Still working on getting my printer off of the ground. Most everything is working (yay!) but I'm having some weird issues with my endstop.
First of all, I wired the C contact on the momentary switch to GROUND and the NC contact to S. When I open Pronterface and send M119, I always get z_min:L regardless of where the print bed is. Now when I send the print bed up and hit the endstop while it's moving upward, nothing happens. When I send it down and hit the endstop while it's moving, Pronterface says "endstop hit: Z:" and wherever it registers the bed to be located. It seems to me that all I should have to do is change a setting in the firmware to flip the Z axis so that the endstop operates as it should. Am I on the right track?
Also, when using Pronterface, whenever I hit any of the HOME buttons, the printer either doesn't respond at all or it tries to send the print bed down as far as it can go until I unplug the printer. I always unplug it because I'm afraid it will smack right into the RAMPS board if I don't. Any thoughts?
Thanks for your help everyone.
