Description: Very light and powerful stepper motor suitable for use eg in 3D printers to drive the extruder. Weighs only 200g. Nema17
Product code: 276
The well-prepared extruder brings quality and precise printing, but also the possibility of using higher print speed of your 3D printer. Gear 3: 1 is adequate for everyday printing, but also for the printing system Volcano.
Lots of used extruders have problems with extrusion material when printing fine details or when printing narrow nozzle. The result may be a slight ripple on the printout. With the extruder to avoid this again due to large extrusion force and precise control of the retraction.
Because Titan uses a known gearing ratio and a consistently machined drive gear, we can offer a fairly accurate steps / mm set-point.
Steps per Unit (Extruder) = Motor Steps * Micro-stepping * Gear Ratio / (Hobb Diameter * Pi)
200 * 16 * 3 / (7.3 * 3.142) = 418.5 400 * 16 * 3 / (7.3 * 3.142) = 837
To test your value, mark the filament 120mm from the extruder then extrude 100mm slowly. If you do not measure 20mm after extrusion has finished, you may need to tweak this value.
