Hi everyone, I was wondering if others were seeing this in their top layers as well when printing with Bambu PLA Matte.
Using Monotonic as the top and bottom layer patterns, my large surface area surfaces are seamless, but looking at narrow areas, it seems like there is consistently a seam between each line.
This is at 0.2mm layer height. With the stock settings, I’ve tried increasing the top layer line width, slowing it down to the same speed as the first layer (50mm/s), but to no avail. I’ve also used both auto-flow calibration and manually calibrated flow rate.
I’m seeing this with the hardened steel and stainless steel nozzles with PLA. Not so much PETG HF.
Check and confirm/adjust your flow ratio calibration.
Repeat the k-factor calibration using the pattern.
Pay close attention to those corners and select the one that neither has bulging on the outside nor gaps between the lines.
Do it again but with finer increments around the found k-factor.
Again pick the best result.
Check the infill settings in regards to how much overlap is used.
For large areas it is no problem but for tiny ones a large overlap can produce a build up of filament along the wall.
Do not use ironing on such tiny surface areas in the hopes to get better results…
Unless there is a reason for it do not use a single wall for top layers…
That’s interesting, I haven’t touched K-factor yet…which calibration is that one? I’ll also try not using a single wall for top layers. Interesting that it is on by default, though.
