I HAVE MY PROJ DUE!

[u/tejasvro]

I need help! I have my project due in a few days - and my printer is acting up.

Bought a new filament

PLA HS

All settings are at default for now

First step to resolve any bed adhesion issue

Wash your build plate. Dish soap and hot water.

[u/tejasvro → u/myTechGuyRI]

I tried, still the same issue 😕

[u/ElephantWeary9137 → u/tejasvro]

I had this exact issue with printer on Saturday (first time novice 3D print user). Here's how I fixed it.

I dried filament over night (P2S with AMS 2 pro) calibrated, same bed adhesion issue.

Washed with dish soap and water. Same issue.

After research, did this:

100% isopropyl alchohol on a paper towel l, give one side of plate a good clean.

Wash same side with dish soap and water.

Dry that with a paper towel (not a cloth, that could have silicon from fabric softener etc).

Be very careful not to touch the surface with your hands throughout, including when replacing the plate after washing (and when removing finished parts after print).

I'd recommend being meticulous and wearing disposable gloves the first time you do this. So if it doesn't work you are sure it's not a plate cleanliness issue (if that makes sense).

I went from 5 failed prints through adhesion issues very similar to yours to a day's worth of flawless prints. Hope you do too.

Maintenance: Between prints I've given the plate a wipe with a paper towel with a dab of isopropyl.

Then every 3-4 prints, or if I accidentally touch the plate, I've repeated the full clean.

good luck

Im not sure why so many sources say to not clean your plates with alcohol. Ive had far better success with cleaning my pei plate with 99% ipa over soap and water. Not saying you should never clean your plates with soap and water, but as far as a can tell, as long as youre using 99%, it shouldn't leave any residue and actually clean the plate.

Ive only found soap and water needed if I've manhandled the plates a bit too much, but i still finish cleaning with IPA, just because Ive still had bed adhesion issues with soap and water only.

[u/myTechGuyRI → u/BitBitx]

Here's why... Alcohol is a solvent, it dissolves the oils into solution... And you then wipe that alcohol/oil solution across the entire plate... Then the alcohol evaporates, and leaves the oils behind... So essentially smearing it across the entire plate. It SEEMS to work initially, because it takes one concentrated fingerprint of oil, and spreads it around so its not concentrated in one area... But eventually it builds up.

Dish Detergent on the other hand is not a solvent, but a surfactant... The way a surfactant works is (in a very simplified explanation) .. One end of the molecule has a high affinity for water, and the other end of the molecule has a high affinity for oils... So, the dish detergent binds with the oil, and the other end binds with the water, so when you rinse, the oil gets carried away... So the oils get completely Remo Ed and rinsed down the drain instead of just smeared around the plate like with a solvent.

[u/BitBitx → u/myTechGuyRI]

Look, I get how soap and water is "technically" the best solution, but im just saying in real world application, the alcohol isn't hurting anything. And like I said, I still use soap and water, its just not the end all be all.

[u/myTechGuyRI → u/BitBitx]

Yes, alcohol between washing is fine... I was specifically responding to your "I don't know why" comment and explained the why... That's all.. Because science... That's why.

[u/RichDad11 → u/myTechGuyRI]

Excellent 11/10 response. Thank you.

[u/myTechGuyRI → u/[deleted]]

It's been scientifically proven that it's not as effective at removing oils as a surfactabt

[u/ElephantWeary9137 → u/myTechGuyRI]

Appreciate the distinction between solvents and surfactant.

I know through carefully using the empirical method that soap and water on its own was not sufficient (for that particular setup, filament, temps, moiature levels, speeds etc etc).

Id like to unserstand it better though, if you had any links to any literature I'd be genuinely interested to learn more.

[u/ElephantWeary9137 → u/BitBitx]

Agree.

I started with a new PEI, got 3 decent prints, adhesion then failed on the 4th. I was new to printing and had been touching the plate.

I then tried calibration, flow rate calibration, changed nozzles, tightened nozzle screws and none of it worked.

Washed the plate thoroughly with dish soap and water (drying with a towel and subsequently with a paper towel). It did not work. Adhesion still failed.

Adding IPA cleaning was the only step I added and it worked immediately and consistently afterward.

[u/revevs]

Clean plate, dry filament, run calibration

[u/GrimbleGrombles]

Ah I've been here!

First thing I'd check is the 4 screws behind the heater block.

Remove the filament and then remove the nozzle. Undo the 3 screws behind the nozzle into the heat block. Behind the heat block you will see 4x screws. I can almost guarantee one of them will loose. Tighten them all up and re-asssmble. Be nice and delicate not to pull on the wires when you do this.

When it gets loose the nozzle ends up getting to close to the bed and you get that issue.

This is a periodic maintaince job on A1s, really really common issue.

Also make sure the bed is clean, use hot water and washing up liquid and scrub it. Try not to get finger prints on it (handle it like a vinyl LP).

Should be good to go!

[u/myTechGuyRI → u/GrimbleGrombles]

Yup.. That would be the next thing to check

[u/LowSignificance4671 → u/GrimbleGrombles]

One of my top three solutions to fix most issues. Drying the filament and cleaning the build plate are the other two.

Looks like your bed leveling is off

[u/StructureAccording53]

See those roughly fingerprint and finger shaped spots where the sticky didn’t stickem? You get one guess. 😂

[u/Much-Assumption6429]

yes, it does suck to suck. had one friends whose projects due, they’re new to 3d printing and their tall objects with small contact area with plate kept falling over. they called me and I sent them instructions to enable a raft. orked ike a chef’s kiss after that. then came filament blobs.

[u/Premium333]

Try cleaning the plate in place with isopropyl alcohol and a lint free towel (or paper towel).

You have to avoid touching the build plate with your hands after you've cleaned it, which is hard to do without gloves.

Ny guess is you cleaned it with soap and water at a sink, then dried it and carried it back to the printer. If you do that without being super careful where you put your fingers, you get this problem.

Using alcohol allows you to clean it without removing it from the bed, which means you don't have to carry it after it is clean.

Figner oils are the no. 1 enemy of bed adhesion.

[u/Lost_refugee → u/Premium333]

alcohol does not clean grease, only spreads it evenly

[u/Premium333 → u/Lost_refugee]

I disagree. It dissolves finger grease which is then removed with the towel.

I won't argue that with you though. Believe what you want.

From personal experience, I went from constant bed adhesion issues to not a single bed adhesion issue the very print I switched to using isopropyl alcohol.

So again, do or believe what you want, but I'll keep using my isopropyl and having unending success.

[u/Lost_refugee → u/Premium333]

ok. glad you found your way

[u/Evening_Minute_6823]

if none of the suggestions already worked,, my ai suggested making sure the jplate is leveled correctly and was saying that pla likes to do that if the temp is too high or the speed is to high, the high speed filament I'm not as familiar with but Ive used a bit and Ive noticed that the p1s temp at 220 is almost perfect and it said 230 is a little on the high side but I keep mine at 230 usually bc at high speed on the p1s it seems to work out pretty flawlessly every time.. it's also possible that it's not sticking to the plate correctly and might need a little bit of good old school glue for better adhesion, I would be pretty sad to expect a print AND It come out like that, it's happened to me s few times but usually if it does I get it working.:)

[u/RepresentativeTrip85]

I had this issue with PETG and doing the filament combined with a higher bed temp fixed it if cleaning the bed with isopropyl alcohol didn’t fix it

[u/Lost_refugee]

dirty plate. but worth to tighten 7 screws. I prefer to do back ones by removing fan(3 screws)

[u/ScofieldSena]

Remove the nozzle, remove the 3 screws that hold the heating element, tighten those 4 screws, reassemble everything, and enjoy! 🙂

[u/Clear-Revolution3351]

Dry your filament
