Describe your issue: New to 3D printing. Thins is my first print after installing Klipper. I think I’m having layer shift issues
…
That doesn’t look to me like what’s typically referred to as layer shifts. If you pick one of the layers where the corner seems to be protruding a bit and follow it back to the adjacent corner, that corner is not offset inward by a similar amount. If it were, that might indicate a layer shift problem.
The inconsistent corners could be a result of a number of things. The first ones that come to mind:
- Inconsistent filament width
- Over-extruding
- Printing too fast
- Incorrectly calibrated (or not calibrated) pressure advance
If it were me, I’d try these things in this order:
- Take multiple measurements of the filament with calipers to make sure you’re within +/- 0.3 mm or so of the median thickness. (If it’s significantly more than that, you may just have to live with inconsistent extrusion while using this filament, or go down the filament width sensor rabbit hole.)
- Dial in the correct extrusion multiplier for this filament to make sure the printer is extruding exactly the amount of filament that the slicer assumes it is.
- Run the pressure advance calibration procedure.
- Print at a moderate speed. (That varies, but for my Ender 3, I’d use 60 mm/s.)
If that fixes the corners issue, then you can experiment with increasing the print speed until you consider the quality degradation unacceptable.
Also, looking at the pictures again at 100% scale (especially the second picture), there appear to be tiny surface artifacts on each of the extruded lines. That could be an indicator that your filament isn’t dry enough. “Wet” filament could also contribute to the inconsistent extrusion you’re seeing here.
Can we see the klippy.log?
Thank you, I will try it get back to you. I’ll dry the filament as well
I will upload it as soon as I get home. Thank you

Here it is. Sorry about the wait
It appears that the steppers you use run in standalone mode.
You may check the current of the steppers:
Or take care for s proper cooling.
Steppers can lose tiny steps when they get too hot.
Don’t think it is due to lost steps.
But in standalone mode the chance is high the vRef is wrong.
The frazzled edge on the left could be from the Z seam and bad retraction settings.
The wider bottom is due to overextrusion and/or nozzle too close to the bed and that gradually becomes better but layer cooling is causing shrinking until everything is settled.
Changing filament cross section can induce imperfections in the layers as well!
The printer at least needs to be tuned more.
Turns out my extruder arm was broken. Now I adjusted the e steps and is printing a little better. I will do the pressure advance tuning next since I haven’t tried it

It doesn’t look like layer shift. It looks like the bed level or first layer is off. If you are using the stock removable magnetic bed then I would suspect that. If you can use a glass surface to print on, that will help. Also the lead screw may not be seated fully into the coupler that couples the lead screw to the stepper motor.
