Dear all,
my question is about how to realize a syncronous movement of 2 stepper motor (one move in X direction and one move in Y direction), controlling by 2 l6470 connected in a daisy chain configuration also with STM32F4DIS-EXT.
In particular I would know if in this configuration's type there is a delay in sending the input command between the 2 motors, and which is the smartest way to obtain straight trajectories (i.e. have a simultaneous movement of both motors at the same speed)
Actually I using commands:
after calculation of the step that I want to realize with the 2 motors
Thanks in advance
Best regards
