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

H2S opinion
I was this 🤏 close to preordering it. I got burned on the QIDI plus 4 and Flsun s1 pro, so I’m hesitant to preorder any new klipper printers these days. I sew that. Don’t worry, it wasn’t me.

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

SV08 Max questions
I own one. Out of the following brands ive bought. Bambu, flsun, elegoo, anycubic, and sovol. Sovol is the 2nd best imo. It does have vfas though. Im not a huge tuner and cant tell you if it van be tuned out easily. But part quality pit of the box is pretty good. This is compared to an elegoo neptun

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

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

Which one to get?
At that price, I would go for the s1 pro. I dont think they're worth the 999+ flsun are selling them for, but at 499, I would pick up one or two

Fast printer under 1300 euros ?
For PCCF, I'd recommend the Qidi q2. Its better set up to handle abrasives and more demanding filaments that require a heated chamber. The hotend reaches up to 370C, the bed up to 120C, the actively heated chamber up to 65C. Although, if you are solely after speed, nothing beats the delta printers m
