标签: help wanted

When i change the ‘step idle delay’ to 255. stepper motors locked. It’s ok. But when i change it back to 25. stepper motors still locked. The step singal allways high.

My firmware version is 1.3a

I think they will unlock after the next move.

If you want to unlock them temporarily use $MD

Thanks for your reply. I have tried many times but problem still even though erase full flash and reflash esp32. Maybe my board causing. I will check it. Thx.

I would assume you have a hardware or machine definition problem. Nobody has reported an issues with stepper enable.

What hardware are you using. Are you 100% sure the pin is connected properly?

Try this.

Set $stepper/IdleTime=200
Reboot the ESP32
Check the voltage of GPIONUM12
Do a long move while checking the voltage of 12

GPIO12 is a special pin https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection
Have you tried GPIO13 ? the examples use also this pin.

resolved by latest code on devt branch.
