Prusa i3 MK2S .204 Area: CNC


A very nice for 2018 filament-based (FDM) 3D printer. There are currently three of these at PS1, the other two being .202 and .203.

Uses 1.75 mm filament. Capable of printing many different kinds of filament. Ships with 0.4 mm nozzles.

See for details.




1. Prepare the Printer

1a. Clean the nozzle

1b. Check/Load material spool

Remove existing spool, if necessary.

1c. Clean the bed

1d. Set printer settings for your job

put info here - note: for the 203 OctoPrint printer, you can control & monitor bed & nozzle temps

2. Prepare Your .STL file

3. Upload & Print Your .STL File

3(a). The Prusa i3 MK2S printers at IP address and

These two printers do not use OctoPrint. You must load your STL files directly onto the printer using SD Cards (some are provided at PS1).

3(a)1. Load your .STL file onto an SD card (some are provided at PS1).

3(a)2. Insert SD card into printer.

3(a)3. Then...[put info here]

3(b). The Prusa i3 MK2S printer at IP address (OctoPrint)

This printer uses the Prusa i3 OctoPrint Server to manage the print job queue. Note the SD Card reader in this printer may not work [confirm].

3(b)1. Open a web browser connected to a computer/device on the PS1 network & enter in the IP address field.

Note: If printer has been turned off, you may need to first select "Connect" under the left side Connection tab if the printer has been turned off. All settings to connect are retained and should not be modified.

3(b)2. Warm up the printer (if you haven't already) using the controls on the Temperature tab -- enter a temperature in Celsius and click "Set"

3(b)3. Set printer's feed & flow rates, as well as fan settings (if you haven't already done so on the printer). You can control the printer' movements & extrusion in the 'Control' tab.

3(b)4. Upload STL file using the left side "Files" tab.

3(b)5. Find the STL you uploaded and click the "Slice" button (it looks like a magic wand). Note: Cura is the default slicing engine.

3(b)6. Select one of the preset slicing profiles, and then manually set your preferred temperatures and speeds using the Basic and Advanced tabs. This will generate G-Code, exporting a GCO file.

3(b)7. Locate your GCO (G-Code) file in the Files tab on the left side. Click 'Load and Print' to print your object.

This is only a high level overview of how to use OctoPrint. If you are already authorized but have not used OctoPrint, feel free to attend future authorization sessions. OctoPrint will accept g-code from the most popular slicers such as Cura, Slic3r, Repetier-Host, and Simplify3D.

4. Post-Printing

After your printing is complete, follow these guidelines.

4a. Delete your files

Delete your files from the OctoPrint server and/or borrowed SD cards. You can download your GCO file for future printing if you would like to retain the specific sliced project.
