Introducing the MPSCARA!
WARNING: This project is still a work in progress, we cannot promise that it will run as well as intended, but are committed to helping everyone get their machines operating as smoothly as possible. It still requires a lot of polish, but we will be continuing with our updates as we produce them. Thank you for your patience, please comment or message with any issues you run into while building/using your MPSCARA and we will do our best to help!
This is a SCARA robotic arm designed to be a cheap, compact, and easy-to-build 3D printer. It can also be equipped with a marker (An older version of the MPSCARA using the marker can be found here), with further tools potentially on the way. It is heavily based off Idegraaf's design, with some quality-of-life updates added in.
If you are interested in building one yourself, download the V1_MPSCARA.zip file and crack it open. It contains...
- V1.X Marlin - Preconfigured marlin firmware for your MPSCARA V1
- V1.X Software - A Python-based gcode conversion script, complete with usage instructions and comments.
- V1.X STL Files - A full repository of STL files needed to build your very own MPSCARA V1
- Bill of Materials V1.X - In excel and pdf formats, complete with prices and links to where the components may be purchased. Note: Most hardware will be available at nearby hardware stores, and likely sold in lower bulk than online, I strongly suggest you check those locations first to get better deals.
- MPSCARA Instructions V1.X - Also known as a process plan or construction instructions, this tells you exactly how to build, wire up, and install the firmware onto your MPSCARA.
As the file names imply, this is the first iteration of all these distinct components. If any issues are encountered, or any clarifying questions arise, the files will be updated along with notes on this page to indicate what was changed and why (Along with version increments on the related files). That being said, please comment on here or PM me with questions or suggestions for this project.
Special thanks to Professor Mark Ganter for guidance, Ashley Pigott for testing and proof-reading, and Molly Carton for advice.
The MPSCARA was designed, built, and tested in the Solheim Additive Manufacturing Lab at the University of Washington.
Used 3 perimeters and 4 layers top and bottom. None of the printed parts seemed particularly flimsy using those settings. Used PLA filament.
How to Get the BEST out of your MPSCARA Construction Experience
Depending on your printer, some pieces may be printed with slight lips at the bottoms. In order to save frustration, it is suggested that those are gently filed off, especially on the following pieces:
Otherwise, be sure to carefully follow the process plan included in the zip file. Most of the machine is fairly straight-forward, but there are some little tricks in there that help quite a bit.
Released on 10/2/2017
-Accidentally uploaded wrong Linear Bearing file, V1.1 now has the notch mentioned in the instructions. If you already printed the V1 of this part 3 times, you only need to print one of the V1.1s for use on the bearing that connects to the Endstop Clip. The notch helps keep the clip from rotating
-Increased height of the Baseplate file in order to increase stability of the 8mm rods.
-Added more comments to the software to give more detailed error messages.
Quality of Life
-Uploading the major components separately as well as in the combined ZIP file. (Software, STLs, and Marlin are in their own files so you don't need to download the entire new file if you only need to do partial updates.)
-Uploaded wrong file for Z Carriage Bottom, new file specifies that the 'Y' wires are on that piece. No structural/functional changes, simply changed for ease of wiring/assembly.
