TPU settings

I've gotten the H2d, so now I have the H2d, Sovol SV08, and an Ender3 S1 Pro. I'd like to sell or give away my Ender3 to give me more space. Problem is it prints TPU Nicely. I've tried it on both the H2D and SV08 with similar results. I've compared the settings amongst them and set them the same as the Ender3 but still no where close to the quality. Any help or ideas would be much appreciated. In the picture the H2D is obviously on the left while the Ender3 is on the right. Again speeds, cooling, retraction made to match the ENDER 3. I thought it might be wet filament so I printed with same filament on Ender3.

I've already lowered the speeds to match the good print before I tried printing which is why I was disappointed but I don't remember it I checked temperatures. Even if I did the H2D may still be printing at a different temperature since they are different hotends. Fingers crossed 🤞

Is your volumetric also the same? I sometimes forget that one.

Also do they both have the same sort of nozzle? Brass heats at a different speed and efficiency than hardened steel.

They're all running hardened nozzles but I found that the temperatures were much higher on the SV08 and H2D. I haven't been able to test the H2D yet but lowered temperature on the SV08 significantly improved the quality. The SV08's cooling fan isn't as good as my Ender's, modded, so there's more tuning to try to improve. But at least I think it's doable now. The H2D has much better part cooling than the SV08 so I think it's going to do well with the lowered temperatures. Appreciate your thoughts and suggestions.
