H2C Top surface quality issues

Hello all,

I’m having issues with the top surfaces of my prints, On my P1S and X1C printers I have no issues achieving a quality top surface layer. I run ironing tests to set my flow and ironing speeds accordingly. Below are some images of the issues. Both the streaking appearance and the appearance of what looks like under extrusion.

On the P1S, I’m able to achieve the following result…

I would just use the few P1S I have dialed in, but I’m wanting to start make larger signage. I feel like I’ve tried most things, but maybe I’m missing something, any help is greatly appreciated. Thanks in advance.

Sounds like you might be experiencing a similar problem im having. Ive shared some of my experiences so far in this other forum thread.

Yeah i saw that thread, but I didn’t notice anyone having the tool marks that i have in the second photo with the pig head, I thought that although they look similar mine looked like a slightly different issue. I purchased the machine on preorder. I imagine it is one of the first batches.

I cant open a new topic yut, but just to say I’ve had a P1S for 2 years and was able to quickly dial in ironing settings for Bambu PLA Matte. I’ve spent the last two weeks though trying to do the same on the H2c, going through countless hours of filament drying, filament calibrations, ironing calibrations etc and I’m still no where near the results i can achieve on the P1S. Very frustrating given the cost of this device.

If anyone has any tips or tricks specifically for ironing on the H2C which go beyond the typical “calibrate your ironing”, add x% flow I would very much like to hear them, thanks!

Same story on X2d.
