5 Axis ParPort Stepper Setup with RTCP

Feed numbers into the calculations by hand, see if they come out the same in reverse.

I would use a spreadsheet for this. You will need to find the s2r functions in posemath.c (I think) in order to do this.

Where to find this file ?? and actually i am "0" in C ...

Don't worry about not knowing C yet. I didn't know it until I decided that LinuxCNC needed to support 3-phase motors.

All the source code can be found here:
github.com/jepler/linuxcnc-mirror

Specifically
github.com/jepler/linuxcnc-mirror/blob/4...posemath/posemath.cc

(Which is C++ and that confuses me)

Forget that, it has just been pointed out to me that the definition of s2r is right there in the kinematics file.

Hello Andypugh,

greetings of the day,

I have checked math.... i am so noob ... BTW do you have idea why it shows error like, "Must be in MDI mode to issue MDI command."

??

Also ... totally blank again ... how to break link of C from 5axiskin ...

It means what it says. What are you doing to prompt it?

I thought you said that you had checked the maths? If so, That's what you do, put that maths in the kinematics file and recompile.

After changing Value of C in line 44 and 65 ...

All the axes do seem to be homed, can you actually go into World mode?

I assume you just typed G0 X50? That's an MDI command, but you can't do that because at the moment you don't have an X axis, you are in Joint mode, and have Joints 0,1,2,3,4,5.

You need to switch to World mode, then G0 X50 will be valid (but might not work, for other reasons)

finally i am successful to break link with C axis .... youhuuuuu !! soooooo much thanks to AndyPugh i have won the war


now coming to next step how to touchoff too ?? i mean how to add tool offset ?? because this screen has locked tool touch button ... any ideas ??


Regards,
Ankit

You can't touch-off until you are in World Mode.

(then the coordinates XYZ etc mean something, and that is what the DRO shows.)

The keyboard shortcut is $ but you can also do it from the Axis menus (Machine? I can't recall)
