S1 Pro Black Friday Deal
I have had 3 different FLSUN machines, and they were all DEFECTIVE. The support doesn’t give a f*** either. I’m returning my defective s1 pro and getting a p2s combo. DO NOT BUY FLSUN

Months of FLSUN hell — T1 Pro failed, S1 Pro arrived defective, now both FLSUN and Micro Center refuse my refund
It sucks when companies shirt blame to others. Sorry you’re struggling with that. I’ve heard filing a consumer protection claim with your states attorney general or similar will often get companies to do the right thing to avoid hassle. I have to ask though, looking at the FLSUN S1 on Microcenter an

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

Help: Flsun deletes my Facebook posts!
I commented on a post yesterday lamenting on parts availability for the S1 Pro. Admin is an FLSUN employee it seems, so he had me message him. He located parts for me. There’s more to this if they keep deleting your posts, or I’m just obscenely lucky with my customer support experiences with them so

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

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
