Hello, I have a Servo to go card running on one of the earlier bdi distros. I think it is 2.18. I cannot get the card to spit out a voltage. I tried the diag program "lstg" and the voltage out and in worked fine. I have the base address set to 200. I am not sure what I am doing wrong, could someone send me a copy of their ini file or any other relevant files that have this type of configuration setup successfully? Also, I would like to use tachogenerators as a type of feedback. Is this possible? While I am at it, is there a way to set the zero out the counters on the gui without sending the machine to the home position? Thanks, Jim |

Hi Jim I'll try a couple of your questions. What kind of feedback do you want from the tachs. They put out a voltage that is proportional to speed and are often used by servo drive amps to compare commanded velocity with actual. The EMC really does not have much for reading an analog input from the STG but I suppose that someone here could work up something like a spindle speed readout using one. You can use the coordinate systems g54-g59.3 to set any place in your work envelope to zero. I'd use a little script that is available these days with the tkemc graphical interface that helps you set these. It shows up under the scripts menu as "Set_Coordinates. If you don't have it with your distribution, we may be able to upgrade just the display parts of your system.

Hi Ray, You had mentioned a newer version of your mini.tcl gui to me at NAMES. Can you place a copy in the linuxcnc.org dropbox when you get a chance. Thanks, Jim |
