E-Steps per 1mm Filament on UM2?

Hey people,

I have a tiny question about the UM2. Does anyone know the actual value set for "E-Steps per 1mm Filament" on the UM2 ?

Showing "0" under "Machine Settings" in Cura, this means that the default value is used, this unknown value I would like to know.

I need this value probably for experimental adjustments of other extruder motors.

Can anyone explain me the calculation method otherwise ?

    Oh yes, thank you ...

    I have quite few messed up. I've always experimented only directly on the machine with the material flow. There, of course, I always had to readjust.

    Only in Cura, at the Machine settings, I have after the change in the GCode Flavor understood exactly what I must do.

    Once again, thank you :oops:

    Your motor has half as many steps per revolution as the stock one, so the correct steps per mm value is exactly half the normal value, assuming that you are using the normal drive knurled sleeve on the motor shaft.

    It's possible that the change steps-per-mm code doesn't correctly handle the transition to e coordinates being in cubic mm, not linear ones - I'd have to check the source later.

    Regarding the start gcode, you can make it do whatever you want. If you in comment and use the head/bed heater lines in the sample gcode, Cura won't add its own. Put those in whatever order you like.

    Oh yes, I have already seen the start and end codes in the RepRap Flavor in, I just do not dare to change anything. :oops: But I'll catch up immediately. :-P

    Then I'll put the E-Steps to 141 and continue to test, let's see if there are visible differences. :cool:

    Tests with the current value function ready. I have already printed successfully objects with a layer thickness of 0.06mm. And without professional testing, I can only say that the walls feel smoother. Irregularities in the material flow are not recognizable. :???:

    Thanks for the continued support.

    It has been found that a value somewhere 160-170 E-Steps provides the apparently best possible results.

     

    E Steps00E Steps01

    E Steps02E Steps03

    I think with this engine should be able to succeed, layers below 0.1mm, but that also needs to be intensively tested.
