Bed too close to nozzle?

I've been having some bed adhesion problems that I have been trying to solve by leveling the bed. I think that it's pretty level now but when I start a print the lines seem pretty flat. Is this true? I used a feeler gauge to have a 0.2 mm gap…

Z-Axis does not appear to be working on Ender-3 Pro

So, the wife got me a Creality Ender-3 Pro 3d Printer for Christmas. Assembly was easy, axis movements are all solid... when I go to print the test-dog.gcode file provided with the machine, it comes out looking... flat. Not kind of flat. TOTALLY…

Considerations when pausing a print job

Some prints take a long time and, as I'm not in a workshop, I need to pause the print sometimes. Are there any special considerations I should take when pausing, or can I literally just click pause, leave it for twelve hours or so, and it'll…

It is worthwhile to protect electronics with a 3D printed PLA case?

PLA is flammable, but a good case can protect the main board from dirt. Is it worthwhile to protect a circuit board with a 3d printed case?

Messy top layer with PETG filament?

I'm having issues getting PETG to print nicely. I have encountered pretty much every issue because when I fix one thing another issue pops up. I see people saying that you should "just copy your PLA settings", but that definitely did not work for…

First time assemble of Anet A6 printer. Only fan works

I bought an Anet A6-L printer (after some research I discovered that this is not a genuine Anet A6) and assembled it. The first time I plugged it in, the fan (fan 2, I believe) is the only thing that turns on. Also, the LCD screen (LCD2004 5 button…

Does color changing PLA require a hardened nozzle?

I've seen comments about glow-in-the-dark filament being abrasive and would damage a bronze nozzle so a hardened nozzle is recommended. Is the same true for filament that changes colour when warm (for example when held in your hands)?

Can the filament tube be outside of the nozzle?

I bought a few new nozzles expecting them to come with that little tube that comes out of the nozzle. They didn't come with them after all, so I tried to reuse the tube I originally had in the printer. Turns out my old tube is 4mm OD and 2mm ID, but…

Getting worse quality prints on 0.05 mm than on 0.10 mm layer height on Prusa i3 MK3

I have a new Prusa i3 MK3 and I have noticed that my prints consistently turn out worse on 0.05 mm layer heights than on 0.10 mm. The edges of the 0.05 mm prints turn out rough and sometimes stringy. Seems similar to a retraction problem but I…

Triangulation adapted to curvature

I don't know whether this belongs here (where most of the questions appear to be about hardware) or on Math or on Blender (though I've never used Blender). All of the designs that I've published so far consist of grids of bent ‘rods’, and in most of…

Adding additional extrusion to a raft (raft with a skirt?)

I started using rafts more often, to get better results with complex or fragile parts, but my Ender 3 consistently under-extrudes the initial outside line of the raft (for the first inch or two, where extrusion starts). It is often very thin and…
