Hi
I'm building a Cnc router with dual gantry stepper motors, I can change design to belt drive to get gantry correction if needed but would prefer dual steppers for simplicity.

Can you recommend which controller to use, or direct me to a good link to help me choose.
Is there a common controller used by most?

I was planning on using Mach 3 as there is a big support group and lots of set up videos.
It don't have to be Mach 3 so any advise would be great.
I've read a few posts but as its all new to me I don't really know what features I'm looking for.

The only thing that is important to me is the support, so one that is well used in the community and I can get the help where needed.
Any information would be appreciated .
Regards Paul
