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.

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

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

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

Calibration issue
I’ve had this exact same issue with my first 2 t1s, both required mobo replacement, and my s1 pro. All were not fixable, required replacement. Try contacting FLSUN support, they probably won’t reply as they are out of business (or close to). If no reply file a BBB complaint. How long ago did you buy

Don’t like my Qidi, sell me on an FLsun
My s1 i got before release from flsun still beats the flsun s1 pro I have and when set right and slowed down is super clean especially being open source as well. If it had interchangeable heads for multicolor and a circular camera ring to auto 3d scan it would kill with its built in lidar and full b

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
