STACKER 500KS USER GUIDE 37
7. Volumetric Calibration
The secret to accurate prints and beautiful surface finish is proper volumetric flow control. We
control volume with four variables: (1) filament diameter, (2) nozzle size, (3) filament drive
ESTEPS, and (4) extrusion multiplier. The slicing engines use these variables to determine exactly
how much filament to extrude. Therefore, it’s essential to set these variables carefully and
accurately.
(1)
Filament Diameter:
It’s very important to only use filament with highly consistent filament
diameters. That is why STACKER has partnered with ColorFabb to manufacture our filaments.
ColorFabb uses highly advanced laser tools for precise diametric measurements, as well as a host
of other controls to ensure consistent filament diameters. Regardless of what filament brand you
use, start with a digital caliper and measure the diameter of your filament in few different places to
see if it is consistent. If the diameter is inconsistent, return the filament to where you purchased it.
Once you have established the consistency of your filament diameter, be sure to insert the
measured value into your slicer settings.
1. Click on the Slicer Tab
2. Click on the Configuration to open the Slicer window
3. Select the Filament Settings tab
4. Enter your Filament Diameter
(2) Nozzle Size:
STACKER nozzles use a system of small machined dots around the tip for
identification purposes. You need to make sure you are entering the proper nozzle size in your
slicing engine, as well as, the printer configuration in STACKER RUN. STACKER’s standard nozzle
size is 0.5mm, also called a 050 nozzle.
