I iron almost all of my etsy prints on my 5 X1Cs and get duplicable results consistently using the same settings across all of them, but I have yet to get a single good result on my H2D sadly. I use almost all Bambu Lab filaments.
I have tried most of the top downloaded calibration tests, but despite dozens of hours of calibration prints, there’s other variables in play that I’m not duplicating that cause under extrusion during ironing a large piece that just end up ruining the piece.
Does anyone recommend one of the calibration tests over others? Here’s some examples of my issues:
On my X1Cs I iron almost everything at 30/25 (speed/flow) and get perfect results every time:
On my H2D shose settings don’t work so I’ve done several calibration tests that look fantastic, but when printing one of these large box lids either it starts out great and ends up terrible, or the edges get underextruded:
not sure if it works but for PLA, try turn off auto flow dynamics calibration and just use 0.02 as the k value, that edge issue seem to be related with it. with auto calibration it often lands on ~0.033 and I have not yet seen anyone who has posted an auto calibration value that is in range of ~0.02.
I’m skeptical but curious since I calibrated these filaments before printing and always do to ensure quality, but you’re saying don’t trust it and go with a static value and try that?
You can try to do a PA calibration yourself. With auto you would always get some value at the range of 0.033 ish (for PLA basic). But if you do pattern based manual PA you would always get something like 0.02-0.024.
I use the same settings I use on my K1C and it’s turned out great with the H2D. 150mm/s 26% flow, 0.2mm for spacing/inset. I haven’t completed any prints with that large of an area to be ironed but I’ve had good success with most everything else, have you tried faster speeds?
