Cannot connect printer
I recently bought my first 3d printer, a delta k200. I assembled it correctly turned on the lcd and it started up and the lcd screen on the printer said "printer is ready". Then i downloaded the repetier software on a mac os and tried connecting the printer. I got the baud rate right 115200 but i can not find the com option (for connecting printers i think) I hook up the usb cable (included in the box) from the printer to the computer and nothing happens. What do i do?
