Posted this in the RepRap group as well so I can try and reach the most people for help.
I have a ramps 1.4 board in my custom A8 with a capacitive sensor, everything has been working fine over the last few months, but recently everytime I level my bed the z distance seems to change. I'd go from being at -1.90~ to up to -2.5 and randomly in between. Not sure if my sensor (or capacitive sensors in general being considered inconsistent) has gone bad. but it's really frustrating. If anything i'll probably end up getting a BL touch or something else for auto level solutions if it comes down to it.
