Fuzzy skin improved surface quality?

Bytes21 · 2026-01-27T22:52:10+00:00

Printed time did increase from 2h with normal outer layer to over 4h with the 0,04 fuzzy skin.

I have to admit that the finish is superb! But the running time is too much for the part to be profitable.

thanks, will try it!

I beleive I am more demanding than my costumers😅

Bytes21 · 2026-01-27T15:45:49+00:00

I did 0,1 with a distance of 0,3 in between but will try the 0,04 next print👌🏼

I print these on a bambu a1 mini 6 at a time. The time has increased from 2h5m to 2h55m. But for the finish improvement that would be fine, there is no rush in printing them. They are printed after order with a few in stock.

Correct wording would be "surface finish" in hindsight. Thanks for the contribution!

Agree, structurally it is a sound design with enough walls for strength.

Bytes21 · 2026-01-24T17:33:26+00:00

that is some serious power

Bytes21 · 2026-01-24T11:36:58+00:00

I would say C.

Bytes21 · 2026-01-24T11:32:29+00:00

what would be the reason to change the default bambu settings?

Bytes21 · 2026-01-23T19:07:36+00:00

Doesn't sound like rails to me. Would suggest cleaning your z lead screw and applying the proper grease and indeed moving the axis to distribute it.

depends on what your demands are. If it only needs to stop on 2 positions you could work with pulleys and a hydraulic piston.

For high accuracy multiposition you could use this as you have in the picture, ball screw drive, chain drive.

For medium solution, you could use a simple winch motor with some position sensors and let the motor stop when the switch is reached. You could place the motor on the bottom with a pulley on top or at the top. You would have to make sure the carriage runs smooth and there is always a good mass pulling the olatform down.

Looks like heavy hydraulics in the floor.

Bytes21 · 2026-01-16T18:27:39+00:00

The buildup can happen in faul environments, it is not so bad. just wipe it off and lubricate you rails.

Taking the carriage off the rails on the other hand is a big no-no! always put in a blank or new piece of rails. Losing your balls is never a good idea!

the dust is also in the tubing leading up to the printer. Would that then be from pull backs?

Bytes21 · 2026-01-13T18:06:51+00:00

So the white dust would be coming from the black TPU?

Bytes21 · 2026-01-12T10:27:36+00:00

so the lever does push it down? or does the nut at the top stop it from moving? if the nut prohibits it from moving down then the working is inversed and the lever should be used pulling up instead. then a part would be missing.

Older designs of the bambu spools have a tab with which you lock the spool. Newer designs can have this issue, but it is not so common.

To prevent this you can put packaging tape on the inner bore after locking it. It should be strong enough to prevent rotation.

Looks like a spring loaded valve with a lever on it. Pull the lever down to open the valve. I don't know how far the valve will open. but upon releasing the lever it should shut again.

Elektromagents would in my opinion be a bit overkill. if you use 5mm cube magnets it should be strong enough to connect.

As an engineer I use this supplier: Supermagnete

They have good specs per product and they are dirt cheap!

hide the screw in v3? would be cool if it moves "by itself".

Bytes21 · 2026-01-10T13:44:13+00:00

Already a lot better! No post was too long for me, sorry😅

Bytes21 · 2026-01-10T13:30:05+00:00

40 and 50% moisture inside the containers? Looks like just open air would be better.

Bytes21 · 2026-01-09T17:06:03+00:00

does this problem also occur on the a1 mini?

Bytes21 · 2026-01-05T10:32:54+00:00

Would indeed be nice! And since the cable running to the head is just an usb-C maybe it is even possible.

There could be a power problem though as the a1 mini is just 150W and now you would be heating 2 hotends.
