How do I go about configuring an U axis to drive in tandem with the X axis.
Is it a true U axis, or a second motor on the X axis?
The trivial answer to your question is that to make the U axis move in tandem with X, you use G-code like G1 X10 U10.
However, that is such a trivial answer that I suspect that isn't really your question.
I am guessing that you have a gantry machine with two motors on one axis? There are two ways to control that, depending on whether you want a separate home switch for each side to give you auto-squaring or not.

To answer Andy's question, a gantry router with two motors driving the x axis preferably not slaved so the motors can be tuned separately for homing, backlash etc.

In that case, Gantrykins is probably the answer.
There is a gantry config in the sample configs, but it isn't terribly friendly (it needs work even to get it off the limit switches, for example).
I think Seb created a more friendly sim version, but it isn't in the released version yet.

I have have copied the files for gantry but don't know how to upgrade to 2.5 I have 2.4.3. I tried making a new CD but come up with the problem of having a file "etc/apt/sources.list.d" and no "/emc2-buildbot.list:" extension. do I simply add a folder and name it that, create a document of that name or is it an executable file i need to import.
Thanks again

You don't need 2.5 to run that configuration.
Just put all those files in a folder in your home/emc2/configs/ directory (for example, in home/emc2/configs/gantry ) and you should be able to start it from the menu
