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

FLSUN S1 - FREE
I have an S1 pro and I'm feeling the same. Not quite giving it away yet, but I'm on effector #3 and it worked all of 1 second before getting a clog that required full disassembly. FLSUN support hasn't responded to my email (it's been weeks). Printer has been down probably 8.5 of the ten months I've

Give me your opinions on the FLSun S1
DO NOT BUY THE DAMN S1. THE PRINTER SUCKS, THE COMPANY SCAMS YOU AND ITS A WASTE OF MONEY. I bought my first FLSUN back in December and it was the t1. It broke a couple months in. The replacement t1 pro broke in a month and the so called upgrade the s1 pro has been defective since arrival. I’m buyin

Help, replace effector s1
If anybody has a broken S1 Pro effector they want to give away, I need one badly. Flsun has been out of stock for several weeks. I would like to rebuild a workable effector from 1 or 2 broken effectors. I'm just getting frustrated how long it takes Flsun support to get back to me. PM if possible or

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

This thing 😡 (S1)
the extruder can be opened and cleared of clog, done it a couple of times. The investment in time to do it seems a reason to stop using my S1 Pro. I figure the parts alone is worth something. When they were available, I bought a new extruder as a spare. shame on FLSUN for not doing the support for a

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
