Thread: Mach3 custom USB Keyboard
I saw this pendant on eBay, but where is the fun in that? I like making my own... even if it cost a bit more.
Also, it is fully customizable... any button, any enclosure, any function.
You could even connect it to a arse pressed button solar or gas powered if you wanted to...LOL... :)
Any prices or details? Preferably not gas powered.The more I know, I know, I know the less. (John Owen)
I used a MAME pcb for my joystick interface which basically maps the correct keys from the keyboard. The supplier customised it for me for free. It could also be used to map any other function the keyboard does for your software, ie axis control, speed override, home functions. It was a nice little project to build.
What do you requiere exactly?
Do you want to build the all think from scratch ?
Have you got any electronic background?
I have electronic background and would probably go from scratch, but if you have pcb.s or anything would like to discuss with you. It looks from your pics that it can be configured for a fourth axis which would serve me well.
I don't have any PCBs done as it is too expenssive... I was hoping to get a bit more interrest from members of this forum so we could group a PCB order to get the price down. But it did not happen so....
I can provide you a schematic and an image to program in the PIC microcontroller.
For the 4th axis, At the moment all buttons are used X+, X-, Y+, Y-, Z+, Z-, Sart and Stop.
But I CNC the top cover of the enclosure myself. If could be machine differently to add a 4th axis... Or even use a different enclosure bigger to do more ???
The PIC micro controller I used has plenty of I/O spare so....
Have you got a PIC programmer ?
