Hello there, I interested to build double head laser cutting machine, on some videos i see on youtube, now the double head machine on the x axis can adjust distance automatically, so operator don't have to adjust it manual.

In this forum, I want to know how that can implement? My technician said it was control from Y axis, that not being use, any other idea?

Also for the second laser head how the mechanism to control that laser head, is that using 2 x axis motor?

Here the video https://www.youtube.com/watch?v=qAhvM0Sw5bc (on 00:00 - 00:01)
