Hello my friends, I want to connect the Mach3 board with the CNC Shield A4988, what is the method? Please help me as the obstacle was the difference in the names of the ports so I need help with that or someone who has the connection diagram Thank you
This call for help might need more information like links to the two particular products you purchased.
As Greg says it may be different between different Mach3 boards. I found this
which would suggest it just a case of connecting the STEP and DIR pins of the A4988 to PUL+ and DIR+ outputs on that controller board respectively (also connect all the common grounds)
