Hi,
I have completed my build and have powered up. Fans are running and LED is lit with message "Pi3 Pro X ready." I am finding the instructions confusing (sorry) for downloading software needed to run the printer. So far I have downloaded the FTDIUSBSerialDriver_v2_3, Repetier-Host Mac and Arduino. Not quite sure what to do with these though? I have the GT2560 + 4 A4988. Not sure what to do from this point?
Thanks

The repetier host is used to control the printer. And the arduino is used to upload the firmware to the board if you want to change some settings, like the wrong direction of motors or others things.
Check out the link here, you can learn how to use repetier with your MAC:

you can refer to the link here to install the firmware:

and if you want to download the firmware, find the one for your printer here:

Also if you run into those common problems like wrong direction of motors, hotbed not heating up or something else, you can check it here first:
