Nope. The JogIt pendant is a very simple device. Pushing any button sends a keyboard command, the same as if the key was pressed on a keyboard. The difference is, the pendant buttons are specific to running a CNC machine, the simplified pendant keypad is laid out ergonomically for CNC control, and the keys are labeled for their CNC function as opposed to a regular keyboard that has letters and numbers and symbols spread all over the place. There is a pair of buttons to increase and decrease the jog speed so you can jog slowly for delicate work or you can go fast if you're in a hurry when making long moves. There are six dedicated buttons for jogging the X, Y and Z axes, each in both directions. The JogIt pendant also allows homing, running programs, stopping programs, pausing and resuming programs, control of two dedicated outputs AUX1 and AUX2 which might be used for flood and mist coolant in some applications. Because the JogIt pendant is essentially a keyboard and it's open source, you could easily add a normally open push button in series with the power from the USB port, so that button would need to be pressed before the other buttons were active, but so far I haven't found it to be a big problem. I just don't press buttons when I shouldn't. :-) An MPG is very cool and definitely has the real CNC feel about it, but I find the JogIt to be quite adequate for my needs, and I do love the plug-n-play aspect of it. If you have an open USB port for the JogIt, it's gonna work with no HAL file manipulation, no wiring, no searching the internet after it doesn't work, etc. There are a couple of demo videos on the KickStarter page I linked to in my last post.
