Hello, I'm using a clone Kossel mini with Repetier firmware. I'm working on bed leveling and my issue is that my hot end travels on an angle across the bed along the X axis, Y axis is okay, as opposed to having a concave or convex motion. So on one side of the bed, ie, X=-50, Y=0, the hot end is say 2mm above the bed, and at X=50, Y=0, the hot end starts to dig into the bed. I was able to work around this by manually setting the endstop offset using the "paper test" and changing the printer radius in config.h file. But my prints are still a little off. For example, when I print a test cube, the finished cube is leaning a little to right (when printing it leans toward the positive X axis). I have a capacitive sensor as my Z probe, but haven't had much luck using it for bed leveling. Should I be changing the "printer radius" and "rod radius" to correct this? Any ideas why this is happening?<br id="null">Thanks, Jim G
