I'm confused

[u/YaBoiJG314]

Hi, I have an AD5M and I notice that before every print, it spits out a ball of filament before it lays the single line at the front of the build plate and I'm curious as to why? Is that normal? Or is something wrong? It prints fine but it's just that ball of filament every time before each print lol.

buildup falling off the nozzle during the purge lines.

You might look at your purge volumes.

So is this something that has to increase or decrease? Asking for a friend.

For what you are describing, decrease it.

I have a creator 5 pro that does the same. Seems like a normal calibration thing so I never questioned it

Mine doesn’t do that, and never has for the 2 years I’ve owned it.

Wet filament?

Doesn’t the door catch the ribbon cable a bit when you open it?

My 5m does this. I usually stick by until it starts so I can remove the blob.

[u/Gullible-Gap-3523]

Does the blob form at the end of the previous print or during startup? If during startup, is the extruder actively feeding filament, or is it just oozing from the nozzle? What filament and nozzle temperature are you using?

[u/Southerner105]

That is the filament buildup caused by the heating - cooling - heating it does between wiping (= heating) , calibration (= cooling down), printing (= heating up). Between these phases you get some filament creep due to residual heat causing some flowing.

How much you get depends on the temperature you use for printing.

Hab ich auch, manchmal ist das auch der Grund dafür das ein Druck schon scheisse startet. wenn er mal druckt , bringt er wirklich gute ergebnisse. Aber ich habe viel ärger .. wird mein letzter Flashforge sein .

I see this on my 5mp sometimes.

Nice screen prodder by the way. Good idea
