OK, after seeing Adamfilip's awesome HulkXY machine I am very jealous of the quick z-ais lift speed he has achieved. I was wondering if anyone knows why the iv3 has such a slow z-axis lift, and if it is possible/easy to change it?

I assume I can either change the speed/acceleration profiles within the Marlin control panel, or maybe even the code. Failing that, perhaps we can back off the microstepping on the z motors a bit to achieve more speed and torque?

I'm hoping that a faster z-axis lift will result in slightly quicker print times and less blobbing at the lift location.
