You can create an own one

The reason you get no proper answer to your queries is, that obviously no Spanisch speaker here can help you.

Actually this is an English support forum. Try to formulate your issues in English.

I have flashed the board and in kiauh it flashes successfully but my question is, do I have the board connected to the BTT PI without any motor or sensor or anything, is that why I do not have access to the printer controls in mainsail?

You might have a look to your klipy.log!

> Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-FTDI\_FT232R\_USB\_UART\_A10K2KRW-if00-port0

You might look here [https://klipper.discourse.group/t/how-to-trouble-shoot](https://klipper.discourse.group/t/how-to-trouble-shoot)

…but I guess after fixing that you might run into new trouble
