The Y axis is the one that travels from front to back.
This axis is on top of the X axis, so it travels with the x motion to.
The Y axis, also called gantry, caries the Z axis so the circle is round after this one.
With the completion of this axis I will have 3, and come very close to have a running machine.
Again, to start I use some parts, that will be replaced when my money tree gets bigger.
For example I already know that there will be ball-screws instead of Trapezium lead-screws in the end.
Below you will find the posts about my Y axis / gantry, and again some modifications.
