and do an inventory of the parts to ensure that you're not missing anything!
Please check off each item as you locate it. Where possible, I'll include the SeeMeCNC part number
