Pessoal, alguém poderia me dar uma luz.

Construi uma CNC controlada com Arduino, ela funciona OK durante o Corte, mas em qualquer
botão manual na orelha "Machine Control" do "Universal Gcode Sender"
ela não obedece, o motor faz barulho mas não se move.

Parâmetros:

**** Connected to COM3 @ 9600 baud ****

Obrigadão pessoal.

Abraços

Se resolveu, está bom.
Esse sistema que vc usa não é muito comum aqui no fórum. Talvez, por isso, o pessoal não tenha dado pitacos.
Abraço.
Jorge

Coloquei o parâmetro 8 em 1

Abraços.

Voce está utilizando a versão mais antiga do GRBL,a mais atual é a (grbl_v0_9j_atmega32 8p_16mhz_115200.hex )
Com essa voce tem mais opções de controles tipo PROBE,HOME,start spindle.
Segue a minha configuraçao.
