The pictures explain my problem. I have already tried to reduce the retraction but that showed no effect. Thank you for your help. The effect is a total stop of the print (no material is extruded). Creality CR 10 Cura 3.4.1 I recently added this…

Wear resistant nozzles

I recently purchased some glow-in-the-dark PLA filament (just "because"). Being new to 3D printing, I didn't realize you shouldn't run this type of filament through a standard brass nozzle and should replace it using a "wear resistant" type nozzle.…

Scalable 3D Printer

Is there a definitive scalable 3D printer? I've seen examples of Chinese companies printing entire houses, and I'm curious as to printers / filaments that are intended (or at least able) be scaled up for (very) large print jobs. Since most hobby…

How are delta movements calculated?

On a Cartesian printer movements are really simple. If we assume the printer has 100 steps/mm on each axis, then a move of 10mm on a axis is just 1000 Steps on that axis. Movements that are not aligned with one axis are also simple. Moving from x,y…

Suppose I'm given a shape with a Voronoi pattern, such as this lamp. I'd like to be able to add a "skin" which covers the complete shape on the inner surface so I could print it with translucent material to produce a more-or-less uniform glow. …
