Hi,
Also have homing switches on all axis
How exactly do you mean?.
On the master/slave axis do you have a home switch for each motor OR do you have one switch for both?
It makes a difference. When a motor is homed it will drive to its home switch, whether it be a master or slave.
If a motor does not have a home switch assigned to it, it won't move and will just 'home in place'
Could it be this is what is happening? Does the slave motor (motor 3) have a home switch assigned?
There are two reasonable solutions to this. You could have two separate switches at each end of the gantry.
In this case you would have two inputs, one being the home switch for motor 0 and the other being the home switch for
motor 3.
The other way is just to have one home switch on the gantry and both motors share it. I have attached a pic of
how that would look on the Control/Input Signals page. Note that both motor 0 home AND motor 3 home are enabled
but they point to the one input pin, port2 pin10 in my example. That is so say that both are enabled but they monitor
just the one switch.
Clear as mud?
