Reduce the extruder wires of your 3D printers

Updated: Oct 28, 2021


PandaCAN is an extruder control board that connect to main board with CAN interface, more resistant to noise,reduce a lot of wires for your 3D printer.


Why CAN bus ?

CAN(Controller Area Network) is a robust serial communication bus found mostly in automotive and industrial environments.

  1. Resistant to noise, you will have less signal noise and wiring problem.

  2. Reduce the wires from more than 19 to only 4. 19 = hotend cooling Fan: 2 + model cooling Fan: 2 + heater: 2 + temperature sensor: 2 + BLtouch: 5 + Extruder motor: 4+Runout sensor:2

  3. High data rate 1Mbps.

Mark, how do you run the PandaPi v2.9 board in Stand Alone Mode? It says without Raspberry Pi, but it wil have no internet wired or Wi-Fi then. The small screen is certainly not an optimum means of controlling a printer.

Mark, In your October 7th post, you mention and show images of "Reduce the extruder wires of your 3D printers" using a CAN bus adapter board to 'reduce 14+ wires to just 4' that you've created. That sounds great, but you don't list it for sale. Will this become a product for sale?
