I have seen a long time ago on a website a way to align y axis to x axis. Unfortunately the website has been closed!
What I mean is:
If y moves 100 mm x should be automatically corrected by 0.1mm!
Can someone help me there?

"millkins" does this, but might need changes to work properly with a dual-motor axis if you have one.

Yes I have 2 motors on the Y axis.
I have now experimented in a sim today, but unfortunately without success. I keep getting an error message that the limit is exceeded! I suppose that is but on the joint assignment!
Then I tried in the millkins to add a second y axis, but honestly I have no idea what I'm doing .....
Is there anyone who has the millkins with two y motors running?

The sims have simulated limit switches and do tend to get a bit tangled up sometimes. (Hmm, we should probably try to fix that)
Are you using auto-squaring (ie, there are two home switches for Y and negative homing sequence numbers in the INI?)

I seem to remember writing a custom component to do this for another member in a few lines of code. Its here on the forum somewhereI have seen a long time ago on a website a way to align y axis to x axis. Unfortunately the website has been closed!

Here is a version of millkins for an XYZY configuration (XYZY is hard-coded in)
sudo halcompile --install skewkins.c
Should install it. If you don't see a "cp ... skewkins...." towards the end of the output then it hasn't worked. In that case paste the output here.

Hello Andy
Thanks for the info ...
I already have 2 limit switches on y and also the negative homesequence.
My partal is made of MULTIPLEX and has a length of 3000mm.
Unfortunately, the table with the side guides is 1mm wider at the back than at the front and so I have quite exaggerated a "V".
I have now so mediated that I have on both sides now at 1000 mm in y 3/10.
The machine is used to make furniture.
Thanks for adjusting the millkins.
I will try it out ......

sorry that I have not yet answered but in the workshop is currently stress announced!
But I have just tried it.
skewkins has compiled
But if I now change the entries in the hall I get an error:

Ah, interesting....
This is related to the addition of switchable kinematics to LinuxCNC master.
Add
to the .c file just above the "EXPORT_FUNCTION" lines
