New to Cura - Problem getting the UM2 to recognize print bed

[AlmondPA 1]

I am new to Cura and when I tried my first print the print head just started to print in the air. I am using the most current version and use an iMac with my UM2. What can I do to use Cura to print? Currently have to use MatterControl

In cura make sure you go to machine settings and put it in "rep rap" mode. If you print over usb (which isn't officially supported) then you have to have the gcodes in reprap mode.

The basic difference between reprap and utligcode modes is that in ultigcode mode the file does not do the basic startup sequence like setting heat homing and priming and also all the extruder moves are in cubic mm instead of linear mm. The advantage of ultigcode mode is you can choose the material after slicing and affect things like fan, bed temp, nozzle temp based on printer settings instead of cura settings. If you are in reprap mode, more parameters appear in cura including bed temp and nozzle temp.

then save the gcode file and print it with mattercontrol.

Thank you gr5 for the response. I will try that once this print finishes.
