    Hello Dan,
    nice softs…
    I have made a few modifications to your CNCDemo4AxisRAMPS for a stand alone CNC :
    – added an SD card reader (number of total lines in the file, then executes line by line) ,
    – added arcs ,
    – made the feedrate (F1 to F200) working,
    – corrected int i, segments.
    (Todo : made the endstops and an Estop working )
    It works with a MEGA and RAMPS and drivers DRV8825 and NEMA17
    or without the RAMPS and with µStepper drivers and NEMA23.
    With lead screws of different pitch.
    Temporary name of this sketch : CNCDemo4AxisRAMPS_SD .

    Can you have a look on my sketch ( the SD is in a tab) and in the hope that it will interest people how can I share this soft?
    Best regards,

    Hello Dan,

    I tried to send a pull request through github but it seems that it concerns the changes to 1 code.
    ( the SD card is added to a mix of 2 of your codes… )

    Always in the idea of a stand alone machine I have added since Xmas a read and save of (4) Gcode names of files on the SD card.
    While adding an Oled128x64 ( an LCD2004 is big and current hungry) and a joystick it will be possible to choose the file to run and display the “line of total lines” processed .
    I’ll get back when it is done.
    Best regards,
