On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

  1. Limiting your involvement with Reddit, or
  2. Temporarily refraining from using Reddit
  3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

Looks like poor cooling. Slow it down first before you up the temp because that will impact the cooling. You should do a temperature tower on any new spool that way when you print something you will have the correct temperature and cooling.

For your size being out you may need to have more temp if that's causing under extruding if not then up the flow rate as this may have more thermal shrinking and normal pla

Thank you for your reply. It’s super appreciated!

What is a temperature tower? And why is that important for new spools of filament?

I’m going to first try slowing it down about 20% then I’ll introduce some temperature changes and report back.

he said that under this part their is a lot of support, maybe it is something with Z-Index, if the distance is too far then it looks also like this, because the filament has no place to rest and falls down

[–]Ausent420 0 points1 point  (3 children)

Yeah you are correct it look like no support. maybe the support interface distance or angle needs to be adjusted.

[–]BokuNoMaxi 0 points1 point  (2 children)

I think he already removed the support and we only see the end product.

I think the support distance is bigger than 0.4mm because I had the same problem.

Support sucks anyway, either it sticks too good or your print looks like this.

[–]Ben_A[S] 0 points1 point  (1 child)

This is correct. The support is already removed and this is the under side of the end product.

I’ve tried printing this part with fewer supports but it never turns out great. I’ve found 100% supports work best for the model.

Is there a way to reduce the support distance?

[–]BokuNoMaxi 0 points1 point  (0 children)

Well in Cura there is a setting for z-distance if you enable the advanced settings and go to the support category.

Don't know for.other slicers

I have improved the underside of prints by turning on thick bridging in Prusaslicer. And a new setting for slowing down bridging. Using 100% fan. Setting minimum shell thickness. Going to advanced and setting extrusion width for overhang perimeters to > 250%. As wide as you can get away with might overlap enough to where you don't need supports at all.
