I’m planning to add a powerfeed to my mini mill by using one little NEMA 17 drived by and Arduino and one of you DRV8825 drivers.
The idea is to have a couple of gear and a toothed belt drive connected to the hand weel of the axis, so I can still use the mill in manual mode.
Talking with some guy they told me to always disconnect the motor from the driver as the current generated by the motor turned by hand could destroy the driver itself.
I’m not good at electronic so I prefer to ask to who made this driver.
Is that true ?
Can be avoided in some way, in case it is true ? Eventually adding some more components on the driver side ?
Thanks in advance.
