around the wheel of the tensioner and install the end of the belt in the other slot
on the bottom of the hot end assembly (FIG 13).
• Install the tensioner cover over the wheel and thread the adjustment wheel on to
hold everything in place (FIG 14).
• Now the thread another M4x16 Button Cap Screw [BB] from the rear into the
remaining hole, through the plate, into the aluminum extrusion. While tightening
make the edge of the plate flush and parallel with the top of the aluminum
extrusion (FIG 15).
• Install the M4x14 Flat Head Screw [DD] into the front side of the tensioner cover.
Tighten the tension adjustment wheel until the belt has a slight tension (FIG 15).
Verify the pre-installed Y-Axis belt tension is similar.
The tensioner cover is plastic and will crack if over tightened.
Only hand snug all fasteners with the hex keys [RR].
DO NOT over tighten the belt, it will stretch out prematurely.
Tightness is not critical. The belt only needs be tight enough to
not skip a tooth when traversing rapidly.
