I have a Reprappro Mendel with a dual x carriage running on a megatronics v3 board, I've just tried implementing Auto Bed Leveling and I'm seeing some strange behavior.
When I try a G28 it homes and leaves X & Y in the Z homing position, but when I try and move an axis from Pronterface X,Y & Z move at the same time until X & Y have gone back to there home positions. It then moves the selected axis as commanded! The only way round it is to call T1 and then go back to T0 after homing, but then G29 seems to exhibit similar behavior.
Can anyone help me shed some light on this one?
