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

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

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

Just bought an S1

I have a S1 Pro and it has been pretty solid. I would highly recommend getting "high speed" filaments. I have had good luck with Sunlu's HS PLA and Elegoo's Rapid PETG with just default profiles (using OrcaSlicer). I haven't used other filament types outside of that. Be prepared for how loud it is.
