    Over extrusion despite E-step calibration with micro swiss direct drive extruder

    Hello Everyone,

    i am in the process of commissioning a micro swiss direct drive extruder. I calibrated the e-steps and verified the value multiple times with and without PTFE tubes/hotend attached. When printing a singe walled box i get a Wall thickness of 0.46 mm corresponding to a flow correction value of 0.87.

    That seems excessive. Also the e-steps of 140 seem very high to me (before it was 96). Any idea what could be wrong or are values like that somehow normal for direct drive?

    .87 flow rate is pretty much my normal with a .4mm nozzle on my direct drive printers (custom built BLV CoreXY printers). With a .5 nozzle I'm around .91 flow rate and higher with a .6 nozzle.

    OK, thanks for the input
