Re: [Emc-users] hexapod
What kind of hexapod are you building? I've have a long interest in them but, so far have only built single legs as prototypes. All of then had short lifetimes. What what kind of motors are you using and how many per leg? Finding good motors at a reasonable price is important. With only 3 per leg you need 18 motor and an 18-axis controller. With 4 per leg you have a 24-axis system and even if you only spend $100 per axis it costs a bit. The inverse kinematics is not hard to work out. Just a long and repeated application of the plain geometry and so trig.

[Emc-users] hexapod
Oh damn, I just sent my reply to Andy not to the list so here goes again. I just had Ray Henry on the phone and picked his brains. He says tk was written for the hexapod so one needs to find the hexapod kinematics. From there is should be easy or so he says. I've never tried it so all I can do is relay information. Sorry I can't be more help. An "old" wiki may shed more light.

Re: [Emc-users] problems in the change of my interface
The code of tklinuxcnc in 2.7.x purportedly supports nonlinear kinematics but there may be few or zero active users. The message: "can't read "::jogAxisType(1)": no such elem" means it is missing an ini file setting like: [AXIS_1]TYPE=LINEAR (or [AXIS_1]TYPE=ANGULAR if appropriate) Ref: https://github.com/LinuxCNC/linuxcnc/blob/2.7/tcl/tklinuxcnc.tcl#L998 The provided 2.7 sim config for the axis gui sets [AXIS_n]TYPE for all axes (0..8) and it starts up -- so you could test a simulation example by copying the axis-gui-sim sim config: configs/sim/axis/axis_9axis.ini to configs/sim/axis/tklinuxcnc_9axis.ini and then edit the new file to use tklinuxcnc: [DISPLAY]DISPLAY=tklinuxcnc The development branch (git master=2.8~pre) updates tklinuxcnc for joints_axes changes and is more suitable for non-identity kinematics applications but the tklinuxcnc gui is likely little tested any more. The development branch (master==2.8~pre) includes a hexapod simulation using the axis gui with a vismach display and it has been updated and maintained for joints_axis updates: https://github.com/LinuxCNC/linuxcnc/tree/andypugh/multispindle-master/configs/sim/axis/vismach/hexapod-sim -- Dewey Garrett -- 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
