My experience has been totally different than yours, but also our circumstances are different. I have about 2,500 hrs on each of my 3 P2S’s. I print exclusively PETG-HF and have installed high flow nozzles in each machine. I typically have them running 18 hrs a day. Once I got my initial settings dialed in I’ve been extremely pleased with these machines (I just bought another one). Nothing but normal routine maintenance needed. But like I said, our circumstances are different. My ambient room temperature is around 25 degrees C. I keep my filament dry (under 12% RH), and I clean the build plates between each print. Clean the nozzles around every 10 prints. Had 1 pully one time squeaking but a little silicon grease took care of it. I came from P1S and had 4 machines. Put about 4,000 hrs on them and sold them. In my opinion the P2S is a much better machine and I would recommend it to anyone doing high volume printing.
Sage advice. I have had some problems but since I understand the variables of 3D printing? Coming from a Artillary Sidewinder 2? Yea I will take this experience over what I have been dealing with for the last 4 years. Thes things are tanks and I love them!
That makes hope that either there is just something wrong with my machine or I am just not doing it right. Honestly, I d prefer the latter. Your room temperatures are equal to mine, so is my bonedry filament. I also tried PETG-HF which went way better than PLA+, but I just tried one model that was pretty much a technical, very squared model with less to no overhangs.
Anyway, thanks for your feedback. Much appreciated.
I’m far from being an expert, and I certainly wouldn’t claim to understand all the complex parameters involved in 3D printing. But I’d also consider myself a bit beyond the complete beginner stage. I spent about 20 months with an A1 Mini and learned quite a lot along the way.
Maybe that isn’t the right reference point when it comes to expectations for a machine that costs more than three times as much. And perhaps it isn’t entirely fair to compare a bed slinger with an enclosed CoreXY machine either.
Most user reports seem to lean in the same direction as yours: a great machine without any major flaws, a real workhorse that simply runs reliably. Which is exactly what keeps me wondering: why is my machine so different?
There are certainly hiccups, flaws, and bugs — and they are well documented, even if some people would rather pretend they didn’t exist 
See the footer of my Gist for links to GitHub firmware issues and more.
But honestly, I wouldn’t care too much about any of that if my actual print results weren’t slowly giving me grey hair.
