    Hello,
    I have been given 3 Robo 3d R1+ printers to try start a 3d print club at my school, these were in different stages of brokenness, one lap top to run them.
    I got two printers communicating with the PC, but the third says that it connected but there is no control from the PC. Using the same usb cable, and same usb port on the computer, created 3 different printer profiles, right now connecting one printer at a time. 2 are working fine and the third not!!
    Any suggestions?
    Thanks
    Erik

    What do you see in the GCode terminal from your host software when you are trying to control the printer?

    Here is the code I get, once it said it was connected I tried to use the Z+ button
    ->Communication State: AttemptingToConnect

    ->M105

    <-M105
    ->Communication State: Connected

    <-
    ->M115

    <-M115
    <-
    ->M114

    ->M105

    <-M114
    <-
    <-M105
    <-
    ->G91

    ->G1 Z10 F315

    <-G91
    <-
    <-G1 Z10 F315
    <-
    ->G90

    <-G90
    <-
    ->M105

    <-M105
    <-

    So if you send it a command via the terminal does it respond?

    try:

    G28;

    (uppercase letters since GCode is case-sensitive)

    Does it try to move the extruder any?

    Then the printer has bad electronics.
    Either the Arduino or the firmware loaded on it. You can reflash the firmware (see the FAQ link) and if that fails replace the arduino (and maybe the RAMPS, but start with the Arduino Mega) they are cheap.
