 [klippy.log](https://klipper.discourse.group/uploads/short-url/xjwR7EQ4igaQk8Y1N24B8baxGnF.log) (1.1 MB)

Estoy empezando a construir una impresora 3d con una mks skipr v1.0 y estoy teniendo problemas con los motores, en el software de fluid los motores estan deshabilitados por lo que no me deja moverlos a ningun lado y cuando les indico homing me bota este error “Unable to read tmc uart ‘stepper\_z’ register IFCNT” en otras foros he leido que tengo que aparte de alimentar los drivers tengo que alimentar los motores por separado o algo si llegue a entender.

les agradesco de antemano
