Driving two stepper motors at the same time

[tenaja]

The easiest way is with interrupts and two timers. Set up one timer to control x, and the other for y. You calculate the timer preset values based on the delay between pulses.

With an 18F you can even do it with low and high priority interrupts... you just use the low priority on the axis that will be going the slowest. If you won't know, then pick any one for low priority, or use one high priority interrupt with a test to see which timer rolled over.

Hi,

If it is for diagonal moves only ...

same clock signal for both motor drivers and just invert or not rotation ...

if direct drive ...

just can be solved by twisting 1 st motor signals ...

only logics with bits ...
