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

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

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

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

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

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.
