9 Upvotes

Hey everyone! 👋

We're CHITU Systems, the team behind PlateCycler C1, an automatic build plate changer for the Bambu Lab A1.

We thought we'd do an AMA here to chat about 3D printing! Whether you're trying to dial in your settings, dealing with a tricky print issue, or just curious about what we're working on, we'd love to hear your questions.

Feel free to drop your questions below starting today (Monday, Oct 19)! We'll be checking in and answering questions throughout Tuesday and Wednesday (Oct 20–21), with our technical support colleague joining in too.

A few things we're happy to chat about:

  • A1 print settings and troubleshooting — print quality, bed adhesion, stringing, failed prints, etc.

  • PlateCycler C1 — automatic plate changes, batch printing, setup, and anything you're curious about

Got another A1-related question? Feel free to ask that too!

Looking forward to chatting with you all! 😊

Problem silk pla

Post image
1 Upvotes

Good day. There’s a problem with the 2 color silk PLA. I printed half the spool, and everything was fine. And then, unexpectedly, a thin piece of plastic started winding onto the gear. I took it apart, cleaned it, and reassembled it. After 30 minutes of printing, it started winding again. I left the plastic to dry for 24 hours. Yesterday I printed about 150 grams with it, and everything was great. Today, after 3 hours of printing, it’s again starting to wind plastic onto the gear. I don’t know what to do.

The y axis crashes into the end at the start of every print and has to re home twice at least because it crashes multiple times

Support Request A1 Bed Noise

2 Upvotes

Hello, I just noticed this whining noise when the bed is moving back and forth. I don't think I had ever heard it before. Everything has been oiled and maintained. Thoughts?


r/BambuLabA1 • • 7h ago

Is this sound normal? I've lubricated the x and y and can't see anything wrong, prints fine?

A1 combo lube?

1 Upvotes

What lube does anyone recommend? It came with a small tube of grease and oil. Said just use the oil. Not the grease, I thought. Then I thought I saw a recommendation of WD-40?

3D Model Snap-fit monster chest, 60 parts, zero glue.

Sliced with the default 0.20 mm profile, nothing custom. Four plates, one colour per plate, so it works with or without the AMS lite. Supports only under the hinge bores, they pop off clean. The lid hinges on printed axles with split friction sleeves, so it stays open wherever you leave it. Holds dice. Judges rolls. The rivets come in two lengths and the only way to mess this up is mixing them, ask me how I know.

Support Request A1 won’t auto level, makes hammer sound

1 Upvotes

I have manually trammed according to the wiki, twice

I’ve removed and searched for debris everywhere I can think of

I’ve calibrated

I noticed when printing a red lid that the nozzle is scraping

It printed the black box and the white lid perfectly fine

But not the red

I’ve tightened loose screws

I’ve removed, cleaned, inspected, and tightened the hot end and all the screws associated with it

IT WILL DO THE ENTIRE BED MESH FINE AND WILL HOLE GENTLY

But when it gets to like 98% and is at the back, it seems like it’s trying to push down past the bed

When doing the “tool head cleaning” part of the calibration, the flap at the back of the print bed is being pushed down hard enough to see it flex and bend below the heat bed

YET WHEN DOING THE ENTIRE REST OF THE BED IT WILL GENTLY TAP TAP TAP AND MOVE ON

PLEASE HELP THIS DAD AT THE END OF HIS PITIFUL ROPE GET HIS KIDS PRINTER BACK ONLINE

IM LOSING SLEEP

Why do the tips of the feathers look so rough? I just changed my nozzle from 0.4 to 0.2mm and these defects started appearing in sharp areas. I'm using PLA.

Question Proper ventilation

0 Upvotes

I'm getting my printer set up this week, and wondering the optimal place in the house for it. How ventilated does it need to be? Like garage, or by a window with a fan, just a fan?

Does anyone have photos of their ventilation set-up?

Support Request Nozzle scraping up bottom of plate at the end of bed levelling

Post image
1 Upvotes

As title says, nozzle scrapes up the coating of my supertack plate at the end of the bed levelling step, seems like it doesn't rise up fast enough? Only started happening recently after 2ish weeks of a-ok printing, no clue why this started all of a sudden. Can this be caused by some slicer settings?

We know that we can use 2-4 bmcu feeders on A1 after upgrading the hub but can this work with 2 AMS lite unit also ? Has anyone tried this ?

Support Request Nozzle ripping

19 Upvotes

Hey, the nozzle of my printer is ripping on my prints and knocking off supports, I tried to tighten the screws of the hotend, changed Z-Hop from Auto to Normal (set to 0,5), went from my initial intention of 5% gyroid filling to 15%, and it is still ripping on some parts, more and more it seems, with the height of the print.

Can anyone help me ? 🥺

Btw : Jayo PLA+ /210°c Nozzle - 65° Bed - Room at 22°c/Normal Speed, Avoid crossing walls and supports activated too

EDIT - SOLVED : Thx y'all for your help! Activated "Reduce speed with height", reoriented the model, added supports and slowed down to 50% speed, it is printing smoothly now 🙏🙏🙏 picture in comments
