electronic gearbox with 7i76E was created by fons
it is not a real cnc problem but i think is also about cnc
for an agruculture project ( corn sawing machien ) i need to control 8 motor who run at a controled speed comparing the speed of the traktor
shaft enconder on the wheel of the traktor one pulse each cm and on the seed injektor i have 60 pulse for each seed
the problem is every 10 cm i like to shoot 1 seed so for every 1 puls of the traktor the motor of the seedinjektor had to turn 60 pulses
i try to solve this problem with an aduino with a dc powerd motor with an ibt2 pwm module
it dont work i lost to many pulses and the rotation speed of de cd motor wasn't stable
i try it also with a isp32 and a PI 4b al with the same resultat
do someone try these before ?

Hello,
Couldn't you get Arduino to output 60 or whatever you want when it gets a pulse? And send the whole thing to a stepper motor. In this case you don't need a directional signal.

@fons,
You just posted again the same question with the same subject, this is the second warning.
The other topic deleted, again.

As for your question, it is to convoluted, try drawing a diagram, or take some pictures, or try explaining thing line by line as they are supposed to happen.

All we can understand from that is one seed must go after 60 pulses, that should be 10 cm but you say 1 pulse for 1cm, so that does not add up.shaft enconder on the wheel of the traktor one pulse each cm and on the seed injektor i have 60 pulse for each seed
the problem is every 10 cm i like to shoot 1 seed so for every 1 puls of the traktor the motor of the seedinjektor had to turn 60 pulses
