5 Axis ParPort Stepper Setup with RTCP

Hello Andypugh,

i have already studied that yeasterday before your reply, but it is little tricky for me, i am not able to understand how to create joint just between XZand B axis ? what is function of W axis in sample 5 axis config. ?


can you throw some light ?


Thanks.

You need to decide what the G-code axis words are going to mean in your config, then do the geometry to derive the equations for coordinates to joints and joints to coordinates.

Hello people,


I did checked Kinematics.c and all files, i found myself dumb. :S ... i dont get idea where to start from. basically i think my task is simple but i dont know where to start from. so thing is See rotary table in C axis will not have any relation with any axis for any compensation, it will be always XZ-B but i dont know how to unlink C Axis and Y axis from kinematics hal and ini... somebody give me direction ....

Start with a pencil, paper and trigonometry.

okay yes i can do math for XZB and thing is its already configured in 5Axis kin. i am testing right now. is it possible to modify it ??

If you are using 5axiskins and that is geometrically correct for you then you probably only have to change the pivot-legth HAL parameter to make it suit your machine.

I am still not clear what your degrees of freedom are.
