Describe your issue:
Buenas tardes, primero de todo gracias por perder un momento en leer esto. He configurado la skr con los 2 firm que proporciona skr en github. El firmware uart y usb. Con los 2 tengo el mismo desenlace, mainsail detecta el mcu pero me da el siguiente error:
reporta Klipper: ERROR
mcu ‘mcu’: Unable to connect
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer
proporciono mi archivo print y el log de klippy por si pudieran orientarme ya que llevo toda la mañana probando configuraciones y me siento bloqueado.
