Moving gantry and table on the same axis - why not?

[JAZZCNC]

This has been done before with Mach3. It's not massively complex but does require some special coding or formula's to be created I think.
I'll see if I can find a link to a thread of someone who's done it.

This is one way but I've seen better way using formulas in mach3 just cannot find it yet, but I will.

If you design both drive systems to use a similar number of steps for full travel, just slave them, and adjust the steps per mm/inch to suit.

Great - it's not a crazy idea!

I need to research whether gearing, formulas or 'slaving' is the way to go as well as how much cost/complexity it will add. As if learning the basics wasn't mind-boggling enough...

Thanks all.
