Changes

* '''Support fails:''' If the support gets really stringy as the print continues and in turn fails the print, see if you can have a supervisor help you change the density of the support. Double check that the printer is not shaking too much as you print your model. If you still don't know what to do after your print fails, ask a supervisor.

* '''First layer of print warps:''' If the first layer of your print warps and affects the rest of your print, lower the bed temperature, and start the print again. If it continues to warp, try adding some adhesive on the printer bed.

* '''Thermal Runaway:''' Thermal Runaway is a safety feature designed to prevent the printer from accidentally catching fire. If your printer's thermistor would somehow dislodge itself, electronic parts would get a lower (incorrect) temperature reading. In an attempt to compensate for the lower temperature, the heater would reach dangerously high temperatures, with the printer potentially becoming a fire hazard. Thermal Runaway prevents that from happening. Thermal Runaway is configured to shut down the printer when the temperature drops by more than 15°C for more than 45 seconds. If the temperature reading doesn't recover in the set time period, the printer will shut down and display the Thermal Runaway error. All hotend heaters are thoroughly tested, so they can run at 200°C with the print cooling fan at a 100% speed. To print materials that require higher temperatures, the speed of the fan must be decreased.

All hotend heaters are thoroughly tested, so they can run at 200°C with the print cooling fan at a 100% speed. To print materials that require higher temperatures (like PLA at 215°C), the speed of the fan must be decreased in the Prusa Slicer software or manually during the print. Incorrect fan speeds are sometimes the result of using gcode from a different type of printer. Pay attention to your prints as they start the second layer, as this is usually when the print cooling fan kicks in.
