Small steps,...in the fog...?

[cloudbase]

Hi All..
Ok...I've been procrastinating about this for too long, and have decided to jump in with hands and feet tied, bag over head...so if any kind soul wishes to rescue me...feel free..
Just way too much to injest, but for me, making the table at least shouldn't be rocket science with all the info available.
The intent is to put together a home hobby, moving gantry table, about 25" x 36", to mill wood, plastics,...and just maybe light allum, small items.
So...first of many questions...
What is the most important axis to consider a motor(s) for...? iow, is there an axis that generally requires a little more 'oomph' than the others.
There seems to be a lot of '3' motor deals out there.
Thanx for any response
Cheers

Most use two motors to move the gantry, but they typically use the same size motors for al the axis.
