XYZAC 5 Axis Setup Offsets in HAL

Hello,


is it possible to set up the offset of the C-Axis relative to the A-Axis when both do not intersect each other in reality?

I only found the command to offset X,Y and Z. Is there a similar command for D_x and D_z?


Thanks in advance!

If you will use "Axis" gui that is default, when you will add additional axes, they will be addded automaticaly.
Offsets you can set similar to xyz axes.

@aleksamc
I think he means the offsets in the setup for the XYZACkins kinematics.

@mittim
I'm not familiar with XYZACkins.
Maybe have a look at XYZAC-trt kinematics. See section 5.2 with Dy, Dz parameters:
linuxcnc.org/docs/2.8/html/motion/5-axis...ol_with_work_offsets

Yes, I mean the offsets in the setup for the XYZACkins kinematics defined as D_y and D_z as described in section 5.2.

Hm, it's not clear to me what you are asking as the hal snippet you posted seem to have the required parameters Dy and Dz. If the A and C axis don't intersect then Dy would be the offset. As you have Dy=0 then the two axis intersect.

I am wondering, if it is possible to set the values Dx und Dy in any form, as it is almost impossible to make A and C to itnersect each other.

Im sorry but I still don't understand where your problem is.
If I understand correctly then you have an XYZAC setup, as in Figure 6, Section 5.2 of the above document.
If so then you can have offset Dy and Dz as shown, there is no Dx in a XYZAC configuration as the A is colinear with the X axis.
In Figure 6 the A and C axis don't intersect. Neither horizontally (Dy offset) nor vertically (Dz offset).
Both of these offsets (Dy and Dz) you seem to be able to define in the Hal-sippet you posted.

Yes, exactly I have an XYZAC setup.


Thanks alot, that´s exactly what I needed to know. I will set up my A to the C Axis tomorrow and was wondering how accurate it has to be in regard of the offset of the intersection of axis A to C.
