I notice that if I use more than 2 wall loops, the general play and errors in the Z-axis really start to get apparent. 1 loop? Looks fine. 2 loops? I can see a little error here and there. 3 loops? Layer thicknesses really start to get all over the place.
I notice that the wall thicknesses for the default first layer are 0.45 and 0.42 after that with the 0.4mm nozzle for example, if I’m anticipating more passes with my walls, should I reduce that number because of the increased squish?
I can print with a single wall or 10 walls - won’t affect things…
If it does it just means your filament isn’t properly calibrated 
¿Lo has comprobado, realmente has impreso con 10 buches de pared o solo hablas por hablar ?
Every filament has a custom flow dynamic set for it, as well as flow ratio. I don’t mean to be a jerk but post some cubes side by side of 2 walls vs 10. I gaurentee the 2 will look better than the 10.
¿ Imprimir en este orden, pared interior y después pared exterior o imprimir una sola pared que será la exterior mejora el acabado visual exterior de las paredes , mejora la resolución de las paredes más que con dos o más bucles de pared. Porque la punta de la boquilla muy caliente aplasta la línea de pared exterior una sola vez y el calor residual de la punta de ka boquilla funde una sola vez la pared exterior ?
Gracias, y saludos afectuosos desde España. 05/07/2025
Cuanto menos paredes , menos se deformarán estás paredes por la presión de la boquilla y su alta temperatura al.pasar por segunda vez sobre una pared que ya estaba enfurecida y fundirla por segunda vez, lo cual empeora su calidad visual .
Para conseguir máxima calidad visual de pared, imprimir primero pared interior y después pared exterior o bien , imprimir una sola pared.
Estamos hablando de alta resolución, alta calidad visual no de resistencia al impacto, porque cuantas más paredes , más resistencia de la pieza a la rotura.
Saludos.
Generally speaking, if you can get away with it, the exterior wall first gives the best outward finish because the excess becomes the molten interior wall loop’s problem to accomidate or excess is forced upward and then folded inward again on the next layer. The trouble is that printing the exterior wall first can leave you with unsupported exterior wall loops when it comes to overhangs and you require a lot more support use to compensate.
The other issue is warping. Even with good bed adhesion, as you start to stack up layers, they all want to pull in. Sort of like crushing a watermelon with rubberbands. Every so often a bunch of layers will just collectively cave inward, and then the next few layers printed atop the crunch will appear as a bulge before the tension repeats the rippling pattern. 95% of what I see on maker’s world is printed with 2 wall thickness as the profile and I think this is a big part of why - nobody wants to tune for the excess filament squeeze caused by more walls.
This, with timestamp, demonstrates why more wall loops cause more layer unevenness.
You could try outer/inner instead of inner/outer. Looks better, but overhangs can be a little harder.
