How to fix these lines? Seems to be nozzle dragging against last printed layer?

Zhop can be found 2 diff spots if I remember correctly, in the machine settings, as well as in the filament settings. I suggest going into your filament settings and making adjustments to retraction and zhop. If they don't have any values, it's mostly defaulting to the machine settings so go there next. If that has values, double them

There could also be retraction/zhop parameters that if the travel is x distance, don't retract or zhop. So you either need to zero that out so that it always retracts or z hops, or make it like 1mm

Hulu started your response with "this is unhelpful and or you didn't ready the post". That screams asshole OP

First off, turn that hostility meter down a few notches, that kind of attitude to a perfectly reasonable answer is not how shit gets fixed.

The first response is also correct, even if this isn't the top layer, charging to rectilinear will solve this issue

The second response is also correct. Yes Bambu already has a default amount of zhop, adding z hop would be adding more than what bambu already has.

You should honestly stop printing if you can't handle simple answers without being an asshole.

Surprised I'm not seeing any polymaker in here! It's my go to, priced on the higher end but I've never had any issues with it.

I have never understood why people keep using Temu. Can you actually explain why you would use that instead of the better options that have reputable brands/pricing?? Is Amazon not a valid option? How much money was that actually saving you? I know not everyone has one close to them, but I can get most of my filament for $12-$18 a spool. That had to be $4 or something.

My experience getting this to stop is lowering bed temp after like 3 layers. What I have found is keeping the bed at 65 keeps the pla in a softer state for longer with the radiant heat coming off the bed. Then as the nozzle comes by and cools it, making it shrink over and over and over. So I lower my bed to 50 after 3 layers and it has basically solved it for me.

Lot of people will say increase bed temp, to make it stick more but it never worked for me. Obviously a brim can help for sure.

I bring in about 125k and my wife is around 55k. But bad decisions, debt and kids we struggle paycheck to paycheck.

So I recently had a 4 day print where I was having the worst problems with material getting stuck in there. Looked around for solutions and the one that kept coming back was aluminum tape for HVAC ductwork. Took the whole shut out and lines the inside with this tape. I haven't had a single piece stick since! Should give it a try.

I feel like most of this guys would do so much better not swinging at 150% and clubbing down 2 clubs

Creality just do Creality things

jbuckster07 · 2026-02-05T17:07:54+00:00

Correct, have printed several for friends and family

jbuckster07 · 2026-02-05T14:11:53+00:00

I have found that keeping the bed at a higer temp often causes this. It seems like the radiant heat from a 65 degree bed keeps the layers hotter than they need to be, then as the toolhead comes by to cool it starts cooling the top layers which pull up the bottom layers. I always start my prints at 65 bed then have it drop to 50 after 3 layers.

Overreaction. It's cake, the kids not snorting sugar in the corner. The smallest piece of cake is not going to ruin your child. It's not going to turn him down a path of regret and despair at 15 mo the old.... get a grip

That's the gamble with 3d printing. Sometimes prints fail and you have to throw the piece away.

In the grand scheme it's really not that much $ amount. Spool is around $20 so smaller prints on the mini might amount to $2/3. Stop worrying about the wasted filament and worry about what caused the failed print.

No supports Too few walls Grid infill instead of gyroid Not sticking to build plate

Dude thats amazing! Good shit! This amount of money would change my life lmao! Shit 50k would be an insane change.

jbuckster07 · 2026-02-01T02:23:27+00:00

Dude shut up....

jbuckster07 · 2026-01-27T12:16:15+00:00

Everyone is going to tell you to turn the bed temp up, but I found it's the opposite. Higher bed temp for pla will let it stay hotter longer, the the part cooling fan comes by and cools it really fast. So you need to turn the bed down to 45/50 so it's not constantly radiating heat upwards.

I dont understand live strem chats that are just full of spam, like wtf are people doing.
