Hi There,

I am wondering if there is a technique out there that can print text as cursive letters using just the nozzle width. In short, the tool path should be cursive and the nozzle deposits the material at .4mm. Effectively i will get a stroked path of text. I believe @DAID has an approach for it.

The current problem with slicers is that whenever i use text it tries to infill making the quality bad. I am looking for constant width stroke that represent text.

Any ideas or suggestion.?

Uma

    If I understand your question, you want to print cursive letters using only a single pass of the nozzle so the "stroke" is .4mm. Is that correct?

    Unless Daid has a utility to do this, one way to do it is to use any of the free engraving software (google text to gcode).. However, it isn't a complete solution. They generate gcode for 3 axis engravers or milling machines. 3D printers are actually 4 axes, the normal X, Y and Z of an engrave/mill plus E for the extruder material feed.

    Note this only works for one layer. So let's say you used one of the text to gcode utilities for an engraver/mill, you would set the Z to be the thickness of the layer say .1mm. The gcode would would have all the moves for the X, Y and Z. However, the E value would be missing.

    So you would a second process that reads the GCODE and calculates the amount of material to feed for the move and add it to the moves as the E value. You could probably do it in excel.

    What type of printer? UM1 or UM2 or other?

    @anon4321 thats exactly the problem i am trying to solve.

    I am playing around with such text to gcode software. The problem i find there is the fonts are made using infill (regular ttf fonts) which impedes the cursive text output. Whereas what I get is a two oulines for any character which leads to overlap and other material depositing issue. I agree this is a start but I have seen Daid doing it in one of his test prints.

    I have a UM2 and another makeXY printer.

    I did? That's special, as I don't recall doing this.

    But, you should look for CNC milling fonts, or lasercut fonts. That should help you. I know they exists, fonts with just a single line.

    If I understand, this is what you DO NOT want correct?

    TextToGCODE

    Because 1, it's not cursive and 2, it is "thick" even though it is an outline (even if it isn't filled) correct?

    You want the equivalent of taking a pen and writing in cursive but using a single pass of the print head in place of the pen, correct?

    The previous path doesnt work for me (darn that url parser):

    If you can get a gcode out with something that suit your need I can look at adding the E value to it and duplicating/reversing the layer to get the needed height.

      • 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 5.3.0-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.
