Would have been good if it had worked.

Lo instale en mi CNC 3018Pro y el eje X se mueve en dirección opuesta. Espero el vendedor me pueda compartir un instructivo de configuración. Aparte el Software GRBL Controller lo marca como Estado: Desconocido, aun así se puede mover los ejes de manera manual pero no es ideal para usarlo directamente (plug and play).

This is a specialized controller board for the 3018 type of 3d mill. The fit and finish is excellent. It works out of the box, with added tweeks for end stops and the like. You do have to be aware that this is an unbuffered board made for running SMALL stepper motors and a stock 775 motor. As these motors are an inductive device, disconnecting the wires with power on can cause high voltage kick back which can destroy the board. Any short circuits, bad wiring and the like can easily do the same. The pwm output is aimed at laser cutters and not for larger motor controllers. The pwm output is 12V and can be set to 0 to 100% square wave output with grbl. Most cheap pwm motor drivers expect 5V output and won't work with these boards.

Excellent product

If you are not familiar with electronics - even at a general level - forget it. Buy one with a spec sheet and pinout! This worked great for the replacement of an older Woodpecker driver board I had go bad but no docs AT ALL. For a company with a store front and a decent web presence, how the heck can you NOT supply the least of the documentation. It is not available anywhere I can see on the net and I see others have also complained. Other than that - go for it. Works great!
