Love my new printer!
But I get bubbles on the 1st Layer. Not sure why or whats happening. Its not elephants foot. Only happens 1st mm (approx) then prints fine.
PRINTER: Ender 3 Max|
Filament: White PLA 200/60 Stock Everything Settings
Looks to me extruder tip is pushing back through material. IDK.
Are you sure not printing that heat tower from 240 bottom to 180 degrees on top?
What is the use of an heat tower when printing everything the same 200.
I did print the proper temps.
Whats happening is this:
The Nozzle is just bouncing over the print. Its like the Z axis isnt moving at all until about 1mm...Then it prints beautifully.

Did you check connection between Z stepper and lead screw. Maybe the locking screw came loose?
Everything feels tight I dont feel any play in the coupler or the lead screw.
I did find this article seems to be the exact same problem.

Not sure the fix
Try 215º and 60º for a print. 220º first layer. I don't see a lot of use for heat towers. Once you find what works, don't mess with it.
PLA is like warm honey at 240º.
@coolhanmatt Did you ever get this fixed? I have had the same problem with two ender 3 max's. The first one I sent back because I thought there was something wrong with it. I can kind of fix the problem if I tighten the lead screw side of the gantry slightly over tightened and the other side i have to keep looser then it should be. But I get a terrible elephants foot. I think it needs a dual z axis. I see that one side of the gantry has a delay in following the other side when abl is running. I think this is cusing the nozzle to be to close on the lead screw side. I guess loosening the non lead screw side helps it follow better but dosen't solve it fully.
@frankt2012 I think he fixed it. Here is the answer for your reference> https://3dprinting.stackexchange.com/questions/8022/first-3-mm-prints-poorly-then-fine-after-that
@kevin Ok I will try that. I thought I did that though and it got worse. But I will give it a go again. Thank you.
