I finally decided to break out of Bambu’s increasingly-closed walled garden.
I’ve had the Bambu X1C for a couple of years already, and it is a really, really great 3D printer. There’s no question whatsoever that Bambu has transformed the 3D printing space for consumers, and has done so while also creating some very high-quality premium hardware.
I’ve been meaning to write about the various mods I’ve made over time, but at this point it’s a bit far down the line to go into each one in detail 😁
- riser with LED strip, remote controlled via a Raspberry Pi Pico with a simple MicroPython HTTP-to-RF API that can dim the strip
- IKEA SKADIS mounted on the side with tools
- boxes to hold desiccant beads in the AMS, and a hygrometer
- after-market high flow nozzle (obviously)
- Garolite plate
- third party nozzle wiper
- etc etc
The printer has been very reliable, and straightforward to maintain as well.
So why hack it? Well… I own it, I think it can be made better, and… because.
When the X1Plus Expander launched on Crowd Supply I went ahead and backed the project, as I was interested in ways I could potentially add extra sensors and a better camera; as well as finally being able to connect over a LAN socket rather than having to be on wifi (the studio network can be a bit flaky from time to time).
The X1Plus Expander depends on third-party firmware (X1Plus), which requires the printer itself to be jailbroken / rooted.
Long story short, I’ve finally done that.
I was extremely impressed with how smooth and clear the project contributors have made the process. I went through the official process with Bambu to switch my printer into the unsupported third party program, downgraded to a rootable version of the firmware, rooted it, then ran through the remote install process (via wifi from my Framework) to install the firmware. I’d already printed the case for the X1Plus Expander. Then it was simply a case of following the exciting and dramatic installation video.
I now have VNC access to drive the controls on the printer’s touchscreen remotely; SSH access; the ability to network mount storage; etc etc. Lots of options to explore here. I was even able to upgrade the firmware of components like the AMS from within the third party X1Plus firmware.
You’ll also spot the OpenSpool sitting off to the side in the image above. That’s another third-party addon that I’ve barely started to use, but it extends the ability for the printer to recognise RFID-tagged spools from Bambu themselves, to having it recognise “any” spool that I happen to tag and configure.
All of this is background tinkering and admin… apart from the case for the X1Plus Expander, I’ve not been using the printer itself quite so much lately, due to travels.
Open source (and open source hardware!) FTW!
