# Bambu Lab Klipper Conversion!
Welcome to my page! The goal of this project is to have a **fully non-destructive** upgrade path to [Klipper](https://www.klipper3d.org/), on a Bambu Lab P1S. This means replacing the existing electronics with open-source hardware. My project right now is in the works, but should be fully working hopefully soon. Stick around for updates!

To start.. Why the hell not?! Putting open-source hardware and firmware on a closed source printer is hilarious. But for me personally there are so many benefits. All of my printers at the moment all run on Klipper, using the same exact Web UI. I'm familiar with it, I enjoy using it and I enjoy being able to make easy simple changes with a quick change of a text file. So adding Klipper onto my P1S is absolutely worth it to me. Once I get my heated bed to work, I will be able to run it at higher temperatures than 100c (It's an AC bed, it being software limited is absolutely ridiculous as it is the same bed that is used on a X1C)
Upon further inspection the SSR appears to be reusable, I need to probe the pins with my multimeter to find the controlling pins in their PicoBlade connector. Then I can wire those up to the new control board for controlling the AC bed.
My P1S has always struggled to print filaments like ABS and ASA without warping severely. And having Klipper on it means that I can also start adding other hardware to help. Such as a PTC heater to actively heat up the chamber. Adding a chamber thermistor to actually monitor to temperature inside. Adding a touchscreen onto the printer so that the horrible display before it no longer has to be used. The list can really go on and on!
Bed thermistor is confirmed as a NTC 100kΩ 3950. Can be configured as Generic 3950 in klipper config. Shows accurate temperature readings from my old bed, which I removed and added my own JST connector onto.
# "How hard is it to convert?"
The piezo sensors appear to be reusable in some way, just need to figure out the wiring to them and then configure them as needed in klipper.
Not hard at all! The cost is super low, and since it's non destructive, everything is basically just drop in and go!
# Here are some images of the project thus far.

I have designed a quick PCB from JLCPCB that can convert the stock PicoBlade connectors of the Chamber Exhaust fan, and Aux Cooling fan, to be easily converted to a JST connector. Just plug and play. Will test if it works once those arrive, these are ridding of the PWM control sadly, so I am unsure if they even work. Atleast not at their true full power. But I will test their functionality as soon as they arrive.
