Hey Guys,
I'm using a CNC Shield V3 for the Arduino with GRBL and it works perfectly.
I am now trying to add END STOPS / Limit Switched. I have Normally open loop and they work fine when the stepper motors aren't powered on but as soon as i power on the stepper motors it suddenly trips the alarm and says the end stop has been pressed even though it hasn't.
If the motors aren't powered on then the end stops work fine when i press it then the alarm get's triggered otherwise it doesn't. Anyone have trouble like this?
