Episode 420: DIY Shapeoko CNC Pendant

One of the great joys of being able to design with electronics is the ability to make your own custom tools. DJ recently picked up a CNC router and in order to make his life a wee bit easier, he’s designed and built a pendant that will allow him to more comfortably, and accurately set up his parts in the machine. Follow along as he tinkers his way to new gadget that, hopefully, will be of use or inspiration for fellow makers and CNC enthusiasts.

  • Very nice. It would be helpful to have the schematic. it would be helpful to have the layout for the front panel. I'll keep looking for them but both could be added to the Resources_DYI Shapeoko CNC Pendant zip file.

  • Hello , Thanks for a great project  I have 3d replicated all pieces and have programmed and succesfuly prototyped.  Wire restraint stl is not in the package.  Would you be able to direct me to where i can find such stl on thingiverse or was that something you created?  Any help would be greatly appreciated.

    did you ever get this done with the pro micro?  I would like to do it the same with the micro

  • Does this sketch use the "keyboard.h" library?  it refers to keyboard in many lines, but does not include this library in the sketch?  I am having trouble as it seems the sketch wants the keyboard library ?

  • Hi folks. I'm new here, an I would like make my pendant but only have an arduino pro micro, I would want to ask you if you can pas me the schematic of the connections for it? or may be somebody have it?

    tnanks in advance to all.

    Hi this project was done by .

    if your Pro micro has a 32u4 MCU on it the keyboard library will work.
    if its a variant with 328p on you will need to use a different Board.

    the actual schematics dont matter that much, just connect your switsch between the pin you want to use for it and gnd. optionally place a pullup resistor on each pin or use the pinmode Pullup function in Code.
    (either way you need to make sure each pin is always at High OR low, never floating or in a weird state.)

    All the code does is wait for an input and output a corresponding keystroke  over the usb port.

    I am having this same problem!

     

    I wonder if, from a code standpoint there is a way to simulate "holding" a direction push while the encoder is spinning vs. sending individual inputs. I'm a bad coder so, no bueno for me but it seems like rapidly sending a TON of inputs overwhelms Carbide Create.

    Another thank you, had same issue and that fixed it.

  • DJ - I have a working Pendant thanks to you!  I want to make the aluminum face place and need the CRV file to mill it.  Can you send it to me?

     

    Greatly appreciated!
