GRBL 32bits board Presentation

GRBL 32bits board kit is a 4-axis CNC control kit.

Its particularity is that it’s autonomous, it can fully manage the CNC without a computer thanks to its TFT touch screen, but it’s of course possible to connect a computer via USB or WIFI!

Complete solution, powerful, precise, easy to use and to implement thanks to the tutorials, it’s as well adapted for the beginners as for the experienced ones, all for a very low price!

  1. Bonjour,
    je m’intéresse sérieusement à cette machine, j’ai commencé à imprimer les pièces et c’est en bonne voie.
    pour diverses raisons, je préférerais avoir la platine d’accueil du Z usinée en alu,
    Auriez vous un lien pour faire fabriquer cette pièce ?
    En vous remerciant d’avance.

    1. Bonjour Thierry,
      Je n’ai personne à recommander pour ce travail, mais c’est tout de même relativement simple à réaliser dans une plaque d’alu 8mm, avec une perceuse et une disqueuse.
