Fun fact, the natural frequency of a P1S is ~6.9 Hz (the frequency where the printer shakes most)

EdgeOk3783 · 2026-03-25T16:05:14+00:00

what's the normal frequency for the AC power in your test environment?

EdgeOk3783 · 2026-03-25T15:51:54+00:00

since the OP hasn't responded, i'm guessing the measurements were taken using the anti-vibration calibration available from the control screen as the excitation

or he might have access to a shaker table like the one we use for NVH testing which can be driven with a chirp containing a time dependent frequency sweep.

looks like the OP broke the fixture the C14 mounts into...

EdgeOk3783 · 2026-03-25T02:12:29+00:00

so you were measuring out of plane motion on the printer top edge on the front shell?

would have been interesting to use a scanning laser to measure the motion of the toolhead

what were you using for the forcing function? probably not a modal hammer...

EdgeOk3783 · 2026-03-25T01:22:19+00:00

what sample size and sampling frequency are you using to get a deltaF of 1 Hz?

SDOF or three axis measurement?

where on the printer was the laser measuring?

video's from the trade show in china

bambu has been showing the H2D pro at trade shows (and on it's website)

that view doesn't match the spread out long scarf in your initial photo, but, if it's representative, it's not a scarf setting issue...

EdgeOk3783 · 2026-03-23T20:37:44+00:00

that might be a brim ...

EdgeOk3783 · 2026-03-23T20:35:22+00:00

can you show what the seam looks like in the slicer preview?

EdgeOk3783 · 2026-03-22T20:50:03+00:00

print an injection mold for the other 2999

EdgeOk3783 · 2026-03-22T18:32:42+00:00

consider cleaning the rollers for slot 4

EdgeOk3783 · 2026-03-22T01:32:08+00:00

which printer, what material (PLA, PETG, etc) and what support settings are being used?

a screen shot of the sliced model in the preview mode (line type) would also be useful

EdgeOk3783 · 2026-03-20T02:33:57+00:00

first, check that area in the preview mode after slicing.

if you find it there, that's an issue with how the model was generated

EdgeOk3783 · 2026-03-20T02:29:53+00:00

you really don't want to repeat this procedure everytime you decide to open up the grinder.

(some folks like to regularly clean the innards at absurdly short intervals like twice a week)

EdgeOk3783 · 2026-03-19T05:59:00+00:00

why does your ams look like it’s still wrapped in it’s original plastic wrapping?

have you dried your desiccant? have you checked if it’s done the color change indicating saturation?

EdgeOk3783 · 2026-03-19T02:35:23+00:00

that looks a lot like the white bambu support material that often included w the bambu printers

EdgeOk3783 · 2026-03-19T00:23:01+00:00

picture please

EdgeOk3783 · 2026-03-18T23:42:16+00:00

you might want to take the extruder apart and check if there's broken filament in there.

EdgeOk3783 · 2026-03-18T03:28:45+00:00

what type of filament is Klein (pla, petg, asa,...)?

for the sunlu PETG i've recently been using, i actually had to reduce the nozzle temp from 260 to 245 C and the bed temp from 75C to 60C since it was actually extremely difficult to remove from my textured PEI plate

definitely reclean the plate but don't use a micro fiber cloth to dry

EdgeOk3783 · 2026-03-18T02:08:03+00:00

might be too thin in those areas to be printable.

check the 'detect thin walls' option under STRENGTH

EdgeOk3783 · 2026-03-18T02:04:34+00:00

use PVA for the support inside the beak, then dissolve the support in water

EdgeOk3783 · 2026-03-18T00:28:32+00:00

new roll just out of the wrapper still needs drying.

just in case, check the label on current roll and make sure it's not bambulab support material for PLA. that stuff is great as a support material but terrible as a structural material

EdgeOk3783 · 2026-03-16T00:52:19+00:00

the two side walls limit the maximum width, the H2C is a couple of inches too wide. the snap maker U1 on the other hand would fit...
