"Printing time" is really "time on this tab"

André — Sat, 18 Apr 2026 11:27:41 +0000

This time is "how long you watch this tab,"

(you need to click the screenshots, this forum does a lousy job.)

switch to any other, like "print history" , and back:

if you open this well into a print, and see printing time <1m ... you know something is wrong.

Problems printing TPU

manhai — Sat, 18 Apr 2026 08:35:00 +0000

Hello

Since around one week, i try print stuff with tpu. Smaller objekts work very well but at larger objects it always messes up.

For this print i use a tpu from ellego.

For this print my parameters are:

Layer height from 0.15, maximum speed 80, maximum flowrate of 4mm3/s, retraction 0, temperature 230c. I also loosen the wheels.

But at previous trys i reduced the speed, flowrrate and increased the temperature.

I have no idea what i can do to solve the problem

Thanks for your help

Prusa supplied filament profile accuracy.

Trying to help a friend with a different filament. Prusa supplies a profile for the filament in their configuration. Prints with it fail. Temperature is much lower than temp tower test. Doesn't stick to the bed. Splits part way through printing.

Spectrum HT 100 PETG is the filament.

How much testing and confirmation of the suggested filament does Prusa actually do, if any?

I'm missing my CoreXY Strut. Where can I get another one?

What's your preferred method of 3D model assembly instructions?

I am working on a new project, and it's going to be the most complex I have done so far.

If/when I post the model I am debating how to post the assembly instructions.

What do you guys prefer when building for the first time? Pictures? PDF's? Videos? Or does it even matter.

I'm not too keen on video... unless it's completely exported from Fusion. I'm not sure but I guess Printables can upload an instruction sheet pdf file?

I've done text, I've done different formats of pictures... I need to lock down a standard going forward, I guess. I don't know the first thing about youtube or whatever, so videos are kinda... eh.
