Software
- Download free from https://ultimaker.com/software/ultimaker-cura

- Find (or create) models to print: e.g. https://www.thingiverse.com (many other sites)
- Convert (aka Slicing) model file (.STL) into GCode file
- Load GCode into SDCard
- Turn on printer (hotend should start to heat up) see touch-screen menu beside power-button, wait till ~200 celsius or whatever you configured in your Cura profile.
- Load filament (skip if already loaded)
- Use touch menu → Print → choose Gcode File → Print
- Printer will start cranking when temperatures (nozzle & heatbed) hit configured targets
Tuning
Areas | Descriptions |
Retraction | Reduce stringy prints but too much retraction can cause jams. https://all3dp.com/2/3d-printer-retraction-speed-what-does-it-mean/ |
Bed temperature | Plastics like ABS may lift off from print bed due to warping without a heated bed. Check vendor specs & Cura profile. |
Troubleshoot
Symptoms | Descriptions |
Jamming | Start to hear clicking or grinding sounds in the middle of prints.

Spool not rolling | Sometimes while removing filament from printer, the spool coil starts to enlarge, once you lose your grip over filament, it gets tangled or cris-crossed into a coil. Will end up partial model & printer will just happily go on without filament extruded.
Use a clip to hold the filament in place after removing from printer. |
