Cura ignoring gcode variables

Posted · Cura ignoring gcode variables

I'm trying to use Cura 4.11 with my Lulzbot Taz 6.   I can't even really get started though because the starter code uses gcode variables that Cura apparently ignores now. For my start gcode, I have :

 

 

M109 R{material_wipe_temperature} ; wait for extruder to reach wiping temp

Which should replace the variable with the extruder temp as below:

M109 R140 ; wait for extruder to reach wiping temp

 

But it doesn't... It just prints exactly that line, curly brackets and all in my final gcode.   There are several other areas where variables are used and they are all ignored.

 

Is there a special setting I should turn on somewhere? Were these variables removed at some point? I can't imagine why they would have as they are really useful.

    I cannot really help you with your specific question, but Lulzbot has/had their own modified Cura version, which is different from the official UM version.

    I've been using that version for a while. To be honest, I don't like it as much for some reason. Maybe I'm not experienced enough, but I feel like I'm missing out on some plugins that I had already learned to use before I got my Taz 6.   I had previously had a prusa i3 clone that I added dual extruders and other tweaks to. With the Taz 6, I'd like to add my own dual extruders as well, but I feel like I have less control over configuration options with the Lulzbot edition of cura.  Technically lulzbot is open source, but even for someone who codes a lot on both computers and embedded systems, there's just sooo much code to digest before I'd be able to tell what the customizations are in their version.

    As far as I can see, the material_wipe_temperature setting is not available in Ultimaker Cura 4.11, so there is nothing to replace that pattern with.

    Well darn... That's just one of the settings that is not working so I can assume that all the others are no longer supported either. I wonder why these were done away with.

    They were features of Cura LE, but were never part of Ultimaker Cura. They are not "done away with"; they were never there.

    I think they were never there in Ultimaker Cura.

    Oh. I guess that makes sense then. 

     

    The main issue I have with LE is the inability to install plugins, specifically some of yours actually.  In the latest version of LE the "browse plugins" which is supposed to open the marketplace is broken and always blank. I'm not the only user with this issue, their forums are full of unanswered questions about it.   I had been using vanilla Cura with my old printer connected to octoprint, however without the marketplace for LE, the only way to install plugins is with a .curaplugin file. Not all of the plugins in the marketplace have releases.

      • 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!
          • Thanks

      • 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.
