    Title says it all. There is no switch to limit +X travel, so it can make some horrid noise when beating against the stop.

    I imagine one could be added and spliced to the existing wiring. Not sure if that would upset firmware, etc.

    This style of printer does not use MAX axis switches, only MIN axis switches (HOME). So you have to define that limit in the firmware and it will keep track of it.

    Ah. Then dullards such as myself need define those limits in our own :"some-ware" I guess.

    It is defined in the firmware source. You can download the source for the R1 series from Robo and look in CONFIGURATION.H (all in MM IIRC)

    Here is an example from an R1:

    // Travel limits after homing
    #define X_MAX_POS 240
    #define X_MIN_POS 0
    #define Y_MAX_POS 254
    #define Y_MIN_POS 0
    #define Z_MAX_POS 240
    #define Z_MIN_POS 0
    #define X_MAX_LENGTH (X_MAX_POS - X_MIN_POS)
    #define Y_MAX_LENGTH (Y_MAX_POS - Y_MIN_POS)
    #define Z_MAX_LENGTH (Z_MAX_POS - Z_MIN_POS)

    All of the (or nearly all of the) configuration details specific to your printer hardware ... are in CONFIGURATION.H
    So that is the Go-To spot for making hardware related tweaks.
