#PrintClinic I was going to try to figure this out by myself, but Makerworld made the "Print Clinic," so here is my small problem. Hey guys, my A series printer is having some trouble with bed adhesion. Before you say "is it clean?" Yes, it is clean; it was washed with soap and water, and even still, the print did not stick to the bed. The only way to ensure, right now, that a print will not fail 60% of the time is by using brims and glue. Here are some of my ideas about the problem/what I could do. 1. My build plate is 1.5 years old, has about 2000 hours on it, and is Textured PEI. I had a newer build plate, but it broke, so I need to buy a new one. Do you think the PEI surface is old and has lost some of its effectiveness? 2. My printer may need its belts tightened; it has been 6 months, so doing so couldn't hurt. 3. Is there a way to manually calibrate Z-hop? 4. Before I do anything, I should probably auto-calibrate and see if there is a difference. Please consider this, and if you have some new ideas about what I could do, please comment! Thanks! ;)

@berri3D : Hi there! Thank you for the detailed information as it helps us help you :) 1. Build plates are consumable. After 2000 hours of use, it may very well have worn out, especially if you've been printing with PETG. PETG is particularly sticky and will wear plates much quicker. 2. It never hurts to do regular maintenance! That said, loose belts would be giving you vertical wall artifact issues. Instead, I would inspect other things in particular, the screws behind the nozzle are a known issue in that they can become loose and require tightening. A slightly wobbly nozzle will absolutely throw off levelling and cause poor bed adhesion. https://www.youtube.com/watch?v=k2BYvY72XSM. Likewise, a dirty or worn out nozzle can be a culprit, too. 3. While yes, there are ways, it's using gcode to fix a hardware problem. I always look for the root cause instead of bandaid fixes. I have more to say, but character limit 😜

@MakerWorld : Thanks for dropping such expert advice and helping out fellow makers! We're lucky to have you in the community!

@nibotnibot : @berri3D : yeah, I noticed the under extrusion too. I’ve been having that for a while, but it’s because I 3-D printed a mod for my printer while I wait to get a replacement part. The part, I broke was a AMS hub and a three printed one has way too much friction.

@Stevebaugh21 : I had the same problem with adhesion before I bought by bamboo P2S. I would put a layer of glue down It doesn't have to be expensive, Amazon's choice stick glue works fine then right before the print started I would lightly missed mega hold X5 hairspray from Walmart to make the glue really tacky after that I never had another adhesion problem. I do think you should change your build plate first. I just bought one of the low heat build plates off Amazon on sale for $12.99 and I love it. It's blue in color if you're interested. Good luck I hope something works.

@nibotnibot : OK, thanks I think I have it figured out now though.

@waylaidwanderer : Welcome to the Print Clinic! We can certainly help you diagnose this bed adhesion issue, but we need a few more symptoms first. Could you let us know what type of filament you are printing with and what your bed temperature is set to? If you have a photo of a failed first layer, that would also be super helpful!

@ImPotatoChetoo : @nibotnibot : quite a lot of under extrusion but I had that problem for some time on mine and I'm not sure but the combination of things I did resulted. So I washed my plate very well but that time I used the green part of the sponge to wash it and I really scrubbed lightly the plate to remove a thin layer of PEI (because I have used isopropyl alcohol without knowing it hurts a lot the PEI layer) and I washed very but very well the soap because it too prevents the adhesion, and magically it worked like new !

@nibotnibot : Here’s another photo.

@njkenn20 : try glue on the build plate also washing plates with a water soap and rubbing alcohol. wash it with a micro fiber cloth and that mixture. Also if its pla bed temp does not matter as much.

@njkenn20 : @DunderMifflin : use really hot water when washing it

@DunderMifflin : the type of soap can matter, mine would only stick again after using dawn power wash and the hottest water

@chhc2015 : i just started using ams with my a1 the toolhead has been clicking is that normal? pls help

@nibotnibot : Not really. If filiment is not comeing out, you probably got a nozzle clog.

@Cassiemomto3elz : my build plate is over 2 years old and still works perfectly.

@Cassiemomto3elz : I also Want to add there's over 4000 print hours on it

@the3dbros67 : yea I think it is the old build plate

@user_3745176624 : build plate

@user_1247297404 : i think you should show a picture of the fail

@nibotnibot : There are a couple of photos in the other comments. ;)

@TheLittleA1 : Hey! I was having similar issues! I found that if you tighten the set of screws behint the hotend it raises the nozzle, and this might be the issue because the nozzle could be plowing through the first layer if fillament.

@TheLittleA1 : @nibotnibot : Alright thank you for responding! 😊

@nibotnibot : Thanks for the suggestion! I think I tightened those screws a month ago though so it should be good.
