5Axis Kinetic from 2.8 on 2.7x

Thank you , i will try ... ...

Hello ,

I'm back after a few days of absence.

So I configured my .ini / .hal files, I have a little problem with my .hal file when I initialize the pins

xyzac-trt-kins.x-offset
xyzac-trt-kins.z-offset

X and Z offsets are the offsets from the center
of rotation of the C axis relative to the center
of rotation of the A axis.

Hal Input pins:
xyzac-trt-kins.x-rot-point
xyzac-trt-kins.y-rot-point
xyzac-trt-kins.z-rot-point

X, Y and Z rot-point pins represent are the
offsets of the center of rotation of the A axis
relative to the machine absolute zero
coordinates.

Can you help me please .

thank you in advance

Hello,

There, I have arrived at the goal. I have developed a 5 axis CNC machine with Trivkins/Xyzac-trt permutation with activation codes M428/M430

Attention, I didn't do it alone, I would like to thank all the community of the LINXCNC Forum for all the answers that I could ask.

A special mention for Aciera who piloted the software part of my project, it's with an enormous patience that helped me to search the sources/compile Linuxcnc 2.9pre.

A big thank you to all the people who develop this great software and make it evolve.

Hello ,

I would still need your help please.

2 questions:

The first concerning the backup of the complete system with all the updates we have made and therefore Lcnc2.9.
I cannot back up my system with "dd" or "ddrescue". I don't know if Real Time is preventing manipulation.
Would you have a simple and effective solution?

I am looking to make a "bootable" image on an external USB drive.

The second is at the "axis" graph level, my graphing tools do not correspond to the path of the "a" axis, I cannot find the reason.

Thanks for your help

- I usually use clonezilla to clone my ssd's. I can't comment on how to create a bootable usb as I have never looked into that.

- As for the graphics, you can do some customizing using GEOMETRY in your INI file:

GEOMETRY = XYZABCUVW - Controls the preview and backplot of rotary motion. This item consists of a sequence of axis letters, optionally preceded by a "-" sign. Only axes defined in [TRAJ]AXES should be used. This sequence specifies the order in which the effect of each axis is applied, with a "-" inverting the sense of the rotation. The proper GEOMETRY string depends on the machine configuration and the kinematics used to control it. The example string GEOMETRY=XYZBCUVW is for a 5-axis machine where kinematics causes UVW to move in the coordinate system of the tool and XYZ to move in the coordinate system of the material. The order of the letters is important, because it expresses the order in which the different transformations are applied. For example rotating around C then B is different than rotating around B then C. Geometry has no effect without a rotary axis.

Thank you for this info . I get it .
But I just made a big mistake. when I wanted to save my disk, an error happened. Now I can no longer open linuxMint, it tells me that my "login" is incorrect. I cannot access my session. I only have a "terminal" interface. I am desperate after all this time. I had reached the end.
Can someone help me ??

Thank you
