What options exist for augmenting the automatic bed-leveling?

When I print this file, one section smears. The print head is dragged through the soft filament. At first I thought my aluminum bed was warped, so I upgraded to a glass bed. Test prints were much better, but still had a section that smeared. My…

Good filament/s for heat resistance in cars

I have designed a cupholder for my center console in my truck with PETG. I was hoping it wouldn't deform and it didn't for a while but we got some high temperatures the past few days (around 32-38 °C or 90-100 °F). Kind of figured it wouldn't hold…

Why is my Ender 3 restarting spontaneously in mid print?

tl;dr How can I test whether my sporadic in-print restarts are a thermal problem or a firmware issue? The problem I've had my Ender 3 (not V2 or Pro) for about a month, and gotten a number of excellent small prints with Amazon Basics and SunLu PLA,…

Can I print my own Lego bricks?

Assuming I've 3D design (or I've created one) which looks very similar to Lego bricks, I am allowed to 3D print them for my personal use? Do I need to obtain some permission to do so, because of some patents? Or how does it work?

What ambient humidity should one target for filament storage?

I live in an arid environment and have never worried about leaving filament out for an extended period of time. To reduce how frequently we receive static shocks I installed a whole house humidifier with a target humidity of 35 %. Is this enough…

Cloning the Marlin git repo while keeping my configuration.h settings?

I cloned the Marlin repository and changed all my settings in configuration.h to match my old settings. Now when the RC branch gets updated, is there a way to upstream pull the changes without losing my settings?

How to get less Z-seam?

I printed this Curvy vase from Thingiverse and it came out pretty well on my Chiron. However, I am not happy with the Z-seam that is very large. When I look at other people's problems with this, they often seem to have too little filament at the…

Do I have to buy all new components if I were to get a RAMPS 1.4 that supports 24 V power?

Ryan Carlyle seems to keep suggesting in my questions here, that using a 24 V power supply is safer than using a 12 V one. Early on, I ordered the wrong power supply, obtaining a 24 V one instead of a 12 V; I found that it was incompatible with my…

How to treat PLA (Polylactic acid) plastic to make it biodegradable?

I am using PLA for 3D printing, and I know it does not degrade well in the wild. I would like to know if there is a chemical process I could use to treat it at home. Specifically, I am looking for a cleaner alternative than throwing my 3d printing…

What is the influence of a lower BAUDrate?

I am using a BAUDrate of 115200 since I cannot make a connection to my printer with the advised 250000 rate. Are there any downsides or limits I reach earlier given by the lower BAUDrate?

Why is pressure advance usually implemented in firmware rather than in the slicer?

Recently I started looking at pressure advance and how it works and I'm a bit confused about where it is usually implemented. My idea of 3D printer was that its firmware is fairly dumb and only replays G-code, not knowing anything about the object…
