Running this on a Taz 6 with a Titan Aero head
I got a RunTime Error on importing an 87mb file. Down resed to 3.5mb worked fine.
In the Manual Control Panel, If you could retain Move Lenght and Extrusion amount.
A separate tab for Extruder temp and bed temp would help.
Also to have an override for print speed would be nice
The issue that I was having with stalling has gone away with updating to 2.6.38
