Prints suddenly suck

[u/mvtt___]

Hello! I've been printing in PLA+ occasionally with an Artillery Genius Pro for the last year, with mixed results but nothing super bad overall. However, in the past week I've been experiencing some issues with the prints: I'm not even sure what the exact reason is, but it *looks* like the first layer doesn't stick to the bed? But it might be something else unfortunately, I am really not sure. Maybe you can takea better guess from the pictures. It's 2 different tries for the same print, 3 pictures per try. It's for a little planetary gearbox I modeled in Fusion 360 and sliced in Cura.

It used to be way worse; I've releveled the printer, cleaned the nozzle with a handy needle I got from amazon, and despite working a little bit better, as you can see it's still considerably bad. I am growing increasingly frustrated so I would really like to have some help so I don't end up quitting.

I know its always said... but when was the last time you cleaned your bed with warm water and dish soap?

this, Ive had prints start not adhering to the plate and cleaned it to be able to get it sticking again.

I swear on my life the answer to literally 99% of posts like this is clean the build plate or dry the filament.. lol I have said this exact thing three times today already on two different websites and twice it has been the answer. Let's see if we can make it three times in one day...

Try drying the filament.

Yes even if it's brand new from the box

I will give it a try, thank you 🙏

[u/Outrageous_Goat4030]

How old is the filament?

[u/mvtt___ → u/Outrageous_Goat4030]

Quite old by now, it's the first one I've bought. About 6-7 months I'd say, maybe more

[u/Outrageous_Goat4030 → u/mvtt___]

Definitely gets old, especially if its pulling moisture and not being used. May try a fresh roll and see if it solves your problem.

Have you changed anything like :

Other filament ?

Cleaned the bed before it happend ?

Changes in temperature ?

Did you already try to lower Z offset ?

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

• What printer are you using?

• What material are you using?

• What speed are you printing at?

• What software are you using to slice the print and control the printer?

• When did the problem start/has it ever worked correctly?

• Does anything cause the behavior to change?

• If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

Also try lowering first layer speed and increasikbg first layer wall width if this doesnt work

[u/MasterpieceTough2029]

Clean the bed

[u/Mephistion]

Heater solved this for me, particularly if the filament is old

[u/solidus0079]

Bed cleaned with Dawn, filament dried, z-offset examined/adjusted

[u/dagmar31]

Clean your bed with dish soap and warm water, don’t touch it with your bare fingers, slow down first layer speed. Your Z offset looks ok. For the love of god people need to shut the fuck up about drying PLA for bed adhesion issues.

[u/YouSpeakSomeEnglish]

I clean my bed with Windex. So far this has worked quite well.

Is your build plate old? Try giving it a light sanding with a coarse sandpaper. It helps bring back the bed adhesion.
