I’ve seen some similar topics but I wanted to open a new thread in order to have everything summed up in one location.
I only set up the minimum end stops in order to make a homing sequence, which is very important especially for taking and releasing the tools.
To wire your end stops you have to plug the Signal to the NC on the switch and the ground to the C on the switch. If the “Find home” on any axis is not working try to click on “Invert end stops” and see if it works. If it’s still not working, check your wiring and if OK then change the switch in case it might be broken.
You can find where the signal and Ground pins are on your RAMPS in the following link:
My problem comes when I try to set a “find home” sequence. The farmbot starts running backwards on the defined axis until it triggers the switch and then stops and sets its position to 0. If then I try to go to another position, let’s say 100 mm, the farmbot says that the movement is completed but doesn’t move since the switch is still activated. Therefore I have to deactivate the end stop, move to the desired position and then reactivate the end stop. Is there something I have to change to allow the farmbot to move even if the switch is activated? Or maybe a way to say, once you trigger the switch move 10 steps and set 0?
Thanks for your support guys!
