I made it!

[u/adude00]

After so many comments in my old post it's only fair I give you guys an update.

No, it wasn't wet filament. Neither was a clog. Surprisingly, it also wasn't bed adhesion and yes, there were brims. Also, it wasn't a prime tower or some sort of timelapse tower. Its just my part :)

While I'm waiting for the new spools to arrive, I decided to finish up the spool I have doing some science test prints: that 240mm tower that seemed to fail first.

I tried enabling Z Hop (thanks u/FreeThotz !) and slowing the print down (thanks u/Proton_Energy_Pill !) and while they appeared to help a bit, it wasn't enough. I'd get some more good layers out of it, not nearly enough.

Like many have said, the hape was too wobbly: this comment by u/DocJeef had some interesting math in it that made me realize that making the "leg" part of those "L" a bit longer would probably add more than enough stability to print it successfully without changing any settings.

And that was it.

To complete the post I am adding a video of two (different) complete timelapses and a bonus video that shows exactly what was happening in high definition.

Cheers and thanks!

I'm very glad we could help.

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

• What printer are you using?

• What material are you using?

• What speed are you printing at?

• What software are you using to slice the print and control the printer?

• When did the problem start/has it ever worked correctly?

• Does anything cause the behavior to change?

• If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

If you are new to reddit, please read the guidelines on reddiquette, self promotion, and spam.

Also please post a resolution to your problem when you find one so that we know how to help others with your problem!

For such big tower I'd paint organic supports around at one or two levels above the bed. It should protect from excess wobble when tower gets high.

I've printed 10x240mm bar that way at full speed.

Of course it wastes some of the filament, but at least I'm sure that nothing would break off.

I’ll definitely try that out. I just had a print fail, a tower with a smaller base I tested failed :/

Now I’m printing the two bigger parts then I’ll try organic support in the one that keeps failing

[u/pietryna123 → u/adude00]

And I set 2 walled organic support limit to 1mm so effectively whole support is two walled.

Also helps a lot with support strength itself

Good on you for following up with the solution

Slower speed and supports are always the first thing to try.
