Planning to wire my grbl programmed UNO to some stepper drivers and they (the drivers) want to know
if it (the Arduino) is common anode or common cathode. Not terms I am familiar with, the wiring is definitely
different for each.
Any info appreciated.

How did the stepper drivers tell you that?

There is a whole slew of "different" drivers out there.
A direct link to the EXACT ones you want to use is the least you could give anyone along with the steppers you want to use.
Could you also take a few moments to Learn How To Use The Forum as it seems you missed those posts.
Other general help and troubleshooting advice can be found here.
It will help you get the best out of the forum in the future.
The OP may be referring to stepper drivers like the TB6600 that have opto-isolated step, dir and enable inputs. Those inputs can have the opto anodes tied to Vcc and the cathodes controlled or the cathodes tied to ground and the anodes controlled. Having never used those drivers, I do not know the advantage of one over the other (if there is one).

Common anode usually refers to the situation where the positive side is common and the negative is switched. Common cathode would be the opposite.
As others have said a link to the datasheet for your stepper drivers is essential.
