I am finally getting around to re-controlling a large (15' x 30') XY table. The gantry is driven by two oppositely mounted servo motors, axes Y1 and Y2. The current homing sequence works as follows:
Y1 and Y2 move together until Y1 resolves its home. Y2 then decouples from Y1 and resolves its home. Thereafter Y1 and Y2 are recoupled. I am trying to figure out how to do basically the same thing under Linuxcnc, or an alternate approach that works equally as well. I looked at the "gantry" example program, which does much the same thing with stepper motors, and uses gantrykins for the kinematics module. The home looks to be done effectively manually by switching between joint and world mode. Can this be done as part of an automated home sequence? Note: There is enough play in Y2 that it can move roughly +/- 2" from being dead on with Y1 before it will start to mechanically bind. Thanks. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
