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:motor_Go_To_M1motor_Go_To_M2after calculation of the step that I want to realize with the 2 motorsThanks in advanceBest regardsMarco Cingolani2014-06-16 04:27 AM
I have a very similar requirement, except that I also need to be able to change the speeds of the two drives synchronously (and without stopping), so that the x-y motion can define (say) a circle.
The two possibilities seem to beThanks, Phil Atkin
