This is now fixed in update_ini.

It would be valuable if you could try running that on a copy of your original config to see if that produces a working setup on your actual hardware.

There are still some UI issues with this.

There are some bits of code that assume joints 0-8 map directly to axis xyzabcuvw

For example, in touchy/emc_interface.py

Code:

        for i in range(1, 9):
            h = " "
            if self.emcstat.homed[i]: h = "*"
            if am & (1<<i):
                letter = 'XYZABCUVW'[i]
                set_text(self.relative[d], fmt % (letter, relp[i]))

Here self.emcstat.homed[ i ] maps to the joints 0,1, while "am" (the axis mask) and "letter" use i as the axis number (index) - which doesn't work because of the gap in joints.

This stops the homed flag from being displayed for Z.

I have an XZ lathe, and there is a problem with the display of the homing symbols in Touchy, but the axis does home.

There is a problem with unhoming, though, as I recall.
