Confusion setting up non-networked printer


Recommended Posts

Posted · Confusion setting up non-networked printer

I'm in the middle of a double whammy - setting up my first Linux distro (Mint), and setting up Cura 4.13.1.  I have a printer I built years ago, essentially a Prusa clone with a Ramps controller running Repetier firmware, which I have added as a non-networked Custom FFF printer.  My confusion is, how do I tell Cura how to talk to this thing?  It is connected via USB and I've been able connect to it with a Linux version of Repetier Host, but I don't see where in Cura I can enter anything like port ID and baud rate.  I get the feeling I've missed something obvious, but I have indeed missed it completely.

    USB printing functionality in Cura should be regarded as rudimentary. Ultimaker has no interest in improving the USB printing in Cura, since no currently shipping Ultimaker printers support printing via USB. The idea of the current implementation is that it auto-detects printers connected to serial ports. If it works, it works. If it doesn't, you are sort of on your own.


    I recommend disabling the USB Printing functionality in Cura (via the "Installed" tab of the Marketplace), and use OctoPrint instead. That way you have a separation of concerns; Cura does the slicing, OctoPrint does the hosting. If Cura crashes or otherwise needs to be restarted, that will not affect your prints. There's a good integration between Cura and OctoPrint via the OctoPrint connection plugin from the Marketplace.

    ahoeben, thanks much for the reply.  I've always been a little lazy about this operation, as in getting something that works OK and then living with it for years.  I'll make some time to try Octoprint.

      • 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.
