13.7 Printing problems
13.7.1 Layers break and split when printing from ABS material
ABS material has a higher thermal expansion than other materials. We suggest other
materials like PET, HIPS or PLA when you print larger models.
13.7.2 Models contain either too much or not enough of the filament
You can manage the filament flow during the print. Use the LCD-knob and choose
LCD
Menu - Tune - Flow - xx%
where you can adjust the filament flow. Pronterface users can
enter the value M221 Sxx into the command line.
When you change the filament flow, the next print will use the same settings unless
you change it again in the menu, or reset the printer, or unplug it from the power
source.
13.8 Problems with finished models
13.8.1 Model breaks and/or is easily damaged
This is a typical feature of larger models printed from ABS. If you have set the temperature
properly, the printer is away from drafts and object design is right, the printed object should
not break. The easiest way to avoid breaking, or overall model fragility, is to choose a
different material. The strongest are PET, HIPS and PLA; while PLA has low heat resistance,
PET is the firmest and has the lowest thermal expansion.
When parts break and there is no spare time to reprint the model you can use
super glue or any other glue for plastics for temporary fix :).
