Underextrusion Sovol SV04?
My 3D printer (a Sovol SV04) is suffering from underextrusion. The strange thing is: The first print worked perfectly, but then it stopped working. I've replaced and cleaned the nozzle several times, swapped the heatbreak with PTFE tubing for a titanium heatbreak and then for a bi-metal heatbreak, adjusted the motor driver settings on the motherboard several times, adjusted the E-Steps with Pronterface, tried all temperatures and several different printing materials, adjusted the idler 100 times, and tried all slicers from Cura to Prusa to the Sovol slicer, but the problem doesn't go away.
The SV04 is a dual extruder with 2 print heads, both heads have the same behavior.
I have already worked on two 3D printers and I know a bit about them, but I am slowly reaching my limits with this printer.
I am grateful for any advice.

Isn't that the same printheads as the other Sovol printers?
I own two sovol and have had such a problem once. The cause was a loose grub screw in the sprocket of the extruder. As a result, the filament always slipped through somewhat. But this is unlikely at the same time for both.
Also, you need to turn left when you press the screw to increase the pressure. On the right, the pressure is reduced. But I think you know when you've been working with other printers.
Have you ever tried Sovol Support? They answer quite quickly.
So, I wouldn't set the retrackt higher than 3-5.
The tension of the filament may also be too high. Do you use the sensor? Some filaments are thus very strongly braked. Especially those with additives such as wood, carbon and metal dust.
If you can solve it, please write it in here. The Sovol SV04 will be my next. :
Not the one who has a serial error.
Update:
Have written a minigcode itself, it should be promoted 10 cm, but there were only 2. Apparently, the error is software-related and occurs only on the SD card.
Contacted Sovol Support.
Update: Got the software on the latest version on the Sovol Hompage gave updated, just print a test cube dual and everything looks good. The replayed software probably had a hit, apparently a single case after I no longer find it on the Internet.
Hi, what version did you have on it before? And then played? If or did you have this intertwined wave pattern (it gives YouTube video). I am also despairing…. LG Mindbreaker
Great, thanks. Then he stays on the list. I am really excited to print with two colors. I have a Tronxy with dual extruder but I am not satisfied with it.
I had the same problem with my filament sensors taken out and roller holder(sought the one from the ender 5) printed with ball bearing with my other printer, since it went. The Sv04 are a little bit zig-zag, which I've been seeing several times. But if he prints the quality is great and that with the two print heads is awesome.
Hello, I have sv04 for a few weeks. A few days ago, I noticed that I actually mainly print vases and now went over to print them not only on my sidewinder, but also on the sv04 that, according to the Internet, he causes an intertwined waved pattern, quite in the beginning I also had pure underextrusion problems with sunlu PLA plus ROT, due filament sensors with nem bits, and then the screw went on idler. As mentioned, however, I noticed this pattern. Looks almost like woodmask! Quite a pulsating repeating under/over extrusion. It also adapts to the change in flow. Not only in vases mode, I would have to see in retrospect. But since I've been running 0.6 it's more noticeable. Both extruders have the same picture… Already so much read….is probably a dual Gear extruder problem…but these are underlying single gear extruders….also straight gears and not with a guide groove as often shown in the search. So can't really explain it to me. Slicer does not make any difference…temperature up to 250 degrees at PLA plus also not… Heatbreak is bimetal upgrade firmware is 1.10 so current… PID Tuning made…no change…but I want to sell the products in the future. This is not really the case…. would be happy about any help/dip… I'm just about to disassemble the extruder… someone knows if the parts from the side winder are sprockets, etc. Pass? Last state, I guess either still PID problem or actually a mechanical unbalance…but at both exactly the same?! Very mysterious….
Thank you
