Looks like an Ender3 V2 knockoff. Just get the ender 3 v2, it's almost the same price and a very well known brand.

This brand should be quite known these days. They supply the controllers, drivers, and screens all the Ender fans have been upgrading to for years.

Yeah, I bought a drop in replacement board for my ender 3 v1 from these guys (biqu). Older board with TMC 2208 stepper drivers. Worked fine. Sainsmart sells rebranded Ender 3 printers. Looks like sainsmart is selling this too, I'd say it's probably just fine. The design is open source for the printer. Could even be made at the same factory.

I'm still figuring out my ender 3 pro, but wouldn't mind trying one of these printers out.

You would find it to be almost exactly the same. If you want different you need a different design, like a CoreXY etc.

You are correct.

It is a really nice printer so far, with two caveats. Assembly may be challenging for people new to 3D printers. It's not bad, but it is more involved than many others out there. And... the power supply cooling fan is tragically loud. I mean 747 taking off loud! Everything else about this printer is great, but that fan noise is such a simple fix, but so awful.

Is it hard to get access to replace the fan or might be something to do when putting together? Debating on this or the ender 3 v2.

Thinking of getting this. How did you fix the fan noise?

Also, I'm new to 3D printers, but have taken apart and put together a few things in my time (phones, laptops, robot vacuum, etc.). So wondering: are the instructions provided with the unit good enough? Or should I expect to go hunting for assembly instructions online?

Not terrible access before assembly and certainly harder once it is set up. You have to remove the bottom panel and the fan in question is on the right side just in front of the gantry. I am still diaing it in and have no regrets about getting it over an Ender. Debating on using one of the 12v fans I have and adding a buck converter or getting a 24v fan. I'll probably try out the buck converter and order a thermal switch to put in the terroid so it will only run when it gets warm. I have that on another printer and it is pretty unobtrusive.

Thx. For those wanting more info on the fan replacements. Good post on Reddit.

The fan noise is a work in progress. I'll get it there one way or another, I'm running a 16 hour print on it now or I would be fiddling with it. Decided to put up with the noise just to get that print done and see how it looks.

The instructions aren't great. There have been minor design changes to production units not covered in the printed instructions. I honestly didn't look at the SD card to see if they were updated there. They don't really cover the importance of loose assembly and final tightening to square it properly. I put a drop of PTFE oil in the bearings and work it in and lubed the lead screw lightly. Little things like making sure the eccentric rollers are properly adjusted can make a big difference in print quality.

If you think logically about it it isn't hard to assemble with the given printed instructions. Just remember it's not a race and double check the already assembled sections.
