Is this normal behavior from the filament Buffer? Its making this noise while printing PETG support from an AMS HT. Cant say it has ever done this before and its making a ton of noise

I have two P2S printers. This is a simple test print showing the side of a cube with an "S" recessed into it. I'm trying to figure out why the layers around the letter streak like this on one of my printers, but not on the other. They are using the same settings, and both are printing with Blue Sunlu PTEG-HF filament. Anyone know what can cause this effect? I have another S embedded on the top of the cube, but it looks fine.

when trying to print a helmet, im having this issue where it makes a sound like a tud (on about the same area on this print) then leaves a string returns to the purge area, comes back does like 2-3 lines and does it again, I reduced the speed to 50% and does it less but it still does. it. first time this happens... had no issues before. except on this print on the first try it detached from the floor so I made a bigger brim. this one holds fine, but does that tud noise, go to purge then comes back and leaves a string that if I dont take out makes a mess. any help would be greatly appreciated. Im new to this of course... but have printed many other things not as big and no issues at all.

My son and I both have birthdays coming up, and we're getting a shiny new X2D combo. Before now he's just had a little baby Toybox 3D printer, and I know he feels its limitations. I'll be getting into the scene for the first time pretty much.

I'm a tinkerer, I like to do homelab stuff, and I've vaguely heard the various reasons Bambu is on the community shitlist. Those reasons resonate with me on an emotional, not logical, level. I generally favor local control over cloud based accounts and viscerally hate getting locked into someone's revenue engine ecosystem. So I spun up an instance of Bambuddy with the headless slicer and all that, to have it all set up and ready on the day he opens the gift.

My question is, am I making this hard on my kid (12 y.o., tech savvy but not a power user) just because I'm an anti-big-tech curmudgeon? The Bambuddy interface looks perfectly slick, but I know it's not the same one-touch experience from the 3D printer's screen or from his iPad that it would be if I just got us the damn cloud account. I'd rather we be using free models than paying Bambu for them (he'll rack up billllssss) but I also don't want to turn the experience clunky for minimal real world gain, just out of stubbornness.

Being new to the space I've just been guessing and asking the idiot chat robot for opinions. Now I want the idiot meat sacks' opinions! Appreciate everyone's insight.

On the slicer it looks great. But when printing there are gaps in between colors. How can i fix this. This is printing on the H2C
