Sorry to hear that you are having issues. For what it is worth I am using AstroPrint and my prints and workflow of prints is much easier to manage. But still learning G-Codes and also making sure I use the REPRAP/Marlin all the way from Cura to Slicing in Astro (if I needed).
For what it is worth, I'd firstly connect the Printer Via usb to a PC, Open Cura and push a firmware update. Then print a SD based job. Maybe even copy an existing job from Astro to the SD and try. Then go back to your topology and try..
Hope all or some of this helps.
Hi and welcome
I don't know about Astro print but it's probably the same.
For Octoprint you need to change the gcode flavor, from UltiGcode to reprap, when you change this you have two new tabs that will appear in Cura start.gcode and end.gcode, these are called at the beggining of the print and the end (obviously), and it's the place where you can set up proper priming etc...
