Nozzle is hitting the layers (infill) at full speed. (V-Minion)
I am having weird issue and was wondering what mechanics or software is behind it.
When I am printing long rectangle in diagonal orientation after few layers (approx. 5mm height) nozzle start to hit the layers of infill and after another few layers its that bad that it actually starts to rip of the infill lines (cubic, line, rectilinear were tested).
When i slow down the printer to 75% everything starts to work absolutely great and even the ripped parts are repaired and print is finished without any issue.
PS: I was printing "IKEA Skadis T-Handle Hexkey holder"
Any thoughts what could be the issue here? I don't mind to set the printer for 75% of speed its still quite fast and prints are good, but just wondering out of curiosity.
Ill post some pictures tomorrow, since I forgot bad parts in office. 😄

Maybe simple over extrusion? Did you make EM calibration?

I did pressure advance etc... but not the EM for the slicer. i am working with original preset for v-minion and petg which is 0,94

Do proper EM calibration to remove this out of equation

thank you.
Ok, it looks like it should be 0,92 so 2% less then initial setup. ill try to test print with this setup.

Since I am using prusaslicer i did it with https://help.prusa3d.com/article/extrusion-multiplier-calibration_2257 - precise method. 😉

This is an advanced calibration, recommended only to experienced…
