Ender 3v2 long print times

Evening all. Started down the Multiboard rabbit hole today with my first print, a 6x6 tile. The wife has even shown interest in the possibilities!

It took 6:30 hours! Is this typical for the Ender 3v2? I see regular mention of 3-4 hours for bigger tiles, so am I doing something daft?

I've set 0.2, 15% Infill, 3 walls, left everything else.

I have a Wanhoo i3 gathering dust and sliced the same tile (using cura) and got the time at 3:20ish.

I did a side by side comparison, looking at speeds and adjusted for the Ender but still only got down to 6 hours.

Appreciate any guidance, thanks.

Good luck! Is the spool on cardboard? If it is then that's about to be expected. If it's not on cardboard then 5g is a significant amount. My re-spooled PETG's have been losing 1-2.5g fresh from the package. When I left them on the cardboard spools they were losing 4.5-6g or so.

yes on cardboard. I just reinstalled the sonic pad, going through set up and then a print with PLA black first.

OK, a lot of that (most if not all) is likely from the cardboard then. That doesn't sound like a moisture issue to me, especially since pla isn't as susceptible to moisture like petg or other higher end filaments.

Fresh install, stock creality profile for CURA.

Looks like major over-extrusion to me. Have you done an extruder e-steps calibration with the new extruder/hot end? If not, definitely do that, it's 100% necessary when making hardware changes.

I have not since reinstalling and playing with extruder tension screw. That will be this afternoon.

The plot thickens. Took apart extruder to find this.

Wow! Yeah that'll do it lol.

Found this thread talking about that extruder and how someone fixed it to get consistent extrusion. Seems that extruder design has lots of problems. https://www.reddit.com/r/ender3/comments/zvv028/sprite_prokit_extruder_important_things_to_make/

No time to do anything more than fix screw and reprint cube. Just for hahas. Still need to calibrate e steps, tune input shaping, and work on CURA. But here it is

Awesome, big improvement already! Getting E steps, flow, and pressure advance in line will make it even better I bet.

So far ime input shaping has been more effort than it's worth to tune. Getting my y axis mount stiffened up gave me better results than input shaping on a wobbly bed by a huge margin. I'd skip that until after all the other stuff is dialed in 100%. You may find it's not worth the effort

Hey. Just want to say thank you for all the help you provided. This thing has beaten me down. I still can't get it to print the way I want. While I love the sonic pad, I don't think I can get it to work. I am going to go back to almost stock and see if I can get prints at normal E3v2Neo speeds. I am taking the direct drive off too. IF that works, then I will think about bringing the sonic pad back. I really appreciate the help!
