Move the machine as close as possible from the Y+ limit (back of the machine)
Attach the hose on its first point thanks to the cable ties. Pay attention to the way you place the cable ties (refer to the white arrows).
Install the 5 remaining cable ties all along the Y-axis, as shown in the pictures below.
Once the hose is fixed, move your Y-axis from back to front a few times, to be sure that nothing is getting blocked or squeezed. Pay extra attention to the Y1 motor not touching the hose.
Finally, once everything is attached, you can cut the cable ties leftovers.
Make sure the gantry can properly move all along the axis.
