Assistance on 4th axes setup

[toad]

Wayne #25

I am trying to get a 4th axes setup, Presently I have as described,
A axes slaved to B
Set up A axes,
A and B enabled (Why B?) step 2 port 2
Toolpath
Axes of rotation
X checked
A rotation enabled checked
Show lathe objects checked
What am I missing? What on the keyboard jogs A axes?
Good info, but I am still lost. Can you anyone else assist further.
Where can I find more info.

Why is A slaved to B - Its usually X slaved to A
Why are you using port 2, do you have two ports and two BOB's, if not, they should be set to: step1, port1

X-Axis is usually down the length of the machine and if you have two motors then another axis is slaved to it (a 3 axis machine would slave A, on a four axis machine I would slave B - On the general logic config tab, uncheck "B axis is angular")
Y-Axis is usually across the width of the machine.
Z-Axis is vertical from the table
A-Axis is usually rotational on its own

These settings also need to correspond to the correct settings on the ports and pins - motor outputs tab.

Alan,
Thanks, I was mainly going by what wayne had set up. H must have 2 bobs.
I was having a hard tim getting my arms arouns B also and port 2.
So there is no key to move A, does everything else look ok?

Thanks
