Short story: a model printed multiple times (20x-30x) with almost 100% succes rate on my old machines (Anycubic Mega S + Prusa Mk3S) has 5 failed prints on P1S.
What happens: the nozzle collides with the vertical walls and displaces or brakes them!
The main container for these models is:
The model discussed is Product 10_15x25 - smallest ring(10x) from largest type (15x25) Product 10_15x25_AllCATPart.3mf (1.9 MO)
Without solutions, I have installed even Orca slicer - but it looks to be 99,9% Bambu Studio and of course I got the same poor result - broken moved vertical walls:
My only explanation is the clearly defined Z-Lift parameter from Prusa Sllicer - of course on BL P1S we have a Z-minus hotplate displacement but I could not find it anywhere.
Thank you! A bit hidden there, slightly different naming, but should be the same action in fact.
I have progressed with the issue - my previous statement that the displacements are the result of collisions with the nozzle is most likely incorrect - I have set my (heavily modified) Anycubic machine to run at 150% print speed and I got also wall displacement problems…
The print goes 100% OK up to the top bridging layer. The slicer notices the multiple bridges with changed angle and intends to build these bridges on shortest distance for each element - this is a great thing - ion the spirit of Simplify3D
But moving the printing head for each of these bridging positions, in one layer it travels without new retractions and without Z lift!
I honestly did not expect to see in 2024 a popular slicer colliding the geometry it just printed…
- just a design with inertia issues…
