Hola no encuentro las aceleraciones normales para una prusa i3 alguien tiene alguin ejemple gracias y buenos dias

Hola, esas que aparecen en esa configuración son perfectamente válidas para una impresora tipo Prusa i3, las encontrarás en casi todas las configuraciones de ejemplo que tiene Marlin para ese tipo de impresoras.
No hay que obsesionarse con las aceleraciones, solo adecuarlas a la rigidez de la estructura de la máquina y ajustar correctamente el Junction Deviation o el Jerk.
En este caso está el JD activado y con un valor correcto para esa aceleración: a partir de él puedes jugar a variar su ajuste, si ves que te hace mal las esquinas, aunque no deberías tener problemas con esos valores.

si te entiendo solo por preguntar si estaban correctas me quedo tranquilo voy probando
lo que paso que imprimí con filamento gris y quedo muy rayado y pensé que las aceleraciones estaba mal por eso preguntaba
pero es el filamento que es muy jodido de imprimir
muchas gracias compañero un saludo
