Aight, I recently purchased this. Did everything the instructions has said. Updated firmware with the 400mm extruder g.code that’s required. Tested E Steps, was right on the money. Leveled bed. Did PID auto tune(7 cycles) on both hotend and bed.

Did probably 2 good prints and then I’m under extruding. Did a flow test with a cube to see if I’m going too fast. No, it’s right on the .4mm thickness mark that input on settings. Did anther E-Step calibration, im under. Calibrated it. Ran it again, extruded the right amount. Leveled bed again just in case.

Now, after a few days trying to get this bad boy to behave, I’m at a loss. Did a bed level print, it’s fine. But when I try to do an actual print, it goes well for the first layer, then the nozzle picks up or just pushes the filament that’s already based. Some parts pops up. Which is weird because I get good adhesion on all my prints but now, I’m not able to.

I did the process again. Leveled bed. Print bed level. All good. I just can’t get this puppy to stay still. Or is the jyers firmware that’s interfering with the prints?

I don’t have any pics to show because I’m not able to even print anything that can give any justification of what I’m trying to explain.

With the stock extruder and hotend for the Ender 3 V2, I was running my PLA+ @210 and bed @65.

This this one, I’m running it @220 and bed @65/70.

First initial layers for like the skirt or raft, looks like a pancake so I know it’s good. It just does that. Starts clogging but not really clogging outside the nozzle tip because it just picks up the filament from the bed and gets stuck on the tip. Idk.

Maybe I’ll try to post pictures later on today or tomorrow. I work nights and it’s already about to be 11am. Been at it for a bit now. But if any tips or suggestions, they’re all welcome. And all are appreciated.

Thank you!

First layer prints smooth. And that is what baffles me. Because before, it’s just doesn’t catch due to adhesion. Turn it off and then back on and it prints.

I agree with Max about the heat issue. The inconsistency on small cross section parts is telling. But it also looks like your nozzle is on the high side. You shouldnt be able to see a gap between the skirt lines

I have that nozzle damn near close to the bed. Like 1/16” more and the paper is stuck. So I have pretty close. The Z offset, I still have at 0.00 because it’s that close to the bed. But if heat is the issue which I kinda wondered as well. I will play with the setting when I get home from work tomorrow morning. I’ll try 215 instead of 220.

Or leave it at 210 before switching from stock hotend to NG?

1/16” is a ton when we’re talking about tenth mm

#

.2mm is about 1/128”

Lol. You know what I mean though. Practically one little touch on the knob and it’s grabbing the paper. But I just got home and will try to print something with default settings.

So, took off pikachu off the bed. The ugly support in front of his chin came off rather easily. The bottom of the print looks and feels super smooth.
