Default 3D Printing help

UPDATE!

After leaving the filament in the dehydrator for about 5hrs, I can tell my prints are stronger and not brittle anymore. It is under extruding, so Iím going to bump up the flow.

Please let me know if my pictures are too small/big.

Hmm... I print faster on my Ender 3. Looks almost like the nozzle height is still too high, not getting enough squish. What slicer are you using? Did you try upping the hotend temp?

Ok, next print Iíll drop the nozzle height.

Iím using Cura, and no I havenít changed the hot end temp. Iíll do that too along with nozzle height.

Sorry if this is a stupid question, but how do I lower the nozzle height? The stopper is all the way down.

You will need to re-level your bed to raise the height of the bed.

Been following this...just a thought. I’ve been looking at getting an Ender 3 pro and in my research noted that there are some very detailed YouTube tutorials that walk you through assembly, setup, and first prints. Not sure if you’ve done that but seems like it would be so much easier than getting answers one question at a time in a forum that isn’t necessarily dedicated to printing or that model. Maybe “disassemble” and start over from step 1 but follow one of the tutorials? I know that is what I plan on doing. Someone else already figured all of this out/did the trial and error.

When I assembled it, I followed the video with by JustVlad.

I have been watching a few videos, about to watch some more.

I have been thinking about disassembling and reassembling, but I feel like doing so wonít help, I think itís somewhere I messed up the settings.

Here are some of my basic settings using Cura standard quality .2mm
Print Temp = 215*
Build Plate = 60*
Flow = 100
Speed 80 mm/s
Retraction Distance = 5mm
Retraction Speed 45 mm/s

Under "shell" check your bottom thickness. Mine is set @ 0.8mm. In your second pic above, where you can see light through it, it looks like it is only printing a single bottom layer. Not saying these settings are perfect or, that they will work for you but, they work on my printer. Just something to compare to.

Thank you!

I will continue messing with it tomorrow. I canít print at anything above 45mm/s, or else it looks like garbage. But whatís weird is the first few prints I did before having issues, I was doing 65-70mm/s no problem.

It has to be something I did.

You may have a partially clogged nozzle. Try heating the nozzle to like 220 or higher and manually pushing the filament through.

you could also try https://letsprint3d.net/how-to-calib...der-3-5-cr-10/

*ETA did this issue start before or, after you switched to the Capricorn tube? I'm starting to think this may be a clogged nozzle/hot end issue.

It started happening before I got the new Bowden tubing.

I cleaned my nozzle/hot end once, and it came really clean. Iíll check it again.

Remember you can burn PLA if you get it TOO hot.

The advantage with the Capricorn PTFE tube is it that more flexible filaments work better, as there is less chance of the filament to bind. It's also less likely to stick to anything.

I run this test and adjust the height based on if the filament is getting smashed too much (too low) or if the filament is sticking to the hot end and not the bed (too high).

You have seen the prints that come off my Ender 3, and it prints very well. The only thing I can think of is that either the nozzle if goofed up, there is a blockage in the nozzle, your PLA is not uniform and could be going over spec max diameter, your drive gear on the extruder head is slipping, your extruder lever is broken, your extruder spring tension is too low causing the filament to slip, your spool is not feeding easily, or is bound on the spool.

As others have said, your first layer needs to be right or it can cause problems with the print. This is just accomplished to leveling the bed. Also when you assembled the kit you need a good accurate square to get everything aligned properly. Most of the problems I have seen people having is by not getting it assembled accurately.

Lets us know how it goes.

My filament has teeth marks from the drive gear like itís too tight, but itís slipping like itís too loose. Howís this possible?

I've had that happen to me a few times where once it grabs too tight, it squishes the filament and then once the filament squishes it becomes softer and starts to strip. So you end up with filament that won't push and still has teeth marks in it.

obviously I can't guarantee that that's exactly what's happening in your situation but I have had that happen to me more than once.

Ok that makes since.

Should I cut the marked filament off? It goes in the Bowden tube, just tight

I tore apart my hot end and boy was it goofed up big time. Hereís a few pictures.

If you canít tell, the nozzle is caked in filament and so is the inside of the rubber boot. I cleaned it all off and itís printing normal now. Funny how the last thing I decided to check was the problem.

Sorry that the pictures are so small, I canít get them to be bigger. But if you click on it and follow the link, you can see the picture bigger.
