Printing with 0.25 nozzle - "waved" print...?
Hi Everyone!
I'm new to the 3d printing scene, so.... please be gentle 😊 .
I've swapped the MK4S factory 0.4mm nozzle with a Prusa Brass 0.25mm nozzle ( https://www.prusa3d.com/product/prusa-nozzle-brass-0-25-mm/), as I was curious if it can give more detail for the same filament type.
So, I printed a "Fillennium Malcon" ( https://www.thingiverse.com/thing:919475) using both nozzles using the default print settings (profiles) available in the Prusa Slicer:
- Prusa Slicer 2.8.1.
- 0.4mm at 0.1mm FAST DETAIL profile
- Added "Support on build plate only"
- 0.25mm at 0.05mm DETAIL profile
- Added "Support on build plate only"
- PLA - Made for Prusa Silver ( https://www.prusa3d.com/product/silver-pla-filament-1kg/)
Ignoring the print times, as they will obviously differ massively, I got a... "dent"... "bump".... "wave" at the end of the print with the 0.25 nozzle.
So... the questions are...
- Why?
- Why there?
- What did I do wrong?
Any insight is greatly appreciated and "Thanks in advance!" is obviously needed. 😊

Well they're here now 🙂
If you print it in the orientation set in the stl files provided a tall, narrow print like this is going to wobble - the area in contact with the build sheet is small ... try rotating it 90° in the Z plane so that the Y axis movement is better resisted and print it slowly - use a Quality setting and slow it down by 25%
Cheerio,

Thanks for the insight!
In both cases it was rotated by 90 degrees, so the Y (bed) movement would not affect the contact and topple it.
I do seem to see that by the end of the print, the top part is pretty much back where it should be... so I'm curious if that's "normal". Did the printer correct the offset or was it a mechanical error... I'm still wondering why there and not anywhere else.
Slow it down... man... it took 22 hours to print it scaled down to 60% (~12cm long). If I'm reprinting this model and slowing it down, my grandkids (which I don't have) will see it finish printing 😀
Jokes aside, which options should be slowed down, as there are quite a few of them...?
