Powering off the stepper motor while spindle is turning #261
Comments
If you turn off the controller using the power button on the far left it should release the enable line on the stepper driver and the motor shouldn't run. |
That only works when the spindle is not rotating. |
I guess we could ignore the fact you could have turned off the ELS before you started the spindle... ;) In UserInterface.cpp the power toggle occurs after the test for the spindle rotating. I've obviously not tested this to see if there are any unintended consequences. Failing that just fit a switch to the enable line. |
Thank you. I burnt a ti board a while back due to over voltage on the input by mistake and don't want to buy a third one🤣 |
Nope, all that will happen is the motor will stop dead. (Be a lot easier just to tweak the software though). |
Hi,
Most of the time I don't want the stepper motor to turn. It's just noisy. It's annoying to turn off the lathe just to power down the stepper motor.
As I understood the idea behind locking the PWR button is electrical interference safety issue - which I have not encountered even in the first release.
Could summer assist me with enabling it out alternatively add a physical power button that would deactivate the stepper motor regardless if the spindle is turning or not without burning anything on the electronic boards or stepper motor.
🙏
