if you wanna mess around with the usercommand file (i recommend it over using axis.py or axis.tcl if you can avoid it) , here is some sample code I use for my touch screen endeavors, but my screen is much smaller at 800x480, but the ideas are the same, bigger scrolls, sliders and buttons
########### BUTTONS ###########
#estop button
W(".toolbar.machine_estop","configure"
