QR Ultimaker 2 Kit nog extruding enough

My QR Ultimaker 2 Kit with E-Steps set to 492.45 is underextruding.

If I calibrate the E-Steps myself, I need to enter 509.10 for the E-Steps to extrude enough filament.

Could it be that something is wrong with my steppermotor or gearbox?

Answer this question I have this problem too

Is this a good question?

Hi Harold, the esteps is verified and the gearbox has a fixed ratio of 5.18:1. What can affect is the setting of the thumbscrew adjuster, Normally to calibrate the extrusion the flow% is used and for best results each spool of filament needs to be calibrated, here is a link of how to do it in Simplify3D but the same procedure can be applie to Cura aswell.
