Klipper config problem with Tronxy x5sa 2e

General Discussion
1

Hello,

I have a Tronxy x5sa 2e. A week ago I wanted to print with my second extruder. So I tryed to configured the print.cfg file. Unfortunately I can’t get any further. I added the 2nd extruder and the T1 and T0 macros too. On my printer’s clipper screen I can select the 2nd extruder, but it doesn’t work. The cable and motor work perfectly.

My guess is that the wrong pins are specified. However, I don’t have a blueprint of the Ch… v6 board. And I have no idea what the difference is, e.g. PA8 to PB8 to PC8 and so on.

I would be very happy if you could help me.

and a big thank you to Kevin o Konnor

Hello @LuciDude !

Are you sure about these pins used twice?

  • enable_pin
  • heater_pin
  • sensor_pin

Yes, because Klipper says I need them.

Of course you need them, but each hot end has it’s own pins for enable, heater and sensor.
You have to investigate what the correct ones are.

I got only 1 header and 1 nozzle, but 2 extruders. I only got 1 sensor and 1 header. So i have to dubble use that 3 pins.

6

I see - that makes sense

I have doubts that this is going to work:

  • Duplicate sensor pin: Your reading will be way off when you connect two sensors to the same pin
  • Duplicate heater pin: Both heaters will be active at the same time, effectively doubling the load in the MOSFET, which might fry as it is not meant for such a load.

Apart from this, it is not a “real” dual extruder but a 2-in-1-out. You might want to check X-In/1-Out Non-Mixing Extruder Config

Has anyone got the x5sa 2e to work with the extruder properly ?
