I don't particularly recommend the following, but it may be easier than 0scar's answer (which I would recommend implementing if you use Cura). Slice your object twice, once at the lower infill and ...

All the Prusa-based designs I've seen have only one end stop. While you are correct that it's theoretically possible for the two Z-drives to get out of sync, it's very unlikely in practice (barring ...

What exactly does automatic bed leveling do?
Accepted answer

Last first: use of a raft has nothing to do with bed levelling. It depends only on the features/shape/etc of the object being printed. Now, as to what the auto-levelling does: the answer is, sadly "...

Does Cura have an algorithm for any infill percentage or does it just have specific patterns?
5 votes

I fear I'm going to deny your question. The infil percentage and the infil pattern are two orthogonal properties, both of which contribute to the strength, density, mass, and print time of an object. ...

(Cura setting) How can I fix this? No top layer

I'm pretty sure the yellow lines are showing the full path of the extruder head, including where it's retracted. Somewhere in Cura's maze of menus, there's an option to turn on/off various displays ...

Given the tendancy for extrusion 3D prints to be porous, aside from any potential health/ingestion issues, I'd recommend lining your pots after printing. You could use an epoxy that's food-rated, or a ...
