Lotmaxx dual extruder

I have a lotmaxx dual extruder.  When I print and it needs to switch colors it stays over the print  so sometimes it oozes on top of the print.  I enable prime tower and ooze shield.  Is there a way or setting in cura to get it to retract and move to the prime tower while it is switching colors instead of staying on top of the print.

    I don't actually have a dual extruder printer.

    I do have a virtual dual extruder printer that I configure for questions like this so I can learn.  That means this MIGHT work for you.

     

    It appears your printer is a 2-in-1-out so you may be able to configure it using 2 Search and Replace post-processing plugins.  The search and replace script allows newline characters "\n" so it is possible to insert multiple lines.  That's the trick.

     

    This example assumes the prime tower to be at X175 Y175 and travel speed at 7200mm/min (120mm/sec).

     

    In one instance of Search and Replace set the search box to "T0" and the replace box to "T0\nG0 F7200 X175 Y175".

    In the 2nd instance of Search and Replace set the search box to "T1" and the replace box to "T1\nG0 F7200 X175 Y175".

     

    At each tool switch the code should look something like this:

    T1
    G1 F7200 X175 Y175
    G92 E0
    M106 S170
    G1 F1200 E15
    G1 F600 Z0.6
    ;MESH:25x25Cube.stl(1)
    G0 F7200 X163.754 Y189.83
    G0 X163.242 Y188.11
    ;TYPE:PRIME-TOWER
    G1 F1500 E20

    The initial tool switch would look the same.  It shouldn't make a difference but you should check it to make sure.

     

    You may be able to accomplish the same thing by adding the movement line to the Start Gcode for each extruder.  In that case it could use keywords "G0 F7200 X{prime_tower_position_x} Y{prime_tower_position_y}" which isn't possible with a post-processor.  In that case there is a subtle difference:

    T1
    G92 E0
    G0 F7200 X175 Y175
    M106 S170
    G1 F1200 E15
    G1 F600 Z0.6
    ;MESH:25x25Cube.stl(1)
    G0 F7200 X163.754 Y189.83
    G0 X163.242 Y188.11
    ;TYPE:PRIME-TOWER
    G1 F1500 E20

     

    If the machine is a conventional 2-in-2-out dual nozzle then the above might not work unless the "Cool Down" and "Heat Up" times and the "Standby Temperature" were played with(?).  I haven't looked into it that far.
