31 Tips
Before even attempting the first print it is vital that the printer is correctly calibrated.
Skipping or rushing this step will result in frustration and failed prints later, so it is
important to take the time to make sure the machine is correctly set up.
Each machine may have its own calibration procedure and this manual will not
attempt to cover all the variations. Instead here is a list of key points that should be
addressed.
Frame is stable and correctly aligned.
Rods are correctly aligned
Belts are taut.
Driving wheel turns smoothly
Bed is level in relation to the path of the extruder.
Filament rolls freely from the spool, without causing too much tension on the
extruder.
Current for stepper motors is set to the correct level.
Wires are correctly connected
Couplings and pulleys are fixed tightly
Firmware settings are correct including: axis movement speeds and acceleration;
temperature control; end-stops; motor directions.
Extruder is calibrated in the firmware with the correct steps per mm of filament.
The point regarding the extruder step rate is vital. Slic3r expects that the machine will
accurately produce a set amount of filament when told to do so. Too much will result
in blobs and other imperfections in the print, too little will result in gaps and poor
inter-layer adhesion. For how to set up the printer, please check the user manual
