Is it silly to ask you whether the driver in mounted onto a heatsink ?
Hi i am new to this forum but saw posting about TB6600 stepper driver i cant get motors so run and looking at schematic all the power supplies seem to be at the same ground and i have isolated 5 volts and 24 volts stepper power supplies ... should they all ground together?
Grateful for any help
