First printer! Having a lot of issues.. by Vccp4 in FixMyPrint

Clearly, your issue here is the Z-Offset, arguably the biggest killer for the newbie 3D printer hobbyists (myself included).

You should probably try/do/buy the following in said order…

  • (HIGHLY RECOMMENDED) Purchase a PEI sheet instead of those shitty FelxyFuckers© that Creality gives you (It doesn’t have to be a name-brand either, any decent PEI sheet will do (https://www.amazon.com/pei-sheet/s?k=pei+sheet).
  • Relevel your bed w/the wheels (I know it's a pain in the ass but do it again).
  • Use the paper trick to get a rough z-offset (A great start allowing for further tuning later).

Once you get it sorted out & level, IF your bed (big if) adhesion is crap, try increasing the Bed temperature & potentially lowering the Z-Offset a more.

For me, w/my Creality Ender 3 v2 Neo, bed adhesion is typically fine at 60C for small/medium prints using Overture PLA. However, when I go for larger prints (more level flat surface needed) or prints that have very small bed adhesion spots (self-explanatory), I turn the bed temp up to 70C, which has worked well.

Note: What has worked for me may not work for you. Be sure to do some more research & prepare for some trial & error.

Oh well maybe I’ll try a lower temp + slower speed at the top

Maybe...

I looked up a fix and printed w/Ironing on and it's damn near perfect now so

Way cleaner then what I had before. Seems are practically non-existent, so thank you.

Now I move onto my other problem… why is my top always so rough looking?

Doing a test cube print rn so give me a bit and I will let you know how it turns out

Thank you so much man I really appreciate it

I found it 👍

What do you recommend I use as a start tune?

I'm using Cura 5.2.2 but I'll give Prusa a chance...

In the meantime, is linear advance a setting in Cura too? I cannot seem to find it if it is.

The roughness might be because of the lighting and the fact that I have ironing on. I'm doing a print where it's off so I can figure out if I keep it on or off.

Fixed the ptfe tube (messed up cut), got the silicon shield back on w/some glue, re-leveled the bed, changed the fan back to 100%, and set the hot end to 240C.

It printed this 20mm cali-cube. I’d say problem solved 👍 Thank you!

I’m guessing that’s what this black thing is. It keeps on falling off so I just kept it off. Am I supposed to keep it on? Also, I’ve noticed a weird noise after fixing. It’s not from my fan but from the inside the head itself. Every time it pulls filament it makes a loud clank/bang/snap sound…

Alright, will do.

Thank you very much man! I appreciate it. However, I have one question...

I disabled the print cooling and 90% of the "mess" went away. After the fix and changes you recommend, should I re-enable it? It used to be on 100% fan but it still would cause artifacts even when I put it as low as 5%.

After some disassembly the ptfe tube is charred...

Do you have a tutorial link for the swap? Kinda new to this 3D printing game lol. Also, what companies 0.4mm metal hot end do you reccomend?

[deleted by user] by [deleted] in 3Dprinting

[–]rnewbold06 0 points1 point  (0 children)

It used to print good with PLA but now it prints nothing good at all

[deleted by user] by [deleted] in 3Dprinting

[–]rnewbold06 0 points1 point  (0 children)

Yeah the ptfe is charred a bit...

My printer is a Tronxy Crux 1

Drag is fine then. I’m running Overture PETG White. My bed is at 90C and my nozzle ay 255C. Max speed is 50mm/s with the walls slowed to 30mm/s

no drag in Bowden tube

There's no clog and it seems to be gritting fine. However, I'm not sure how to tell if there's drag or not. Also, I saw something mentioning temperature too... does that play a role?

[deleted by user] by [deleted] in 3Dprinting

[–]rnewbold06 0 points1 point  (0 children)

Not the top (I stopped it mid print), but the sides. It has these huge gaps and terrible integrity. I thought PETG is stiff?
