I am using PLA, i change the speed temperature and i still have gaps in the final product, what can i do to solve this problem?
Can you try with à new pla ?sometimes if there is humidity in your filament, you can have this… Or bad filament quality…
Binding with your filament maybe? Skipping feeder
Looks like higher temp, faster feed rate, maybe increase vertical resolution.
i would agree with @Slobber_bone high temp leads to bubbles from humidity. (also retraction settings can cause voids) try (slow) print with low temp - dry you filament in an oven (must not exceed 60°C). Higher speed can also minimize this as the filament passing the hot zone faster so bubbles can’t develop. But if testing with low temp a high speed may cause mechanical issues within the extruder.
Enlarged, it also appears that the layers are a bit touched together. This is under extrusion. The shortage may be plugging or weak spring force in the extruder and the thread stumbles.
Calibrate the extrusion. There are many videos on youtube.
Check for tugging on the spool of filament. Looks like something is intermittently causing stoppage of flow. Is this happening on every layer?
Your Z axis steps/mm could be wrong… Double check via Pronterface or similar to move 100mm and actually measure the distance travelled on your Z axis. I had a similar issue when I upgraded my firmware and stepper driver…
@ThantiK not in every layer
Maybe layer thikness?
That may be over retraction…
Was the last good print in a different filament and if so, what filament?
This is all I am asking because others just about covered most questions.
I had a similar effect on my hictop, I ended up printing a few degrees higher and added an oiler to clean the filament before it enters the extruder.
Instead of guessing when you’re printing, it helps a lot.
Hmmm…nobody mention filament diameter inconsistencies or dusty filament spools. I just figured I would add them for completeness.
@NathanielStenzel We did not think it because the uneven fiber thickness does not cause a loss, only uneven layers. We thought about it, I wrote that it could be a clogged.
This guess makes no sense. We have listed everything. It’s a good idea if the printer’s owner carefully monitors the printer while making the mistakes.
It’s like a doctor remotely finds out the illness so he does not see the patient …
@Jakab_Gipsz but a novice can learn a lot from all these guesses - to understand the influence of all these factors and to what he needs to pay attention to when printing.
When a person posts asking for help, people will rarely know how experienced the poster is. People rarely post enough information. Some will make assumptions.
@Cameron_Spiller I am using slicer too, i think the calibration its the cause of the bad printing
