Hi,
I am setting up Marlin on my RAMPS 1.4 set-up and I try to read a lot about it. I have off board upgraded drivers (NEMA 23 motors) which can handle a lot smaller microsteps than 1/16th. Also I am looking into adding presicion with 0.9 degree stepper motors and I would like to speed things up once I have it printing decently. All this will ask a lot of the processing speed of the Arduino Mega. Now I stumbled across the chipKIT Max32 :

This caught my eye:
![chip-kit-max-tab.jpg]( "chip-kit-max-tab.jpg")
Would switching that for the regular Mega give me the computing speed I need for more steps and more speed? Or is Marlin / Arduino aware of the Mega's limitations and won't it allow us to use it at a higher speed that what the Mega can handle?
Cheers,
Hugo
