Y-axis has its own end-stop for homing purposes.
But when Y-axis moves to "dock" the tool changer there is another end-stop involved (the input I am planning to use is U-axis end-stop, but I could use any other input if better).
Y-axis homing works as expected, and each time a tool change I have to send the Y-axis back (at a certain X location) so it will engage with the tool changer. I am backing the Y-axis for that purpose until the carriage "contacts" with a special end-stop for that only purpose.
One approach that seems possible is to change config as if now the Y-axis has to use this new end-stop and then to do a homey.g, but that approach would alter the Y-axis coordinates (nothing that could be fixed) doing a new (and now proper) home of Y-axis now using the real Y-axis end-stop (at a different X-location so I am not knocking down the tool-change mechanism).
But I wonder if there is another way to achieve a similar result that would not alter the Y-axis origin of coordinates.
Thanks a lot,
P.S: drawing is coming soon
