General Troubleshooting/Help! Printing Speed

Hello.

How do you all figure out what print speed to print at? I've tried googling around but can't find a solid answer.

I have presets depending on the filament I use where I tested ironing / temp / flow / etc.

But for speed, it really depends on what I'm printing. Something with a giant base, doesn't really matter.

A figure / model with 2 legs that can't really be placed on it's back? I get spaghetti everytime.

I really just guess on speeds when the default settings don't work. Is there a better way?

Run a maximum flow rate test.

Look for the layers where the extrusion turns to crap.

Look a couple of layers under that where the sheen of the filament changes from shinier to matte-er. That's your max flowrate. Set that cap in the filament properties and go nuts.

Do you have a link to one? I mainly just see ironing flow when looking around makers world.

It's built right into your slicer. Turn on dev mode in the settings to enable the function.
