massive overextrusion, E-Steps are calibrated
-
Yes, looks right. G92 Z0 and then G1 Z100 is moving 100mm on Z-Axis. Just double-checked.
-
how sure are you that you have a 0.4mm nozzle?
-
I replaced my old nozzle 2 days ago (Where i also had the same problems ) with a completely new 0.4 Microswiss nozzle. Which should be ok.
-
measure the weight of 100mm filament
then extrude 100mm filament through the hotend and weight that.
if its the same, the problem must be in the slicer.
-
Veti, thx for the hint! Dont have that precise scales here atm. Will do it these days. But...my guess is, that there are some Issues with my config / Firmware. I have 3 different printers (not running with duet Wifi) where i dont have these issues. As mentioned i tried 3 different slicers (Cura, superslicer, simplify3d). The phenomen with the overextrusion is there, regardless which slicer i am using. Which makes me wonder that it is not only a few percentage... its like 50%
Also using Highquality filaments ( Filamentum, Extrudr, etc) so there shouldnt be that variance.

@deckingman thx for taking part in the discussion. I saw an old thread from you where there was quite a similar problem which suddenly disappeared. I love your great multicolor Printer !

Thanks. But due to various firmware issues, it's currently just a useless pile of extrusion and motors.

Can you post your config.g?
Can you post your homeall.g?
Can you post the entire gcode file or at least the first 50 or so lines of it?
Can you send M122 and post the results?
Can you send M98 P"config.g" and post the results?Is this just the first layer that is over extruded or are you letting the print progress to higher layers to allow for any incorrect Z0 position to be overcome?
Might be worth going through this complete calibration? https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40

No, not set to volumetric

@Enpixa said in massive overextrusion, E-Steps are calibrated:
M906 X1300 Y1300 Z1200 E1200 I50 ; set motor currents (mA) and motor idle factor in per cent
which motor is on your bondtech?

Veti, it is the original Wanhao motor. But it is not getting hot when printing. it seems ok.

Here are some Photos with 100% flow. Retraction: tried everything between 2-8mm, makes a difference, but doesnt avoid overextrusion.
and some settings screenshot:
as mentioned before the "Marlin-Style" Favor was only a test, made no difference compared to "reprap-style"

Hi,
Is the slicer set to use absolute or relative extrusion mode?
Frederick
Printers: a small Utilmaker style, a small CoreXY and a E3D MS/TC setup. Various hotends. Using Duet 3 hardware running 3.4.6

at the moment it is set to absolute in slicer. also M82 in config.g.
Also tried it with relative in slicer and M83 in config... same overextrusion. as mentioned before, also tried 3 different slicers (Cura, Supersclicer, Simpflify3D) -
Hi,
Well I've always been told to use relative but if you tried it already then it must be something else.
The only two things that come to mind are the settings in M92 or perhaps a the presence of a "rogue" M122 command.
I'll keep thinking.

@Enpixa You need to adjust that first layer. The nozzle is too near the build platform. You can see it in the fact that it's leaving a line in the non-print moves between those circular features are the rest is just too squashed. So it looks like over extrusion because it's being forced out sideways due to the proximity of the nozzle to the build plate. Use baby stepping if necessary but whatever means you use, the nozzle needs to be 0.2mm or so higher on that first layer.

Deckingman, you are right, that was due the testing-phase, will increase the distance and show you updates soon. Had tested everything from very close (now) to very far ) Didnt help with the overextrusion.
