Thank you for the info Adrian!
So you keep the driver board. What does that mean for the performance? is it more on the slow side? And what about the precision? Do you know how many steps are to a millimeter? half step? quarter step?
I used the planet cnc in the past and wasn´t very happy so I would like to stick with Eding if possible and today I found a Boxford mill on Ebay using the Eding controller. Looks like it is possible the only thing is how to do it.
How do you tell the ATC to react, when changing tools?
How many hours would you think I have to invest to rewire it all?

Regards
