Hi folks, I’ve had my ender 3 v2 for around 2 years and it’s been trouble-free until lately. Recently, I’ve had major issues with the first layer. I found a few worn components, so I got a dual gear extruder and replaced the nozzle, recald the esteps, bed level and z offset. Nothing I do seems to work.
The issue happens on the first layer when it first starts to extrude. The first 5mm or so of extrusion curls up behind the nozzle, then the extrusion sticks to the bed and it continues normally… Until it needs to starts a new extrusion, then the same thing happens…the curl.
I have to think it’s something with temperature, but I haven’t changed anything about the filament since these issues started.
Looking for any advice. Thanks!
ok ok, I’ll put the old bed on after I wash it real good…I do this periodically but maybe I was eating chips or something.
Gahhhh same thing… I’m on day 4 of this bs. I’m gonna throw my printer out a window
Glass is really hard to stick to. You’ve gotta get the z axis just right. I know it was working before but it happens. Don’t give up but definitely take a break if you need. Highly recommend putting down some purple gluestick, it helps a ton. It isn’t your fault if you’ve cleaned the bed, it’s gonna take some patience. Maybe look into getting a PEI sheet if you don’t have one? There happens to be a limited time deal on one your size (235x235mm, ender 3 v2 and aquila are the same) on amazon for $10: https://a.co/d/emfbtnc
Not a referral link or anything, but I really recommend one. They’re usually around $15-20. I haven’t touched my glass bed since I got one. Other than that honestly dude just go back when you’ve got more patience and download a bed leveling test print, and keep tweaking.
A little aqua net hairspray will do the trick too.
It looks like your Z offset is too high. I think you calculated in the wrong direction. Your Z offset should be so that if you go to Z 0 then your nozzle would just barely hit the bed.
Don’t give up!
