Let's address the elephant in the room: around 150 euros. After two months with the Anet ET4 Pro, in March 2021, here's my honest experience. It's not perfect, and it needs some care, but if you tune it, it delivers.
A printer that came back from a return
I got this printer in a funny way. Anet told me an Italian customer had bought one, couldn't get it to work, and returned it a week later. Did I want it? Sure. When it arrived it had a few problems: it wouldn't read the SD card, the pneumatic fitting on the extruder was broken, and later I found the fan wasn't working either.
For an experienced maker that's everyday maintenance. But it's exactly why the customer gave up, and why I say this printer isn't aimed at complete beginners.
Specs
Silent stepper drivers, auto bed levelling (I tried it a couple of times and went back to manual, which works much better), 10–15 minutes of assembly from three pieces, 220 × 220 × 250 mm build volume, a Bowden extruder, a glass bed plus an included magnetic sheet, power-loss recovery and a filament sensor. The touchscreen interface is intuitive, with three main commands.
Fixing the cooling
The pre-sliced model on the SD card (again with a crazy ~80% infill) already showed a cooling problem. My first Benchy and a dinosaur showed the same thing: the plastic just wasn't cooling. I replaced the small fan with one I bought at a local Chinese electronics shop, and from then on it printed really nicely. I also tweaked how it homes and starts the print by editing the start G-code in Cura.
This was my third printer, so I knew how to tighten the bed and the bolts. After a bunch of failed prints, my first perfect Benchy came out flawless. Once tuned, it became a reliable PLA printer: I slice, start it and leave the room.
Slow and steady wins
A low-poly fox in silk green, a sausage dog, a Spider-Man (sorry for the pen lines, my kid drew on it). What I love most is that at low speed it prints beautiful vases. My house was full of them, mostly from this printer. My advice: don't go above 40 mm/s. Speed it up and you'll probably have issues.
I printed a few upgrades in AzureFilm Neon Lime PETG: a filament guide, a knob, a Y-endstop cover and a bed cable holder so it doesn't wobble. It became my second main printer, the one I trust for long, slow jobs.
