Need help with 3 d printing problem from anyone that can help.

[Raymond Gaskins]

See my posts to 3d seagull for details. I am so new to using the forum that I may not know how to be noticed and am possibly hidden in the thread. I have searched many sources to answer my questions about thin walled printing and have exhausted my empiric attempts without success.
Thanks to those with experience. Now using Prusa Mk 3 printer. Using Curi slicer. jpgs I posted illustrate the problems with persistent pin holes in the prints and larger holes in the z axis near completion of the print despite the PlanePrint wing trial prints coming out perfect.
Thanks in advance to anyone willing and able to help or even to point me to other sources of information. I have viewed a number of YouTube videos on this topic but find this method of learning very time consuming and of little help. What I need is an explanation of how prime retraction distance, speed and extra prime relate to each other and how to best adjust these variables and others to get rid of the pinholes and defects near the end of my thin wall prints near the completion of the print in the z axis. This is occurring only in the profile 3 surface prints from PlanePrint.
Thanks,
Raymond

Raymond, What filiament are you using, and what temperature are you using in the nozzle?

 

[Raymond Gaskins]

Polymaker PLA+ And nozzle temp 223 degrees

 

[Raymond Gaskins]

Actually, temp is 221 degrees C

Raymond,
I had similar problems with my wing sections of the ASK-14, I found that a nozzle temp of 230 worked best
for all of the sections. Also I found that to stabilize the tall thin sections I added a BRIM at the base, and located
all SEAMS to the back of the Part. I also reduced the speed, which eliminated a lot of the weird stuff. I am also
using PLA filaments.

Thank you for your help. I will try these adjustments and let you know how the work.

Just as a heads up, temp sensors on printers can be off.. Some playing to find the right number may be required.

About 2/3 finished assembly on my Prusa Mk3s kit. Taking me about twice as long as as manual estimates. Parts quality and fit superb but lots of tiny screws and nuts to place. Very challenging for my 72 yo eyes. Think I am going to like this better than my Bowden tube AnyCubic Vyper. Then will try to fine tune my ASK-14 remaining parts and assemble and fly it.
Appreciate the tips from all who have helped.
Just looking at Rafael’s Seagull gives me inspiration.

All finished on the Prusa Mk 3s+ except connecting a few more cables and plugging in and hoping not to let any smoke out! Spent about 30 hours this Friday, Saturday and Sunday with the assembly. My time is about 3 times longer than the instruction manual stated, possibly due to visual challenges and arthritis in my hands. But, I saved $250 by doing it myself so I can buy more goodies from Aloft
