I don't know if any of you have seen it but I found a way to make a wireless pendant for our technos or Mach3 using a ipod touch or an iphone. I have been using it since last december. Here is a link to the original thread:
IPhone app to run CNC video
The wifi pad server software runs in the background of the controller computer and can be used when setting up a file and jogging. I have found that it is extremely fast and reliable, just like using the keyboard. In fact, it is a keyboard emulator! It can press a max of 3 keys in order. For an example I was able to set it up to auto zero the z axis by specifying the keys "T", "Z", "Y". You can just imagine not having to lug your keyboard around the machine to accurately position the spindle!
I made my button layout designed for the techno interface but since the new 4.12 interface came out, the layout user plasidboyy made is much more usable. He really did a good job. His picture of the interface and the gamepad file is atatched below.
The whole installation process takes about 10 minutes. I have found that this is one of the best modifications or add-ons that I have ever made to my Techno 4896. The best part is that it was completely free, no strings attached! (No pun intended!..... well yes there was!)
