I just recently got my AR4 MK2 kit and am starting the build. Still a newbie to all this but it got me wondering... Is the current firmware/software capable of constant velocity coupled moves? Especially since there is the new option to feed it 3 axis (maybe more axis? Couldn't tell yet) gcode. Would be cool if I could throw a filament extruder on there and make it print. But will definitely need constant velocity.
