What is a masterspool?

Recently, I have heard people talking about masterspool, when talking about 3D printing filament. What exactly is master spool? Where did the idea come from and when? Is it being widely adopted? Or to be specific, how many…

What printer is this?

I've been watching this video 3D printing guides: Calibration and why you might be doing it wrong and at the start (at 0:30) three of the first Reprap printers are mentioned (and shown): Darwin; Prusa Mendel, and; what sounds to be "Cells". Here…

But ... skateboard bearings have OIL in them, and oil is ... bad?

I see plans for various spool holders, either for PLA in the open, or for whatever filament in a dry box, that use 608 bearings. Elsewhere, I see warnings not to oil your filament to make it go through the extruder better, because problems going…

Is the 110 m length accurate for 3.0 mm 1 kg spool?

I've been seeing the 330 m and 110 m length estimates for 1.75 and 3.0 mm spools (of PLA, presumably). But a moment's thought staring at that will raise an obvious question. Using πr², we get the area of the filament in square millimeters (rounding…

First layer of print comes out poorly even when placed on a raft (which prints fine)

I'm printing PLA with the Creality Ender 2 and my print comes out totally fine with the exception of the first layer. Here's the weird part though, if I place a raft or a brim below/around the print - the raft or brim will print perfectly cleanly.…

Cura confused as to what's touching the buildplate?

I'm very new to 3D printing, but so far I've been able to print a couple things off Thingiverse without issue. However, as I'm trying to print another part, I've run into a situation where Cura is totally confused as to what's touching the…

Z-Axis doesn't work only during printing

Problem: Z-Axis doesn't work during a print. It attempts to work, maybe climbs on the Z-Axis, but screws back down. It whines, too. But, Z-Axis DOES work while not printing. It doesn't matter if the bed and nozzle heating or not, if it's not…

Anet A8 Hotbed Not Heating Correctly

For my Anet A8 I replaced the stock power supply 12V/20A with a eTopxizu 12V/30A, plus I added a fused 250V/10A power switch and mosfet. The issue that I am having involves the hotbed, it has no issue heating up, but it doesn't heat up past 94…

Cooling fan spins extremely fast, noisy on startup

I have built a 3D printer from parts. It is using a standard 12V power supply, an Arduino Mega 2560 replica and a RAMPS 1.4 board. The hotend cooling fan is connected to the 12V-AUX pin (the one right next to the x axis stepper driver) on the RAMPS…
