The I opened and Repetier and - printer settings - connection - (two appear when usb connected) usbserial-1420 and wchusbserial1420.
but at the bottom it shows commands waiting and 1249FPS Unknown printer firmware... (but the number can change with every click -630,1291.1116,967.1338,1184)

Downloaded and installed Arduino 1.0.1 and 1.8.7 opened and ran.

If someone can advise how i connect Mac to printer... then which correct software and in order of loading and what I should expect to see on the green LCD... I then still have to calibrate and print something.

is this suitable for iPhone? I am facing lots of issue after updating the firmware on my device. I want to avoid iTunes error 9. If you have any idea about it please inform us.
