Printed Drag Knife DIY CNC works pretty well

  • I decided to make drag knife by using 3D printer with ABS material and common metal parts.
    You need any CNC. I built CNC by myself, it is combination common alluminum profiles, particle boards and printed ABS parts.
    For running G-code I used Arduino board with Sprinter. As the software for generation g-code I use Simply Cam 2,
    you can import your data from vector programs like Corel, Illustrator...
    There is the result in video. Let it is an inspiration for you to make one.

    great, many thanks for sharing this; I had never thought before how the boxes and cartons we buy are made. I guess this is it...drag knifing

    • @edgeremover

      Not really, if you buy some carton boxes, I am sure that they are not drag knifed :) It would be very slow in mass production. They use press machine with blade.

    Nice! Top notch work. I linked over from Reprap forum and you're right, it is inspiring. :)

    The edge remover is gone, it was a very nice idea

    beautiful, are the 3d printable files available?

    IT'S OK! thank you so much ! got it ! encomodar sorry again , but I have one more question. How is control of the " turning " of the knife when making a cut in a curve . You make the design of the curve in a CAD program and he sets the knife angle in cuts ? Sorry this lot of question is that in Portuguese ( Brazil ) and in forums not esou meeting on the subject. very grateful for the attention !!

    • @edgeremover

      +Leonardo Huss Knife rotates by itself by slighly touching the material, you have to set it. Turning is doing by circle way like you can see at strange looking corners 2:24, that is the turning of drag knife, because the knife is dragged so it is needed. Just look carefully at video, it is no sience.

    holy crap, thats amazing

    I'm wondering why you use a second set of bearings on the pivot pin. Wouldn't it be enough to have the pin fixed and then the bearings built into the drag knife fixture would allow it to rotate around the pin without the pin needing to rotate also?

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว

      +pyronaught Hi, you are right, you can use also solid spindle - mounted rod. Only reason why I did it, was that I wanted whole axis to be rotated. Rotation is then smoother.

    what CAM software are you using? Did you customize the tool path to raise itself at the 90 degree corners

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว +2

      +nick durrett
      I did not have CAM for it, just drew the whole path in Corel Draw with corners like you can see in video. This raising I set in Simply Cam 2.

  • @LeoHusss
    @LeoHusss 8 ปีที่แล้ว

    It is possible to find some open source for control of the drag knife? With the Mega 2560 .
    IM not finding. Since already I am grateful for your attention! Great job!

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว +1

      +Leonardo Huss You probably are looking for some sort of software generating g-code with drag knife offset. I am sorry, cannot help you with that. I drew the curve with drag knife offset in Corel Draw and then generated g-code from simply cam. Some software can do it for sure, but they are not open source I think.

    hi, what 3d printer you used to make parts of your cnc?

    • @edgeremover
      @edgeremover  7 ปีที่แล้ว

      Frankly, dont remember exactly, just ordered some Rework version printed plastics from someone and other things I made by myself, like frame, bottom under heat bed...

    Hi. I am from South Africa. Your printed drag knife is very cool. I am also very interesting in your CNC itself.
    Do you have some plans or description of it? It seems if all the parts were also printed on a 3D printer.

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว +3

      +Paul Roos
      Hello Paul, yes a lot of parts are printed. This CNC was good just for learning of basics, its really slow and some axis are not solid enough, mainly X. On internet you can find much better types of DIY cnc with low cost, just search.

    I need this product to my x-carve cnc machine. The knife and the roller. Where can I buy it?

    • @edgeremover

      Sorry, I do not sell it.

    Lovely! I wonder do you sell the model for the 3D printer?

    • @edgeremover
      @edgeremover  7 ปีที่แล้ว

      No, I do not sell models, I dont not have files anymore.

    how did you generate the toolpaths?

      I am sorry, do not have actual schema. Did it for fun. I did not storage it.

    hi, how much distance/shift do you have between the rotation axis and the knife point?
    tx

    • @edgeremover
      @edgeremover  7 ปีที่แล้ว

      Hello, actually it depends on blade type, now I use around 1,5mm. You have to test it to find optimal conditions.

    • @aeschlimannluca
      @aeschlimannluca 7 ปีที่แล้ว +1

      +edgeremover thanks! Will try with 1,5. I tried with 0,7 and it's shredding everything:-(

    • @edgeremover
      @edgeremover  7 ปีที่แล้ว

      0,7 is really low and problematic, if you cut thick material you should choose much more. Try 2mm.

    Simplycam 2? Does it have a drag knife calculation?

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว

      Jonathan Lowe
      No, it does not have, you have to draw it.

    • @chubmcy17
      @chubmcy17 8 ปีที่แล้ว

      edgeremover You draw all the tool paths?

    • @edgeremover
      @edgeremover  8 ปีที่แล้ว

      Jonathan Lowe
      Actually I did it this way. First I draw the line for travel the knife, and the corners where knife is suppose to be turning I draw circle with offset. Then I import it into the
      Simply Cam2 and generate g-code. Yes, It could be easier with some software which could does this offset calculation for turning.
