Bonjour à tous
Pour changer des Chinoiseries habituelles (je ne devrai pas en dire du mal, j'ai une 3 axes et une 4 axes de 3ème génération avec affichage et pad de commande manuelle),
j'ai trouvé sur la baie un truc Canadien (SoC Robotics) 4 axes à TB 4560, multi interfaces (//, usb, I2C, lecteur µSD ), piloté par un risc 32 bits et qui gère directement le Gcode .
