IDEX Help - Nozzle collides with model


Recommended Posts

Posted · IDEX Help - Nozzle collides with model

Hi all,

Here is the situation. I've added a dual carriage and all of the associated things (extruder, hot end, end stops) to a CR10 V2 using a BTT octopus 1.1 board. Currently using Marlin Bugfix 2.1.x. and a custom Cura printer in Cura 5.3

Here is the scenario. In Autopark mode, when I switch from T1 (right carriage) to T0 (left carriage) the following occurs:

  1. The Z axis raises 2mm
  2. T1 goes to its park spot (x=312)
  3. T0 goes to the location T1 just left
  4. T0 gets to temp (if not already)
  5. Z Axis lowers to printing level 2mm
  6. T0 moves to next printing spot


Because the slicer (Cura 5.3) creates gcode with T0 completing layer1 then T1 comes in does its layer 1 then layer 2. Then T0 comes back and does its layer 2. Steps 3 and 5 above cause the nozzle of T0 to crash into the model because T1 has already completed its layer 2.

Fun build and generally have everything working except for this annoying problem. This may be a thing I can fix in my slicer or maybe a marlin setting... Just not sure where to go from here. Any help would be greatly appreciated.

      • 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.
