Couldnt add the photo to my last post but this is what’s happening when i try to print lately. PLA 200/80 is what i tried this time. Same results as before. Really needing some help here
Just bought a new printer that’s set up for PLA from the factory. Total nightmare. Going back to ABS.
Blue tape works wonders.
Bless you! (Hands you a tissue)
I read your last post. 
Have you tried blue tape?
I just made a cold bed printer (with glue stick) for PLA and so far only the first print (cube) came out decent. After that I’ve run into adhesion problems and it’s been a pain.
am I the only one or is there a glados? 
I use PLA only (well, did do some PET too), but mainly just PLA. I would clean your bed completely off and start over. 80C is a bit hot for PLA. I run my bed at 55C which is the glass transition temp. Too hot will not let it stick either…
Try 210 and 60c bed with blue tape. That much glue just makes for a mess. A thin layer would work way better.
If the z height is off, it won’t stick. Too low and it blobs up, too high and it drags around. Same if your extrusion rate is off by a large amount.
Your hot end needs cleaned out, it isn’t retracting right, and it is sticking to the end of the nozzle.
@Kevin_Rutan I think you may be right just because of the way it looks when it’s trying to come out of the exturder. Problem is, I’ve never done that before. How do I go about cleaning it?
@Nate_Bee i got a cleaning filiment, and i just ran it through for a while. I am sure there are other ways. Also, i used rubbing alcohol and paper towels to clean the hot end.
@Kevin_Rutan ok I’ll give both a try. Thanks
I print pla on cold glass with hairspray. Works very well if i add a brim.
Looking at your bed surface I’d say your nozzle is dragging through all that glue. The glue is probably contaminating the material exiting the nozzle.
I would clean the glass thoroughly and, seriously, try printing on clean glass (set your Z height accurately for this).
If that doesn’t work for you, wipe a thin layer of glue onto the glass surface. It needs to be barely perceptible not piled-on like you have right now.
- Clean your bed (like your mother told you)
- apply a thin layer of glue stick while the bed is warm (50C) or ABS juice while the bed is cold
- don’t raise your bed beyond 60C for PLA, 50C will probably be fine
- ensure your nozzle is not too high off the bed
- print your first layer nice and slow
- watch your printer while you are printing the first layer or two, you might get some clues as to where the problem is occurring
I’d say it could be a combination of several of the answers given. Your bed is certainly a mess, at the very least the end shouldn’t be tracking through it like that as you’ll have some kind of build up. The tracks also suggest it may be too low.
Yep, I’d go with properly cleaning the bed, hairspray or tape, heated somewhere between 50 & 60C.
As @Dani_Epstein said, watch the very first layer, if it’s a sticking problem you’ll see that immediately.
@Dani_Epstein lol. You are absolutely right. So I cleaned the bed, but still got the same results, so I have to also agree with what @Neil_Darlow said about the nozzle. I saw some vids about soaking it in Acetone, putting some heat to it and then cleaning it with a thin enough wire. Anyone know of any other alternatives that may work as well?
Try a cold pull. Acetone won’t dissolve PLA.
+1 for cold pull, that works most of the time. Could be complemented with jabbing something thin into the nozzle while warm. A thin steel guitar string is what i use. They’re pretty cheap even if you don’t actually play guitar and come in lots of sizes. Also, is that photo tricking my eye or is the extruder not straight? If not, that definetly needs fixing. It needs to be perpendicular to the bed and solidly mounted. Watch it during a print, if it moves around at all relative to the mount point, that is a problem.
