Recommendation, H2S vs P2S vs K2 Plus. Or something else?

I bought the H2S on the day it was released to properly scratch my functional filaments itch (it was possible on my X1C but demanded a bit of attention to fans, passive chamber heating etc. for success). The H2S just deals with everything I throw at it with zero issues. ‘Download, slice, print, wait until finished’ regardless of the material. I’ve printed several kg of ABS-GF and PETG-GF via the AMS2P and 0.4 HF nozzle with zero issues - I just skip through the ‘brittle filaments’ AMS warnings and ‘0.4mm HF nozzle’ warnings and off she goes every time. 3d printing is just something I do to support my main hobby (woodworking), so I don’t have the interest or the time to waste on playing around with what BL have effectively turned into an appliance. Highly recommend the H2S.

I Tested 3 3D Printers! Which is best?!

This printer was one of three single tool head printers compared for out-of-box print quality using generic filament profiles. The specific performance results for this printer were not revealed in the provided transcript.

About to buy a H2S

I have an H2S, I recommend getting at least the H2D for your use case and skipping the laser entirely. Why H2D: The H2S takes longer to switch filaments than a dual nozzle printer or a multi-nozzle printer liker the H2S, meaning multicolor prints take significantly longer. They also generate purge waste, which is annoying and adds up the more colors or materials you want to use. Even if you settle and say "Okay, I just won't do multicolor", this still doesn't help because supports are another major use case for multi material. You will get far, far cleaner prints and support removing experiences if you can use an interface material, but this also counts as a filament change. I got an H2S as my first Serious Printer after messing around with printing years ago on cheaper machines, and I am now upgrading it (with the Vortek kit) to an H2C. I regret that I did not originally buy an H2D. Why not laser: IMO combining laser cutting and 3D printing in one device is a terrible idea; just because the hardware can, doesn't mean it should. The reason is straightforward, you get a lot more wear & tear and accumulation of soot and smoke residues and such. Go read the article on H2 maintenance/cleaning and then imagine how much harder it would be if you had to clean out smoke residues. Ever seen the inside of a well-used smoker? Yeah... you get the idea. TL;DR Save the money on the H2S Laser and get the H2D AMS combo instead, it's on sale for the same price. If I was smart I would've bought the H2D instead of an H2S.

H2S vs X1C vs P1S — We Own All 3 (Early Comparison)

The H2S is the newest and largest printer in their lineup, offering significantly more build volume, faster speeds, and quieter operation compared to the X1C and P1S, making it the top recommendation for capability.

Flashforge AD5X What your thoughts junk or okay or beginners

The best so far has layer shifts. It was the best looking of all the failures, but structurally it's garbage. We have 3 at the shop.   They work well for pla.  Work the new h2s I've burned an entire roll of pa6cf in the last week,  non stop bad prints.   The best so far has layer shifts. It was the best looking of all the failures,  but structurally it's garbage.
