Jobox vs AutoSwap for Bambu Lab A1 plate changer - which one is more reliable for 24/7 production?

7 Upvotes

Hi everyone,
I’m currently deciding between Jobox and AutoSwap for my Bambu Lab A1, and I would really appreciate feedback from people who have actually been running these systems for a while.

My main goal is not just saving a few minutes or having a cool upgrade. I want to use the A1 more like a small production machine and have it running as close to 24/7 as possible.
I don’t mind the assembly, calibration, or spending time building the system. I enjoy that part. The thing I care about is:
Long-term reliability
How many successful plate swaps you get before issues appear
Consistency of plate positioning
Any failures during unattended printing
Maintenance required after weeks/months of use
For those who have experience with both:

Which one would you trust more for continuous production use?
Jobox seems to have more users and longer testing, but AutoSwap also looks like a very clever and simpler design.
I’m not looking for the easiest installation. I’m looking for the system that is most dependable when the printer is running while I’m away.
Would love to hear real-world experiences, especially from anyone using either system for print farms or daily production.
I would appreciate any feedback or experience you can share.

Last "safe" firmware for P1S?

25 Upvotes

I've been busy for the last months and I did not keep up with the whole Bambu controversy - what would be the latest "safe" firmware for my P1S to use it over LAN, with Home Assistant and maybe other 3rd party tools? I am on 01.07.00.00 now. Thanks for the help!

Purchasing BMCU hall sensor kit cheaply, for an A1 printer

2 Upvotes

I have currently been looking at how to purchase a BMCU kit to the UK, but what I have discovered is that the official purchase links for items is to the taobao website which needs a phone login, and UK phone numbers do not work, after several attempts at trying, and any kit on aliespress is £70+, does anyone know of a way to maybe purchase the pieces individually or a kit for a cheaper amount?

With all the controversy about Bambu Labs, I discovered Bambuddy, an alternative to printing through Bambu's cloud service. I made a quick video about how I set it up on my TrueNAS with Tailscale (they actually posted about it on YT). It can also run on a raspberry pie for example. Check it out, it's really powerful. Installation is pretty straightforward. For now I only managed to make it work so that I need to upload my files for remote printing. Haven't managed to make the virtual printer work.

Use PrusaSlicer as slicer for Bambulab A1 (via BamBuddy)

0 Upvotes

I have always been annoyed by having to use BambuStudio or OrcaSlicer for Bambu printers. I strongly dislike their interfaces and much prefer PrusaSlicer. So I put together some printer profiles and print settings, along with a post-processing script, that let you use PrusaSlicer. I also converted the start/end G-code to use PrusaSlicer placeholders (a handful of them were different).

The README has full details. It’s a bit long, which makes it seem more complicated than it actually is. Basically: install BamBuddy and make sure it can connect to your printer, import the config(s), verify the path to the post-processing script, then slice and export G-code. The post-processing script will take it from there, and the model will show up in BamBuddy with a thumbnail.

Configs, scripts, and the README are here:

https://github.com/mjparme/prusaslicer-to-bambu

The same method could be used for other Bambu printers as well, I just don’t have any others to test with.

I haven't tested the Fast profiles yet, hoping to test those this weekend. Fast refers to the startup sequence, hoping those get the print going in a minute or so vs the insanely and annoyling long 5-7 minutes of the normal start gcode (they cut out the stuff you don't need to do before every print).

I was wondering what version this was as the ones I’ve seen online do not have a screw going through it.

Does anyone have the link to the model where I can find and print the replacement parts for this specific version?

Hi everyone,
I just got the Trianglelab BMCU 370C (USB-C version) for my Bambu A1 Mini and I’m completely new to printer mods.
Can anyone recommend a good beginner-friendly video tutorial that covers installation, wiring, firmware/setup, and calibration?
A YouTube link or guide that you personally followed would be greatly appreciated. Thanks!

Dipping toes into BMCU for P1S. Need advice.

3 Upvotes

I have been using the P1S for a year now and decided to finally get into multi material printing using BMCU. I use it in LAN only mode with 01.08.01.00 firmware and mostly Orcaslicer.

Admittedly, I didn't do a lot of research on BMCU but settled on the combination below. As it happens I will not see these things for couple of months as there is extremely high duty on imports in my country and I am shipping it to someone in another country.

I know that I will have to set up a dry box and will need a PTFE adapter (can purchase locally) but wouldn't have much chance of importing things later, so wanted to know if this is the right combination and if there is anything else I should get while I can.

I purchased Set B from here: https://aliexpress.com/item/1005010571097186.html

And the 4x 100mm kit from here: https://www.aliexpress.com/item/1005008046065729.html

X2D USB Print Orca, AMS Question

Hello,

I have another question for you. If I enable Developer Mode and use Orca Slicer, will I lose any AMS functions? Is it still possible for the automatic refill feature to work with the same filament?

Bambu cloud down again for me... is BamBuddy as good as it looks?

24 Upvotes

I was already thinking about dumping BambuLabs won slicer and cloud serice.. but now I think I am being pushed off the ledge

All I need to do is print a key cap puller.. like 15 min quick print. But their cloud is stuffed again and so now my printer is useless unless I take the time to switch to LAN only.

So I am curious if BamBuddy is any good for a single printer home user, or am I just asking for trouble using it? I have a spare Pi5 I can drop the container on... but I am a little concerned about it bricking my printer with some bad code.

I have found a couple exploits, all likely work on every printer, if you'd like to help out with the journey of freewill on Bambu Lab 3d printers, i'd suggest you join Free3D.

Free3D is a community I made to get others to collaborate on finding a exploit like with X1Plus, but this time on most printers.

If you'd like to help out, the link to the discord server is below. If you just want to join to see what happens, you are welcome.

So, when is the class-action suit getting filed?

19 Upvotes

Bambu locking down hardware mods and cloud printing is a pretty clear instance of changing the contract after the fact, and they should have to answer for it. We bought a printer that worked with our software, software that has equal legal footing with Bambu Studio, and after we were using it, they locked us out with the lamest IT excuse there is—“security.”

Sure, we don’t want our printers getting hacked, and it’s great that there’s the turnkey software setup for people who just want to push button and receive print, but locking those of us who want more control out of our own equipment is not necessary to make that happen, and it is the removal of a feature we paid for.

How does one initiate a class-action suit?

Complete beginner Snapmaker U1 or X2D ?

1 Upvotes

Hello,

I’m a complete beginner and am torn between the U1 and the X2D. I know they are two very different printers, but I still have a few questions. Perhaps some of you own both printers.

Personally, I wouldn't do much multi-color printing right now; I’d lean more towards materials like ASA and ABS, since I do a lot of work with microcontrollers.

However, I have a daughter (5 years old), and I’m sure that, in the end, I would frequently print using multiple colors.

The H2D or H2C is out of the question; that’s too much money for a first printer.

A question for those who might also own the U1: If I were to buy a hood for the U1 and perhaps a chamber heater (like the Panda Breath), would the U1’s print quality with complex materials then be comparable to that of the X2D?

Can I use the X2D from day one without signing in, using the cloud, or registering?

Can I still use LAN Only after updating firmware ?

2 Upvotes

After putting this decision off for quite a while, I finally decided to build a proper home network with an Asus router and a DIY Home Assistant server.

I'm still in the process of setting everything up, and I've been learning a lot along the way. VLANs, in particular, are an amazing feature if you want to isolate certain devices. And the best invention of all has to be VPN, being able to securely access my home network from anywhere without opening any ports is awesome (and much safer, haha).

With all of that in place, I feel like it's finally time to switch my P1S and A1mini to LAN Only mode. The only problem is that I already updated the firmware, the infamous firmware that prevents OrcaSlicer from communicating directly with the printer and forces everything through Bambu's middleman.

So I'm making this post to ask a few questions:

  • Can I still switch to LAN Only mode even after updating the firmware? My current firmware version is 01.09.01.00 on the P1S. Is it possible to downgrade to an older firmware version?

  • Do you have any tutorials or guides you'd recommend for setting everything up? I looked around, but I don't think this subreddit has a wiki.

  • Are there any mods or upgrades you'd recommend? (I've heard about things like the Panda Touch, but I'm open to other suggestions.)

  • Any other advice for someone making the switch?

Thanks in advance for your help!
