Hi,
now the last thing is to set the Homing&SoftLimits tab of the Control plugin.
This is where some confusion may arise. Note down the lefthand column you see X,Y,Z,A etc....in fact the axis letters are a red herring, the real point is the numbers, 0,1,2,3 etc
corresponding to the motor numbers. Note the the Z axis Homes first followed by the Z axis, but motor1 and motor 3 Home simultaneously, and motor1 is the Y axis master and
motor3 is the Y axis slave. That they should Home together is 100% correct. But note that they are quasi independent, that is motor1 will Home to its moror1-Home switch
and motor3 will Home to its motor3_Home switch. If the switches are set square then the gantry will end up square also, even if it started a bit askew.
