Type A Series 1
The Type A Series 1 has the largest capacity of any printer in our fleet.
Tool Steward: Matt Keveney (@mkeveney on Slack).
Primary documentation for all our 3D printers is the course materal for our 3D printing 101 class. It has a section specific to our Type-A, and is a must-read before using this printer. Note: In 2016 and 2017 we heavily modified this printer, making much of the earlier documentation obsolete. For historic interest, you may find a PDF of the original manual here.
We have added a printer profile and a PLA profile (for unheated beds) to the Prusa-edition Slic3r program installed on the 3D print computer. If you'd like to install these profiles on your own computer:
Download and Install the Prusa Slic3r if you haven't already.
- Find the right directory for your installation:
- Windows: "C:\Users\Public\Documents\Prusa3D\Slic3r settings MK2"
- Mac: "~/Library/Application Support/Slic3rPE/"
- Unix / Linux: "~/.Slic3r/" (UNVERIFIED)
- There should be three subdirectories called filament, print, and
- Download and unpack this zip file.
- Put the AMT Type A.ini file in the printer directory
Any slicer that puts out standard 'reprap-style' g-code may be used with the Type A. The following specs will help you configure it.
- Print volume x: 260, y: 230, z: 200
- Nozzle 0.40mm (we replaced the original 0.5mm nozzle in 2016)
- GCode flavor: RepRap/Marlin
- Auto leveling: add a G28 and a G29 command to the initialization sequence. See the Prusa Slic3r files for an example.
The firmware is a fork of Marln, maintained here:
Beware the wonky wire bundle!
The wires leading to the printhead have a devious tendency to twist in such a way that they interfere with the carriage X homing function. If the printer makes a horrible grinding noise when homing, this is probably it. We should really fix this, but meanwhile, just be careful to twist the wire out of the way before starting a print:
