Things get ugly when I press "home" on an axis in Repsnapper. The printer seems to want to drive the axis off the Prusa! I'm a little reluctant to try the home feature again unless I'm confident I can get it to work safely.
I try "G92 Y0" to reset the relative position of Y, and M114 to confirm the input, but when I press "home" for Y the printer seems to attempt to travel infinitely down the negative Y axis. Any ideas what I'm doing wrong? Where exactly is "home", and can the user set it?
Finally, will the printer automatically know how to move a given number of inches/millimetres, or will its estimates be unreliable without further calibration?
Thanks!
