    I had to cancel a print.
    when I started the next print the printer started from the middle of the bed.

    I tried the home all button . didnt help.
    this has happened before and thought home was at the opposite side of the bed.

    I closed the program and restarted but it isnt helping this time.... so far.

    HOME is the only position that is certain (since it has physical switches).
    If your printer is not homing then the switches are not triggering correctly.
    • one or more switches has a problem
    • wires to switch has a problem
    • connection to RAMPS has a problem
    or... your software has lost its mind and is ignoring the HOME :)

    The last one you an confirm my using the GCode console/terminal and entering the HOME yourself and see what happens.
    Send it a G28 for HOME ALL:


    G28 X0 Y0 Z0 ;

    or

    G28 ;

    after printing a job I clicked home all button in matter slice.
    took me close to where I normally start from.
    released the motors and manullay moved the bed closer to where it normally starts from .
    clicked the home all buttonand it worked.

    I also entered the g28
    g28 took me to the middle of the bed
