Depending on whether you want to be able to home the two motors independently or not, you can either simply connect the step and direction signals from one stepgen to two drives (either in hardware or HAL, depending on your preference) or use gantrykins. Gantrykins is a kinematics module that allows you to map the XYZABCUVW values to specific physical axes (technically to "joints") fairly freely. You would map "Y" to joints 1 and 2 (or maybe 1 and 4) then you can jog the motors independently in joint mode, but then once homed you can switch to cartesian mode and they will move together in response to "Y" values. Have a look at the stepper gantry sample file to see how it is done, it is reasonably straightforward. Done right, and with separate home switches for each side, you can easily arrange a self-squaring gantry, -- atp ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
