Doubt it. You're inside, humidity is probably fairly stable due to the AC (you do have it inside, right?)
Humidity is an issue when the filament has had time to sit and absorb moisture from the air, all plastics do it to some extent. They sell driers, or you can make one which would certainly be in your capabilities. Certain nylons can absorb as much as 50% of their weight in moisture, if I remember properly.

Do you have any filament retraction settings enabled? It usually helps me with stringing.

I've no idea. :lol: I read a couple threads about this printer and it seems support is supposed to be pretty good, so I just shot them a message.
 
Printer Settings > Extruder 1
Look for "retraction" post if it is enabled

Also (and I think gee already said this) all filament is slightly different. I've had to slightly change settings when I start a new roll of filament. It may require some slight dialing in.

That's a good point about filament. It's just odd that it seems to have gotten worse (with the same filament).

PLA is somewhat affected by humidity. It's good to try and keep it dry, either with a spool dryer or by throwing it in the oven for an hour or so before you print. Either way, storing it with dessicant is a good idea too.

I'm pretty unaffected by this because my natural humidity level in New Mexico is less than 10% for much of the year.

I imagine in Florida unless you've got a REALLY good AC and you don't have a humidifier piped in after the evaporator coils, that it would be a bigger deal.

That said, the worst filament for that is nylon, which holds on to water like you hold on to cock.

A filament relatively unaffected by humidity is PETG, if you want to go that route. It'll take dialing in on its own though.

Ummm, how the fuck do I fix this? And how the fuck does this even happen?

Fuck, I see what happened. It looks like the printhead slammed into the bed, scratching it. I seem to recall hearing it make a weird sound before I went to bed. Fuck, what do?

Tell 'em what happened and get another print bed sent to you - https://shop.prusa3d.com/en/contact-us

Did it start happening right away when it first started printing, or did it work from the beginning and then fuck up?

I got most of it off by preheating it and letting it sit there until the shit loosened up enough to pull off. However, there's still some gooey shit around the nozzle.

If you re-heat it, some careful work with a brass brush will probably do the rest of the job. Just be careful with the leads going to the heater and thermistor.

Preheat and wipe it off (carefully) with a paper towel. Popsicle sticks are also good for poking/scraping, split them in half to put a sharp point on them for digging.

Nothing to input beyond what has been stated. Usually doesn't happen until you are much further down the road.

How many successful prints do you have on the machine so far?

Any time I do a big change I usually watch the first two or three layers before ignoring it. It takes me maybe half a dozen prints before I feel comfortable hitting "Print" and walking away.

Gotta be at least 20+ prints so far. No big changes.

That's really strange.
This thing has a bed probe, to tell it where the bed is? If so, I wonder if maybe something wasn't as tight as it should have been? That or some wiring coming loose are the only things I can think of.

Now that I think more about it, its super weird. It NEVER actually printed anything. Not the little goop line it always prints to start out. It just went to a random spot near that, slammed into the bed, and started extruding. Apparently not moving at all.

Remember what it was supposed to print when it did that?
If so, open up the gcode file for that one, compare the first 20 or so lines with a print that went well.

Can usually open them with a Notepad++ type program
