GSK988TD Dual Channel CNC User:

Hi,  the S500 M3 is working properly under MDI mode for S1-1, but S500 M63 is not working, M63 no responding. 

CNCmakers Support:

It could be mess with the four analog voltage, so please work the first spindle of first channel out first, then one by one to set others.

Please set S2-1, S1-2 and S2-2 to 0, then set S1-1 as -1, -2, -3, -4, and then execute M3 S500,

Please delete the symbo ; on the second line, move the cursor to first line, and then press the cycle start to execute M3 S500
