Hello ,

Can you send us a picture, a 3D, a plan of your A & C axis ?

Thank you

Hi JackRay,

Sorry for late reply

I have attached the link of a video of my system working on TCP configuration for XYZAC Kinematics.
share-me.video/video/FKNgtZV2ztL2biBngHb...IVvO4eMRvFGbj7JKHa5T

here you can see that the Z-axis is not following A-axis properly.
Any idea/suggestion why is it happening like this.

Thanks in Advance

Regards
Abhishek

Hi,

Greetings to all.

My 5-axis machines was running fine with the same INI, But as my Motherboard died and I changed my System and I also shifted my machines to other location.
Now my 5-axis TCP is not working properly as I can see a small jump simulation of Linuxcnc but in Machine there is no jump and because of this it derails from the actual path as you can see in Image. 



Now I am not able to figure out why it is doing so..

I have attached my INI and HAL file.

If I understand correctly then the machine moves are correct but the tool path inserts the angled move. I'm not sure what you are using the 'U' axis for but you may want to remove that from the plotter and see if that fixes the issue:

Change this line
GEOMETRY = XYZ-ACU

to
GEOMETRY = XYZ-AC

Hi Aciera,

Thanks for the Reply.

I tried what you suggested but but there is no change in how the Machines shifts for actual trajectory because of shift in Linuxcnc simulation.
I am using Linuxcnc 2.10.0 Version.
Is it because of some glitch in Kinematics ?

I doubt it, but I haven't tested 'sim/axis/vismach/5axis/table-rotary-tilting/xyzac-trt.ini' in 2.10 lately. I would expect this to be related to your use of the 'U' axis.
Have you tested this on an unmodified 'sim/axis/vismach/5axis/table-rotary-tilting/xyzac-trt.ini' simulation configuration?
