redoxcode / micropython-stepper Goto Github PK

Hi,
It is said in your read me that this lib allows the user to command several steppers in a non blocking way.
I understand here that 2 steppers can be driven independantly at the same time.

I tried a simple wiring, with 2 stepper using 2 TMC2209drivers. with the code under this issue. I tried to disconnect motors 1 after the other to test it alone and everything is going well, it does 180° in one direction then comes back to 0°. But when I plug both motors, only one is moving.
The non moving stepper is plugged to a driver that seems to have a default (high urrent consumption when the motor isn't enabled). However, this particular driver is moving when I command it alone.

Do you have an idea of what would cause this behavior ?

thanks,
Sylvain

My program :

from stepper import Stepper
import time
from machine import Pin

Pin(5, Pin.OUT).off()
Pin(21, Pin.OUT).off()


s1 = Stepper(18,19,steps_per_rev=200*8, speed_sps=500, en_pin=21, timer_id=-1)
s2 = Stepper(22,23,steps_per_rev=200*8, speed_sps=500, en_pin=5, timer_id=-1)

s1.target_deg(0)
s2.target_deg(0)
print(1)
time.sleep(3.0)
s1.target_deg(180)
s2.target_deg(180)
time.sleep(3.0)
print(2)
s1.target_deg(0)
s2.target_deg(0)

Add an easy way to check if the final position is reached.
Maybe a function to return the difference between target and current position?
Maybe just a function that returns a boolean?

Why MICROPYTHON STEPPER ON ESP32:
GPIO27 AND GPIO14 CAN'T BE USED?
