    Printing issues, I have a new issue that has started out of no where.

    My R1 does not appear to be raising z height during the prints.

    It goes through the autolevel procedure without any trouble and I can get it to raise z height with the software.

    But when I start a print the skirt and first level look too thin and when it goes to fill in the first level it is as if the nozzle is smashed to the print bed.

    No clue what has started this problem.

    Z offset? What do you have that set to in your startup GCode?

    is the fan on the bottom front right corner (when looking at the Robo lettering on your printer) running? (before you say yes....are you positive? :D )

    Here is what my startup GCode looks like.

    G28 X0 Y0 Z0 ; home all axes
    G1 Z5 F5000 ; lift nozzle
    M109 S[temperature] ; set the extruder temp and wait
    G28 X0 Y0 Z0 ; Home Z again in case there was filament on nozzle
    G29 ; probe the bed

    Your not defining a Z offset in your start up script? Should have a "M565 Z-1.0; set the offset for auto level" between the "G28 ;" and "G29". That -1.0 is default. You will need to play with that number over a few test prints to get your ideal first layer.
