U axis configuration

How do I go about configuring an U axis to drive in tandem with the X axis.

Have you looked here for some ideas?

Thanks Rick I went right past the gantry router which I used with the g540 three axis version of my gantry router and started messing with modifying a 5 axis ie. six axis set up. As can be imagined I got into all sorts of trouble, so will revisit the gantry set up thanks.

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.

PS. I really wouldn't want to have to write it into the G-code

Thanks for that, I haven't got round to it yet but will certainly give it a go.

Sorry this may seem a silly question but I am very new to Linux, I had a problem with Mac3 I found EMC2 made a CD did an xyz Gecko 540 stepper config wizard and away I went I was most impressed. So Impressed I decided after running a G code file of about five thousand lines and two hours running that my home made gantry router had to be re built and up specked.

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
