ESP32 Wemos D1 R32 + CNC Shield V3, motors not responding in python

Support and Help Desk
1

Current setup is a wemos D1 R32 with a CNC shield v3. As described in GitHub - openUC2/UC2-REST: UC2 code for using the REST API with electronic modules (LED, motors, etc.). I removed the resistor and power the board using an extra wire as described in the youtube video. I am flashing the board using the online tool and using PlatformIO following this tutorial:
UC2-ESP Firmware for the openUC2 UC2e electronics | openUC2 Documentation

In the pinconfig I changed the last line to: const UC2_WEMOS pinConfig;
Flashing seems to work since it I get the ‘hard resetting’. In python if I connect it gives the exact same output (Using API Version 2 etc.) as it would with a UC2 board. In the _state it does nicely state: pindef: UC2_WEMOS. But If I sent any commands such as ESP32.motor.move_x(steps=10000, speed=10000, is_blocking=True), it does not move. The motor is the NEMA motor also used in the motorized Z-stages.

Using the code given here:

The motor moves normally and it works. The pins are the same as in the WEMOS Pinconfig. I measured the voltage on the boards and that is as expected.

What am I missing?

Thanks @tomvh for reporting this. What’s your python script you’re using if I may ask? How did you install UC2-REST (Python)? Can you check if the following website enables you to run the motors? openUC2 WebSERIAL Demonstration

Thanks for the prompt reply! I think I have an idea. So I tried the webserial demonstration and nothing happened either. But once I pressed auto enable the motor works. Also after pressing auto enable off. Once I power everything and from the webserial demonstration enable Auto Enable, in python it also works. So in my python code I now also sent the auto enable command and then it works.

for testing this is my code:
#Import necessary libraries

import uc2rest as uc2
import numpy as np
import time

serialport = “COM4” # for Windows - change accordingly
if ‘ESP32’ not in locals():
ESP32 = uc2.UC2Client(serialport=serialport)
_state = ESP32.state.get_state()
print(_state)

auto_motor = ‘{“task”:“/motor_act”, “isen”:1, “isenauto”:1}’
ESP32.serial.writeSerial(auto_motor)

ESP32.motor.move_x(steps=-1000, speed=1000, is_blocking=True)
ESP32.motor.move_x(steps=1000, speed=1000, is_blocking=True)

I used this command to install uc2-rest: pip install UC2-REST=0.2.0.15 --user
