When I use Repetier Host manual control to zero all axis, I get Z=326, X=-135, Y=-135. If I advance the head from the stop position by using the positional control to advance say 50mm down and then say X + 50mm, the display will now show X=-85mm. Trying to move minus 50mm from the center position will result in no move. The Y axis behaves the same.
If I home all axis and then move down using say G0 Z0, the moment I give a required position on X or Y, say "G0 X0", the display changes from -135 to 0 and the manual controls can now be used to move to minus positions
I think that the printer will now print, but where does the -135 come from? Is it best to just live with it or can it cause problems?
Further info: More or less standard Rostock printer with Ramps 1.4, Repetier-Firmware-Development downloaded and installed yesterday, previous Arduino sketch lost with disk crash a few months ago so all settings are my best interpretation.
Thanks for any help,
Mike
