On my Hardinge HNC lathe, I am using a small HAL component here: http://www.wallacecompany.com/cnc_lathe/HNC/emc2/turret.comp which coordinates a rotate solenoid and stop solenoid relative to a binary slot encoder. The interface to the component is setup in the turret section here: http://www.wallacecompany.com/cnc_lathe/HNC/emc2/configs/hnc_io-3a.hal It's just parport pins and HAL. I am planning a similar setup for my Shizuoka mill, except there are five signals to control. http://www.wallacecompany.com/machine_shop/Shizuoka/tool_changer_video.html The changer has some intelligence built in, so allot of the details are taken care of. The component will maintain and react to the changer status on each servo-thread loop. This changer doesn't have an encoder, so if I am going to be able to call a slot by T number, I will have to keep a slot position history. I'm thinking it may be easier to make encoder like the HNC's. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
