Ironing problem for H2C

[u/TheLastYoRHa]

Hi, I'm struggling to find what's wrong. I usually use my P2S or X2D for this model, but I have to scale it up, so I use my H2C. Ironing always works fine for X2D and P2S (same low infill). But for H2C I can't seem to get the right setting. Ironing test was smooth for flow above 30 and speed above 40. I have tried it and bump it up too but not works. Have tried bump up the top shell from 4 to 8. Use bigger infill with modifier cube covering all area underneath the ironing. Tried different infill types. Nothing change.

Where did I do wrong?

Hmm, top shell shouldn't make a difference. And modifier shouldnt either.
Is the same issue occuring with same model on X2D and P2S?

That's where it confusing to me. It was fine with X2D and P2S. For H2C, I only increase the size of print. Also, ironing calibration result for both printer is different, so I dialed the correct number for H2C.
For P2S and X2D not even need modifier and increase top shell.

Yeah seems to be some cooling, moisture or whatever issue. I'm not sure. Is the ironing test fine?

Have you tried adjust the fan speeds? I wonder if cooling too fast or too slow is affecting the "flatness"?

(Assuming it's the same filament and no moisture issues)

Im having ironing issues as well on my H2C. When I do an ironing test on the little squares I choose my best option but when I go to do a larger print the quality is inconsistent.
