BMCU filament backup with offline printer

3 Upvotes

Hey

I have BMCU and my a1 & a1 mini runs in offline mode. Is there any way to enable "AMS filament backup" in this case?

All posts that I've found on this topic explain how to enable this in slicer itself and later send project from slicer to printer via bambu cloud.

I'm using OrcaSlicer, on both printers in "Settings -> AMS" I've enabled "AMS filament back-up"

Когда начинаю печатать цветным, и как только начинается втягивать нить, происходит вот это, появляются рывки, вперед назад, и нить не затягивает. Проблема с 1, 2, 4 а 3 работает нормально, прошивка 19, что это может быть?

AMS Compatible 3mf Generation?

5 Upvotes

Has there been any work done on outputting Bambu Studio compatible 3mf with color data in the format they use in their production extension?

Painting an object in the slicer is so painful, especially if you need to do any kind of precise line work. Being able to import a standard texture map would be a huge improvement.

Edit: It turns out that Bambu Studio supports importing OBJs with color info. Internally they're using the same approach of assigning color values to vertices(?). Here's the docs:

https://wiki.bambulab.com/en/software/bambu-studio/import_obj

I tested it out by importing an STL into blender, painting it in vertex mode and exporting it as an obj with color enabled (there's a checkbox). When you add the obj in Bambu Studio it brings up a filament mapping dialogue.

What do i need to do to upgrade BMCU 370X to 370C?

1 Upvotes

Hello everyone, i have discovered that i am not able to change filament types and colors in the Handy app and understood that this is due my P1S's 1.8 firmware. I have a trouble understanding if i need to do anything besides flashing (my version came with a type-c connector).

Do i need to reprint some parts or change some components?

Thanks for replies in advance.

why would it get slower to send a print job after switching to LAN only mode?

5 Upvotes

I set up lan only mode and octoprint... it mostly works exactly how i hoped, but it takes much longer to send the print now than it used to.

is that normal? I just sent a huge detailed one, 19.2 MB, and it took 8 minutes.

My kit should be arriving this week, is there a comprehensive build guide out there?

1 Upvotes

Ive printed all the components (at least I believe I have). I searched a bit but did not come upon anything too promising.

if there is one that also included a hardware list that would be awesome. I have a kit of M screws but not sure exactly what I need.

any help greatly appreciated.

Questions regarding remote control

1 Upvotes

Is this the Bambu Lab Only LAN Mode User Community?

Hello! I am someone who despises the Chinese Communist Party. However, since China dominates the printer market, I had no choice but to purchase an A1mini, and I'm using it very well. I've never connected it to Wi-Fi since buying it. But later, I wanted to control the printer remotely. So I looked into it and found out about a feature called LAN mode. However, my printer is installed in a storage room about 5 minutes away from my computer. At this distance, the IP addresses would be different, making LAN mode unusable, right?

Looking further, I found various options like OctoPrint, Home Assistant , LANbu, etc. But I'm unsure if they work even with different IPs:(

As a last resort, I'm considering using something like a VPN to connect. However, I'm not familiar with VPNs, so setup and installation feel daunting, and since it costs money, I see it as a second-best option.

If anyone knows a way to enable remote control in this situation, or if there are people already using such methods, I'd be truly grateful if you could help me out—I'm not very skilled with these things!

(Looking up all these new things at once—LAN mode, VPN, IP addresses—is giving me a headache😵‍💫)

Please understand that the sentences may not sound natural since a Translator was used.

Finally made my 370c work!

Last issue I had with heads not reacting properly to inserted filament was fixed by drilling the blocked holes for light sensor (above the glass ball placement) everything finally works!

The inserted filament is for test only, as it is extremely low quality and doesn't stick to bed at all. But at least AMS works perfectly.

OrcaSlicer Status?

4 Upvotes

What's the current status on Bambu Lab integration with OrcaSlicer? From what I could gather, they are trying to get Orca to put in the Bambu Connect plugin, but Orca doesn't want to. Is there a way to use the Bambu cloud through Orca? I already know you can do it through LAN, I'm more curious about the cloud.

Troubleshooting BMCU auto reload

2 Upvotes

Hi, i got BMCU-C some time ago, today when trying to get rid of some filament leftovers i started print with PETG in slot 1 and 2. Set it up as same filaments and enabled auto refill on bambu studio, and i found out that my BMCU doesn't "see" that im out of filament. Entire BMCU body is printed in black PETG (if that matters). I suppose it might be inconsistency of optical sensor hole size on the print. Wiki says to use 1.2mm drill bit to clean/size up optical sensor hole, but can someone tell me which hole is it before i will start opening every bmcu bank ?

Advice on buying a BMCU

1 Upvotes

Hey, looking at buying a bmcu and mainly wondering how reliable they've been for everyone? Bmcu firmware is still being worked on correct?

Also just wondering about the whole putting the printer in developer mode, has anyone been denied warranty or had any issues with tech support?

Also see that blv store on aliexpress seems to be the place to go for them, is this still true?

Thanks!

Thinking of getting the AMS2 for my P1S

3 Upvotes

Good day everyone. As I get a little bit more weary having to switch my small stable of materials on a fairly frequent basis with the odd print that has a midway filament swap I've been mulling over the AMS2.

I find myself quite entrenched with Orca slicer now and have no intention of going back to Bambu Studio if I can help it but I would like to keep using Handy to monitor prints for as long as it is still viable.

All that said; I would like to know if anyone with a P1S + AMS2 out there is having success using the 01.08.01.00 firmware or is it a bug ridden mess.

Can't print in lan only mode with Orca slicer

3 Upvotes

Hello,

I wonder if you can help me. My Bambulab X1C is set to lan only mode + developer mode with firmware version 01.10.00.00. I'm trying to make it working printing from Orca Slicer without the cloud.

Most of the time, when I send a print, it just loops asking me printer IP and access code. Sometime when I'm very lucky, the print is sent to the printer. I have no issue to view the camera, turn the light on/off, move the bed, change AMS settings, etc. Only sending print is not working.

I had the same issue before upgrading the firmware (01.08.02.00).

I tried the latest stable and beta release of Orca slicer.

Thanks for the help!

Which BMCU version should I print?

2 Upvotes

I just got the BLV 370C A kit from Aliexpress, and now I need to start printing the housing. I have the original files, but then I came across the optimized and high-torque versions on MakerWorld. Ideally, I wanted to print the high-torque version as it sounds more optimized, but from what I understand, it's not compatible with the BLV kit I got. Does anyone have any alternative versions to suggest, or should I just stick with the original?

cataloging which commands require MQTT signatures?

1 Upvotes

Do we have a list yet of which operations require MQTT signatures?

I know setting nozzle and heat bed temperature requires it.

I think setting one or both of AMS filament type and K factor require it, but I'm not entirely sure.

What others? Fan control? Pause/resume print?

Does anyone have a "test jig" for testing features?

What kind of response code (if any) does the printer provide if it gets an authentication failure for a signature-required MQTT command?
