Hi all pro,
I am a new comer in CNC. Pls help me with this issue
I am trying to connect 3pcs of TB6600 to 1 Mega 2560 as photo and using the GRBL firmware. (1.1)
https://images.app.goo.gl/p37FCyh5YAFbFtjV6
(sorry that I am using phone, I cant change photo to jpg or gif to upload it)
The confuse is that there is only 1 Stepper EN pin in the diagram and only 1 stepper En Pin is defined in the grbl code as followed (cpu_map.h)
#define STEPPER_DISABLE_BIT 7 // Mega2560 Digital pin 13.
Do I just ignore other 2 EN Pin of 2 remaining TB6600?
Thanks
