Moving forward, all g-code files for printing at Seattle Makers will be created using PrusaSlicer.

PrusaSlicer is a free, powerful slicer that can also be extremely easy to use for all skill levels. This means you can experiment slicing at home before sending in your STL file, and get an idea of materials/time usage. Anyone can download it and with basic training, get a reasonable estimate on time to print.

Quick Print

  1. Import into PrusaSlicer
  2. Select settings
  3. Export G-Code
    • If using a Seattle Makers Computer, you can directly export to OctoPrint. If you check “Start print after upload,” Your print will start!
    • If not, export to desktop (or anywhere on your machine, just remember it) and move on to the next step.
  4. Open a web browser while on Seattle Makers Wifi and go to octopi{printername}.local example: octopifranklin.local

  • Clean/Prepare the bed

3. Send G-Code To Printer (Start Printer)

No longer will you have to transfer your files to an SD card, and then manually insert the card into the printer. Using a raspberry pi and a program called OctoPrint, we now can send our G-Code directly from the slicer or web interface to the printer.

If you are having trouble with an Octoprint Interface, please ask a Maketeer. SD cards can be used as a backup, but please defer to them to make that determination.
