Rostock MAX v2 Assembly Guide
0 – Introduction and Acknowledgments
I’d like to welcome you to the second edition of the Rostock MAX v2 assembly guide!
Even if you've built an original Rostock MAX v1 3D 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 3D 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. 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. Note that the connector polarity is clearly marked on the board for
the “MOSFET Outputs”.
Making Crimped Connections
Towards the end of the build, you'll be required to apply four crimp on sockets to the extruder
wire extension. Teaching you how to properly crimp a connector is beyond the scope of this manual.
However, that being said, I've done a lot of research on this in order to make this task as easy and
accessible as I can. Chris Hansen over at Hansen Hobbies has written the most excellent treatise on the
use of inexpensive crimp tools that I've yet seen. You can download the PDF of the tutorial here:
http://www.hansenhobbies.com/products/connectors/Connectors.pdf
The focus on the tutorial is on connectors commonly found on R/C servos, but the crimp
sockets featured are essentially identical to those that you'll be required to use during your Rostock
MAX v2 Build.

Acknowledgments
I'd like to thank the gentleman that runs http://minow.blogspot.com.au/ for his excellent guide
on calibrating delta configuration 3D 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.

Rostock MAX v2 Assembly Guide
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.
•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
•5/16” open-ended wrench (Used primarily on the nuts that hold the Cheapskates together)
•2 7/16” open end wrenches. (used to adjust Cheapskate Bearings)
•11/16” open-ended wrench (used for hot-end mount)
8

Rostock MAX v2 Assembly Guide
•PermaTex Ultra Copper High Temp RT
•A small razor knife like an X-Acto knife. This will be handy for cleaning the flashing off the
injection molded parts.
•1/2” wide roll of Kapton tape
•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.
•Blue thread locking compound (Loctite or Permatex Threadlocker Blue)
•A small file.
•Elmer's Glue Stick – must be marked “Disappearing Purple”.
•Toothpicks
•Isopropyl Alcohol
•12” framing square.
•1 Roll of ABS filament. Needed to print the fan shrouds at the end of the build.

Rostock MAX v2 Assembly Guide
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:

Rostock MAX v2 Assembly Guide
2 – isual Bill of Materials
The Rostock MAX v2 kit shipping box should contain the following items:
•Four Melamine laser cut part sheets
•1 Acrylic Parts Package
•1 Power Supply
•1 Hardware Box
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.
11
Fig. 1-1: Shipping box contents.

Rostock MAX v2 Assembly Guide
The Melamine parts are covered with a special cutting mask that prevents the laser cutting
operation from depositing cutting byproducts on the Melamine surface. You'll need to remove all of
this material before beginning construction.
This process is called the Five Stages of Masking Tape.
1. Denial - Oh there's no way I need to scrape all this tape off those parts? Do I?
2. Anger - @#$%@#! This sucks! I've NE ER SEEN SO MUCH TAPE IN
ONE PLACE IN MY LIFE!
3. Bargaining - “Well hi there, Significant Other! Would you PLEASE remove
all this tape for me? PLEASE?”
4. Depression - This tape hates me. *sobs quietly*
5. Acceptance - Well I suppose if I'm ever going to get this thing built, I'd better
get on with it and get all this tape removed...*sigh*
Ok, it's not THAT bad, it just seems like it. It beats having sticky residue all over your nice and
clean Melamine parts. :)
You'll notice that there's a few strips of 2” wide masking to remove as well. This tape holds the
parts in the sheets so they're not damaged during shipping. I recommend removing this tape FIRST.
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.
12

Rostock MAX v2 Assembly Guide
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 Depot 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!
