The way I got around this problem is to use the hal_input component with a USB game port adapter such as this one <http://cgi.ebay.com/15-Pin-GamePort-to-USB-Port-Adapter-for-Flight-Joystick_W0QQitemZ310199439311QQcmdZViewItemQQptZVideo_Games_Accessories?hash=item483953cfcf>. These ones <http://cgi.ebay.com/USB-to-15-Pin-Joystick-Gameport-Converter-Adaptor-Cable_W0QQitemZ260550295897QQcmdZViewItemQQptZUK_Computing_ComputerComponents_JoysticksJoypadsGamepads?hash=item3caa020159> don't work very well.
These adapters work with the absolute position of a potentiometer so there are no problems with losing position after a shutdown. It is also much cheaper than using encoders. If you want you can use a hacked joystick but the adapter is more tidy. I did find that they are a bit sensitive to EMI so it is best to keep them well away from power wiring. I know this goes against the EMC way of doing things but who is going to want to use a GUI based override when you have a nice convenient knob on the front panel? I use this for feed override, spindle override and rapid override. Les Kirk Wallace wrote: > Thanks to some help from the IRC (tom3p), I got the encoder working with > AXIS's spindle override.
