Has anyone else purchased this heating block kit?

It comes with a package of thermal grease but no information whatsoever on where, how, or when to apply it. I've checked their tutorial videos, chatted with their ai support, and talked with a human customer support person and have not gotten any applicable information on how to apply it or if I even need to apply it.

Normally, I would just install the kit and ignore the grease. That's actually what I did two months ago when I originally bought the kit. After that kit was destroyed by melted filament, Amazon support had me order the kit again. So now to potentially avoid the same issue, I'm going out of my way to find as much information as I can about this phantom thermal grease.

Any thoughts?

(fixed! It was a screw for the fan!) I found this screw (13.5mm Philips style) rattling around my print I did yesterday. I can't seem to find where it came from yet, but I also haven't had the chance to flip it over and check everything up close.

Thoughts on where this came from?? I can only assume somewhere on the hotend or the X or Z axis tracks, but I didn't see an obvious spot.

I'm still very new to 3d printing, long time reader - first time caller.

After changing my nozzle and doing a cube and temp tower test, I thought I was ready for a ~9 hour print.

Is this *just* wet filament?

The obvious break in the side of the ramp happened when I paused then unpaused the print. I did it a second time and it didn't make such a major mistake. Any ideas on why that happened?

I also had some PLA leak out into the silicone cover on the hotend/nozzle. I was able to clean it, but I assume my clumsy hands messed up installing the new nozzle.

0.4 nozzle at 220

Wall loops 2

No supports (maker world page suggested no supports were needed)

Please let me know if more setting info is needed!

Thanks, all!

Good day all, quite new to 3D Printing and I changed my first bit of hardware yesterday. I replaced the stock 0.2 nozzle for a 0.4, and then after a failed 9 hour print (by far the longest I've attempted) I saw that my silicone cover to the hot end had PLA bleeding out of it.

... I'm going to go out on a limb and say I probably made a mistake when changing the nozzle.

I had already ordered a new ceramic hotend, so I'm not too worried, but to avoid this in the future, what could I have done differently to prevent the mess?

Thanks!

(The nozzle and hotend weren't too messy. I was able to mostly clean it up with just a wire brush. The silicone should be easy enough to clean as well, I assume.)
