MK4 Bed Adherence

Hi, appreciate +++ the community here and forum discussion. I'm new to 3D printing but understand the principles of bed adherence quite well. Here are the facts:

1. New MK4 printer (1 month old). Printing on Satin Sheet. Cleaned with 99% IPA. 

2. Prusa Alpaca test piece printed flawlessly.

3. Downloaded STL file from Printables.com (cover for Catan card box). File was originally created for an Ender printer.

4. Sliced file with Prusa Slicer and G-Code indicates no errors.

5. Main body of print adheres well to Satin Sheet. BUT: Thin connecting arms are stringy, stranded, spaghetti. No adherence. See pics.

6. Options include: Change nozzle height, increase heat bed temp, increase nozzle temp, reduce fan speed, reduce nozzle speed.

QUESTION: If Prusa Slicer indicates no errors, are there any methods of identifying the best problem solving sequence? (i.e. first order changes for higher probability fixes)

Thank you!

First, don't clean build plates with anything EXCEPT water and soap UNLESS you have a real reason to. So far, you don't. Second, use gluestick. Don't change any nozzle height. That is set automatically. Over time, you will learn how to get things to stick without much glue, but now its good to use.

For such thin parts you want to use brim https://help.prusa3d.com/article/skirt-and-brim_133969#brim

See my GitHub and printables.com for some 3d stuff that you may like.

Echo the above - I would use a brim

I concur with the brim.

Besides, if that filament is PLA, a smooth sheet will provide better adhesion than the satin or textured. That's specially useful printing parts with steep overhangs and/or a small contact area with the bed.  An alternative solution is to use adhesive. I don't like glue stick at all. There're better options, mostly based on hairspray (3Dlac, Laverneer..).
