Elephantfoot and layer shift  

Re: Elephantfoot and layer shift

Here are some macros:

Re: Elephantfoot and layer shift

what you show us here is not a layer shift. layer shifting is a remaining shift like at this object (from another thread):

your imperfect layer matching is caused by the repetition clearance of the printbed and the extruder.
as you already mentioned: the belt tension plays a role here. but more bearing clearance (or binding in case of drylin bearings) and maybe pulley clearance as well. even the way the bearings are fixed influences this behaviour.

the "elephant foot" effect is probably caused by the temperature gradient that you get when the printed object rises. so the tiny shrinkage of the filament when beeing cooled is more visible when the heating effect from the bed diminishes (guess you're printing without enclosure).

Re: Elephantfoot and layer shift

Hello Prusa Forum,

now i used my printer since one year. The print result was in 0.15mm and 0.20mm fine for me. But I am a perfectionist 😉
I printed the calibration cube in 0.05mm and the pictures show my result.

- The layershifting is probably from the belt tension. But my belts are very tense.
- Regarding the Elephantfoot in the cube, i have no idea..

Do you guys have some help for me please?

Regards
Tim

Too hot.... the lower the layer height, the longer the filament is in the nozzle (slower extrusion) the more heat it gets, the more "melted" it will be. Drop the temps by 5c until it stops, use more fan and / or print slower. There is a setting for going slower if the layers are under a specific time to print.
