Hello, I am experiencing the issues you can see in the photos. I have searched on this and other forums but haven’t been able to find a solution.
Could anyone guide me on trying any possible fixes?
I have a P1S, I am using regular PLA, and I can never get a proper final layer; it’s quite frustrating.
I also show you the profile and settings I am using.
If you need anything else, don’t hesitate to ask!
Thank you very much for your help.
How is the part oriented on the build plate in relation to the Aux fan? (Either post the 3mf file or show a screenshot of the part in the slicer.
Can you please post photo’s of the underside (build plate side) of the part.
General observations/recommendation
Material flow rate seems high so a flow rate calibration is highly recommended.
Chances are high that your part warped and became detached from the build plate in that corner and that is the number one failure par none in 3D FDM printing so ensure that your build plate is super clean prior to each print
Thank you very much for your quick response and for trying to help me.
I’m attaching a photo of how the piece is oriented.
Right now, I am following your advice to recalibrate the flow of that material.
Any help you can think of will be greatly appreciated.
Ok so that problem corner is close to the aux fan therefore aside from the flow rate calibration you can also try a customized filament profile with a lower Aux fan speed and/or re-orient the part so that the high wall portion faces the aux fan.
Alright, I’m going to try your solutions to see if I can get the same piece perfect, and I’ll keep you updated.
The marks I’m pointing out in this photo, are they caused by the same issue? Or is this a different problem?
Once again, I’m very grateful for your help.
These lines are from too high of a material flow rate where two sections in the layer are being joined together. Observe while printing and you may understand it better
