AI Help

I'd be happy to help troubleshoot the issue with your 3D printer. Can you provide more details about the specific problem you're experiencing?

Why is it happening?

speed changes.... (Possibly)
What else can i do to fix?
increase time for the speed to speed uo and slow down.

Why are my 90 degrees edges bulging?

pressure advance seriously needs tuning for this filament.
tune this by following this guide.

Yes, it's none of those.
99% is pressure advance here:

Please tune it for this red filament
It'll take maybe 30mins at most. 😅

Did you do the pressure advance tuning?
Are you using cura?

Yeah true...
But pressure advance is sortive flowrate...but only for the corners. 😅

If you run through ellis guide... (Especially extrusion multiplier part) in order. 😅

Perfect!
Which feels the smoothest to you when you rub your fingers over it..
It's really important you have the z-offset correct before starting and checked everything else before it mentioned in ellis guide.
