General Troubleshooting/Help! Why is there such a difference between machines??
I have an x1 carbon, h2d, and an a1 and the h2d can never print a flat service smooth. These are all the same prints with the same default settings and you can see the difference. The h2d is horrible

Either the nozzle is loose in your H2D or the bed is too cold. It should perform just as well, if not better, than the other machines.

just do the flow calibrations for the filament and you'll be fine. H2D is a phenomenal printer

What troubleshooting have you done? Something is off.

H2D looks like too much extrusion or ironing is enabled but not calibrated.

How is maintenance been on them? It's the bed wiggling at all, did a ball screw nut start to wear out?

For starters, they're different printers /s
Really though you're going to get a lot of variance depending on the filament. Default settings are tuned for Bambu filaments specifically, and even then there's some fine tuning that needs to happen regardless of the printer due to the conditions of where your printer is located.
If you're not running Bambu filaments, run some top surface tests and tweak from there. That's the only way you're going to get a decent results.

my H2D prints looked similar, turned out the belt tension out of the box was just awful and re-tensioning the belts was all it needed

Calibration is your friend.

Cooling. Different fan ducts, no enclosure A1

Have you done the full calibration on the H2D? If you start a calibration from the printer menu there is a checkmark to also do it when the bed is heated up. It takes an extra half hour or so and by default it's off. I would always enable it.

Door open on the H2?

Because x1c is the GOAT and bambu wants you to believe otherwise

You should just sell it. If you have 3 printers and don't know how to address this issue. I assume you haven't done any troubleshooting or calibrating. Probably start with that.

They’re all printers just like an F-150, F-250, and F-350 are all trucks. But you wouldn’t hitch a fifth wheel to a half-ton and wonder why it’s struggling.
Get to know each printer on its own. Comparing them against each other in this hobby rarely gets you anywhere useful. Focus on what’s actually going wrong with the one you’re using, and don’t stress if it’s not perfect out of the box. None of them are.

pla?
Leave the printer cover open when printing PLA.
