Lotmaxx dual extruder

Posted · 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.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
