Calibration
Posted: Thu Jul 31, 2014 1:12 pm
Are there any generalized, straight-forward discussions of calibrating a 3D printer?
It seems to me that there are a couple of things which one has to calibrate for, and some are at a machine level, others are specific to a given roll / lot / colour of filament, while others are software tweaks to a slicing program which may be further adjusted for a given project.
First there's the mechanical setup:
- extruder motor steps --- this has to be adjusted to match the exact diameter of the hobbed bolt and how well the filament moves through the machine --- may require different values for types of filament, e.g. PLA vs. ABS (presumably 'cause of differing stiffnesses of the plastic and how slippery it is and how it reacts to being grabbed by the hobbed bolt).
Then there's calibration for a given lot / colour of filament:
- measure the filament to get the average diameter
- test print the filament to determine the optimal temperature(s)
Then one would need to configure slicer parameters.
