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

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 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

T1 Pro Burnt Motherboard
That is a 2.3 board with the 35V caps. Try and replace with 2.4 board with 50V caps. The early T1 Pro pre orders had S1 Pro silver CPAP and 2.3 boards. Post release have pink cpap and 2.4 boards. I’m sure there could be zombie combinations but that is what I have discovered in my fleet and from talk

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

"Wooden" Vase
The biggest issue I had with the S1 even after the motor upgrades is the persistant salmon skin that would materalize on the outer wall of every print when you print at slower speeds, especially vase mode. After a year of troubleshooting with FLSUN including firmware updates of motors with a spcial

Ender 3V2 extruder stepper motor not turning
It's super common practice on cheap machines to stop the plugs vibrating out. Flsun. Anycubic, elegoo, crality. It's worse when you try to replace the heater for the hotend the plugs glued so well it can rip off the plastic of the circuit board. Prusa and Bambu are the only printers that don't go he

Hyping things up yet again...
There’s only a select few YouTubers who will give real opinions. The rest are just advertising. I remember when they were all advertising the Flsun S1 pro, oh man what a hunk of junk that printer was. Looked cool and moved fast, but that’s where the good stopped lol.

Which printer should i buy
I have P1S with AMS and it's great just plug and Play. On the other hand i have Flashforge AD5X multicolor which was half price of P1S and it's plug and Play as well but P1S is 256x256x256 and AD5X is 220x220x220. Great printers but i guess to small for you. I made risky bet and ordered Flsun s1 Pro
