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

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

Ended up getting 3 more 😁😂
So, what you're tellin' me pard is that you "...don't have the space for a mid room table..." because you've already got FIFTEEN FLSun printers taking up that space. Good on you. I've got an even 24 printers in my wee farm but only 2 T1 Pros and 2 S1 Pros in the lot. But I've been vacillating betwee

Which one to get?
There is no reason to get the s1 pro. Everything is integrated and proprietary. So you can't upgrade it. And you can only buy parts for it through flsun. With their history of dropping their old products when they release new ones. You have a paperweight in 3 years. Plus, none of the AI features wor
