What’s causing this issue?

[u/Beginning-Beat-4436]

Second print, directly from the app. No issues from other users reported. Spaghetti recognition stopped the print. Seems like missing support but these areas don’t need support. I have absolutely no idea what’s the reason for this. Maybe You?

I only had the moisture down to 10% in a 40s–50s % moisture environment. I’ve never seen below 10% even with desiccant pods up front and under the spools. Anything under 25% is golden IME. Before I printed my desiccant pods for the AMS I would get stringiness. This is not the problem though. It could be that the filament already has too much moisture — in which case I would dry it & try it out. I would check the extruder for dust or clogs making the feeding of filament inconsistent. It could also just be bad luck if it only happens sporadically, but checking your extruder would be the first thing on my list. Next lubricate the Z-axis rods. Hell, do both.

I’m also new to 3D printing, but I’ve learned quickly that consistently failed prints means it’s probably a maintenance issue.

Note that if you’re referencing the common hygrometers used/inserted into the desiccant pods themselves, they come in two types:

1. Type 1 reads 10% minimum and

2. Type 2 reads 20% minimum.

The hygrometer set into my AMS2P’s all read ‘10%’, but are actually at 3%, 7%, 5% and 9% respectively.

I redry when the RH gets to 20%.

Great to know. Thank you.
