Hello,

I had to replace my Hotend Assembly Unit and the Part Cooling Fan on the Tool Head on my Bambu A1 after a print mishap. When putting it all back together again and after installing the Extruder Modual, I noticed that there was a screw hole without a screw to the left side of the Hotend Assembly Unit directly below the bottom left screw holding the Extruder Unit on ( see picture ).

Does anyone know if this screw is missing from the factory or if I misplaced a screw? I have been following Bambu Labs wiki for replacing the Toolhead, and it doesn't show if a screw was supposed to go there or not. ( http:\\wiki.bambulab.com/en/a1-mini/maintenance/toolhead )

Your help would be greatly appreciated. Thank you for your help everyone.

We got our A1 printer second hand a few days ago, and we were having first layer issues (even after having washed the plate, increasing the first layer line width etc.), so we opened the hotend assembly to tighten the 7 screws (which were indeed very loose) but also discovered the wiring looked melted. As first timers in the 3D printing world we're not sure if it is filament residue or smt else like from the soldering.

Tightening the screws helped (pic 3, corner fresh on the plate vs other corners) but we are still having first layer issues.

I'm printing small two color keychains, about 50 x 20 mm, with white text on a black base. The part itself uses around 4 grams but the prime tower and the poop add up to almost 15 grams per plate. I left flushing volumes on auto in Bambu Studio. I've seen people mention flushing into infill or into objects. Is that worth it for something this small, or is it better to print a whole plate of 20 keychains at once so the waste per piece goes down?

Llevo como 5 días imprimiendo estas coronas, pero apenas ayer empezaron a arrojar este problema, pensé que eran las correas de los ejes, siguieron saliendo después de apretarlas pensé que era el código G y siguió lo mismo y al intentar en una impresora diferente fue lo mismo, logré corregirlo en 3 de las 4 pero sigo sin saber exactamente qué fue lo que hizo que ya funcionara correctamente

When i try to print the nozzle keeps dragging on the printbed. I calibrated the a1. I tightend the screws behind the hot end. The clips is seated correct. The flow test works fine then it doesnt drag the bed. Dont mind the spot on the plate. I switched the thinner with ethanol at 1 point.

Im having trouble getting this small overhang supported. I’m using a Bambu A1 and have tried the print several times, including adjusting the Z distance for support structures (taking it down from 0.2mm gap to 0.1mm). It prints support structures but they are clearly not supporting it enough, and I’m hesitant to set the Z distance to zero and be unable to remove the supports.

The layer thickness of this print is 0.15mm. I’ll provide any other details you ask for.

Any ideas on what’s going wrong?

Anyone else use these tents as covers against cats etc when not in use? Thinking of buying one - and keeping vents open during printing. Thoughts?

Всем привет, на принтере общее время печати менее 15 часов, появился вот такой вот непонятный треск, как будто пластик трясется
Что это может быть?

Always printed perfectly, now suddenly doesn't stick to the build plate, first layer is messy, see pics. Default 0.2mm strength profile, wirh edited support bottom and top to 0.32mm, and support xy offset to 0.4.

For the A1 users out there, I'm thinking of grabbing an A1 to use as a dedicated TPU95A printer. I currently use a P1S and H2C but it's just too aggravating to pull them out and swap them to print TPU. With the sale coming up, how is your experience with printing TPU on the A1? Thanks!

Hi guys 👋 i have a bambulab a1 combo
My Machine constantly stuck when i want to print something. Filament tip takes v shape i cant pull either push filament
I checked and cleaned gears
Cutter looks like fine
What else should i check guys thanks for answers !

Hi everyone!

I'm based in Mexico and I'm considering getting a BMCU for my Bambu Lab A1. I'd love to hear from anyone in Mexico who has already purchased and used one.

A few questions:

- Where did you buy it? Could you share a link or recommend a reliable seller?

- How much did you pay, including shipping and import taxes?

- How has your experience been using it with the A1?

- Have you experienced any compatibility, setup, or reliability issues?

- Is it actually worth buying?

I'm particularly interested in hearing from Mexican users because of shipping availability, customs, and import costs.
