Hello
I will appreciate any help here.
I have a laser engraver running on an Eleksmaker Mana SE controller board with a4988 drivers.
Y axis has 2 nema17 steppers running off the same stepper driver.
Wanted a 3rd axis for rotary, so I got an Arduino nano with cnc shield v4 with a4988, and got it working.
But this will not drive the 2 steppers on the same driver - driving one stepper is perfect, but with two steppers it just hums a bit, only moving the axis if i gently push it.
any advice?
