E steps /mm

Hi i was wondering what Esteps/mm settings you guys have.
My default setting was 200 but after calibrating i came to a value of 300 !!!

I gave a manual command to extrude 100mm filament but only 67mm came out with the default settings.

I am down to approx 147 (I have no access to the printer)

Thats a huge difference for the same machine !! I hope more people will post their values here so we can see the difference.

I have set the value to 148,6.
My two extruders are slightly different, and 148,6 is the middle of the two. In cura I print with 99% flow on one extruder, and 101% on the other. But I only print “single mode”.

I’m wondering if we are talking about the same printer.

For my K8400 I need a E scaling of 153 steps/mm.

@basvaningen; that’s weird. Only viable reason would be;

-1/64 microstep (not possible with the used stepperdriver)
-using a 400 steps/360 degree stepper for the extruder
-using a smaller diameter drive-pulley.

either way, i’m in the 152.something steps per mm iirc, more ore less what others use. Took an average of 3 pretty accurate measurements.

I use 140 steps/mm. extruding at 1,2,3 mm/s with the original setting of 200 steps/mm gave almost identical results that was 157steps/mm. These tests where done with ABS. Practical tests have showed that 140 steps/mm gives better results with Slic3r. The load settings for filament has to be changed as well since a new setting of the steps/mm will not advance the filament enough to get it out of the extruder.

I am using version 1.4 for dual heads and unfortunately there is no way to move the second extruder, only the first. Is this correct?

Best Regards

I use 148,7 steps/mm with Cinyas feeder 1.1 as a mod based on PLA. Have been considering redoing the calibration test sins i replaced the filament spool holder for a “frictionless” solution so the filament spool dont hold as much uneven weight load on the feeder. But i dont think it will change dramaticly but probably a litle considering the pull load.

Frictionless spoolholder? That’s intriguing, got a link Mr. Marlark?

Kind regards

I shouldnt say it is frictionless but more like the designer say it Low friction. thingiverse.com/thing:1067052

Reason why it is useful is that when the spools is on the original spool holder the feeder pull the load of the spool based on the weight and the size of the center hole of the spool. With this holder the feeder dont need to pull the same load to push the filament forward. it have enouph issues pushing the filament thru a 0,35mm hole so to say it dont need to add the force needed to turn the filament spool when dragging the filament into the feeder. Basecly it just makes the life of being a filament feeder simpler :wink: Funny thing is when unloading the filament it actualy is so frictionless that it can turn the filament spool backward. The original just turns the filament out in free air so you have to wind the filament back to the spool.
