    I'd be willing to provide a pendant to someone that could integrate it to Grbl (Grbl Panel) and/or Smoothieware!?!?

    @GerritV <- guess that means you (-:

    I don't know about smoothieware at all.

    I posted a "Feature Request" for the Pendant over on github/Grbl-Panel, not sure how much movement it will get as Gerrit seems like a pretty busy guy...we'll see what happens :)

    So I really like the controller based on the video. My problem is how are you going to do the power. I see that you are using one power supply at the top. Lets assume you have 4 axis that use 4.2A each. You would probably want to be safe and have somewhere around 20A @ 48V. Normally there are no small power supplies that would have that much power that would fit in there. Unless you plan on having a lower voltage with more amps in there. The problem with less voltage is you wont get the top speed out of the motors. It would be great if you would make a larger size one that can hold two power supplies.

    Thanks Steven

    I was looking at a local stockist of pendants yesterday. *Expensive* here. The cheaper one is RS232 only (roughly USD74), the much more expensive one is USB and has an LCD. So, space for an open source one that people can just build for themselves. Maybe configure an Arduino as a HID keyboard device and just send keystrokes.... easy enough for a GUI to accept keys for jog motion etc.

    a long time ago I wrote a TSR program for MSDOS that would accept serial characters from a barcode wand and inject them into the keyboard buffer. Thus the target program did not need to know there was a wand, it thought the user was typing the barcode number. So I am thinking of the same transparency and work across many GUI's without integration.

    David,

    I'm not sure what language you're speaking...TSR, MSDOS, HID, it's all foreign to me LOL.

    Truthfully, I get some of it, however, it's way out of my wheel house for sure!!! So again, I'd be happy to provide Pendant and even an Arduino to someone that could make this happen...I think it would be great for the community as a whole, and would be a welcome add-on to many of the machines/kits offered by OB. Is THIS ONE something that would work with a RS-232!?!?

    I do wonder how the keyboard would distinguish the movement multiplier from the handwheel (X1, X10, X100). I would want to be able to control the length of the movement through the pendant as well, and currently I believe that change is handled through the software, not the keyboard (please educate me if I'm wrong ;-)!?!?

    It might be a bit demanding of me, but if all the pendant could do is mimic the key strokes, I'd just use a mini wireless keyboard instead...if that would work!?!?

    Thanks for all your input, I look forward to hearing more :)

    p.s. I think we are getting out of the Apex realm now, so I wonder if this warrants it's own thread!?!?

    Sonny

    TSR = Terminate stay Resident, like a Window system service
    MSDOS = the only real operating system
    HID = Human Interface Device = a USB desgination for a device like a mouse or keyboard
    That is interesting but missing much of what I would want. I want jogging of course, but also 'set zero for current axis'. To me this is the point of a pendant, you can go over to the machine and eyeball the zero position and set it without having to be near the main control interface.

    I was looking at this Hobbytronics. MACH3 Wired COM and USB Pendant - 4 axis

    I have been thinking to use a gamepad-like joystick plus some buttons. (I hate membrane keypads)
    Integrating an actual gamepad could also be done so long as we can find a reference for what it sends down the USB cable.
    that is what the Arduino in the system would do, it takes the button presses and wheel motions and turns them into (name a GUI) friendly keystrokes. The GUI thinks it is getting input from a keyboard.
    Yep, that works. But, can be quite hard to find that 'stop jogging' button in a hurry (-:
    probably....

    Hi Adam, we are working up prototypes and fine tuning some additions to come so no ETA as of yet but will shout it out as soon as it is, we can't wait!

    If you are looking to get started with Arduino there are a plethora of videos on youtube. There is one guy who is quite helpful https://www.youtube.com/watch?v=d8_xXNcGYgo.

    Depending on your level of proficiency in coding and electronics the learning curve can be easy. Honestly if you start small and work through the stuff you will get to the point where you can use them for a lot of cool stuff. Hope this helps.

    I am excited to see when we can order the Apex. May I please give you my money?

    When will you release the price and be available to buy it?
