Can’t figure this out

Check the sliced previews. More specifically the layer time, flow, and speed previews. If your layer time preview has the same pattern, try changing your infill type to rectilinear. Check the preview again. If it looks even, or better than it was, try printing it to see if the banding goes away. Sou

Can't post it on r/3dprinting till monday, so I'm putting it here

All printers have their place. For mass production my Bambus are my go to but for prototyping my FLSun S1 pro is by far the better machine

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.

The FLSUN S1 promises speed but the print quality is poor. What should I do?

Install Viking3DK Orca profiles to get high print quality. https://www.printables.com/model/1426214-flsun-s1-s1pro-orca-profiles-v10/related

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

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

I just love this coaster/can holder! 🤩

Hej Smoker aka Viking aka u/Smokerdude420_DK Jeg faldt lige over din profil på r/FLSUNDelta .. Jeg købte en FLSUN S1 Pro for to uger siden, jeg fik en cuponcode til deres EU side så den kom ned til 650€ , det virkede som et godt tilbud. Jeg har kigget på at købe en printer en gang i mellem de sidste
