Hi Giorgio, I don't totally understand what you're reporting, but I think maybe you're running into a problem with different units being used in different places. The .ini file file has [TRAJ]MAX_VELOCITY, [AXIS_*]MAX_VELOCITY and [JOINT_*]MAX_VELOCITY in machine units (mm in your case) per second: http://linuxcnc.org/docs/devel/html/config/ini-config.html#_traj_section http://linuxcnc.org/docs/devel/html/config/ini-config.html#_axis__lt_letter_gt_section But the Axis GUI presents Max Velocity in machine units per minute. I just ran this test: I started the sim/axis/axis_mm.ini config, and saw that Axis shows a max velocity of 3200 mm/min. This corresponds to the .ini file's [TRAJ]MAX_LINEAR_VELOCITY of 53.34 mm/s. I then used halcmd to poke at halui. I first saw that halui.max-velocity.value was 53.33333 (mm/s), roughly as expected. I set halui.max-velocity.scale to 0.1 (mm/s) and then halui.max-velocity.decrease to 1. That made halui.max-velocity.value change to 53.23333 mm/s, and the Axis Max Velocity slider changed to 3193.9 mm/min, which is also right. I also tested with halui.max-velocity.scale set to 10 mm/s and 100 mm/s, and both worked as expected. I also tried on an inch machine with both linear and rotary axes, and while there's only controls for max linear velocity, that config worked as expected too. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
