3D printer table
Vibration isn't relevant on modern printers with input shaping. I have my q2 on this table along with my flsun s1 pro, I have no issues. Even with both printers working at the same time.

give me your honest reviews of FLSUN
I love my S1 Pro, though it took a week of dialing in and figuring out settings to make it print at a similar quality to my Bambu A1 Mini. But once that was figured out, it’s been great! Print quality is fantastic and it’s so fast, even with my setting tuned to favor print quality! One thing I’ve ex

S1 OR S1 PRO
AI to the rescue The FLSUN S1 and S1 Pro are both high-speed delta 3D printers, and they share many core features. However, the S1 Pro is an updated version that brings several key improvements and refinements. Think of it less as a complete overhaul and more as an "S1.5" with enhancements that impr

THANKS FLSUN!!
I have 2 FLsun S1 Pros. Awesome capability at a very low price. Require more hands-on attention and maintenance. And I have ordered plenty of Spares in advance. Customer service has been good when needed, but very slow - like several days for a simple email exchange. But. The printer, parts and serv

Im still amazed in how great the V400 is! 🥳
Hopefully flsun will get the firmware right with the T1 and S1 pros soon. They have great potential. The V400 is a beast, that just keeps os going. Hoping to get me T1pros to the same quality

Another what printer should I buy thread.
If you want a very fun and extremely fast printer though, check out the flsun s1 pro. It's the fastest consumer-grade 3d printer, costs $1500, and is a delta printer so it looks very cool. I have to warn you though, flsun printers have shit quality control, so there is like a 15% chance you get a pr

I love my S1PRO that much that I bought a second one 🤭. And I havent changed that much, I just installed the Open Source Klipperversion by Cyril Guislain, wich is originally for S1, but works on the S1PRO too. Thigthend all screws after unpacking, and thats it. If yours is a S1 I would look on Flsun

FLSUN S1 - FREE
If I lived anywhere near Charlston, S.C. I'd be taking you up on your kind offer. I only have 2 (two) S1 Pro's in my farm but, they both work flawlessly. In fact, most of my FLsun printers are my go-to for fast turnaround. Of course I've also spent time with the machines ( and not just lazy plug & p
