Install the X axis upper E-chain bracket
Mount the upper E-chain bracket to the 1/4-20 tapped
holes located in the side of the endplate, using the
1/4-
20x3/4” button head Screws
and
1/4” lock washers.
Install the chain
Attach the E-chain to the tab that extends out from the
upper E-chain bracket using two sets of
#10-32 flat head
Screws, #10 flat washers, #10 lock washers
and
#10-32
hex nuts.
Attach the other end of the E-chain to the holes located
3 ½” (64mm) from the end of the trough, closest to the
center of the machine.
Use the same #10-32 hardware as in the previous step
Before continuing, move the X axis back and forth through its full extent of travel. The chain should never feel as
though it is binding or under tension. If this appears to be the case, loosen the bolts holding the trough brackets
onto the table sides and adjust the position of the trough until the chain can move freely.
All wires and cables coming off of the gantry will be carried in the X and Y axis E-chains. Use this checklist to inspect
your cables before closing up the chain when you are finished:
□
X1 motor cable (coming through the hole in the center of the gantry beam)
□
X2 motor cable (located right above the upper E-chain bracket)
□
Y motor cable
□
Z motor cable
□
X axis proximity switch (coming through the hole in the center of the gantry beam)
□
Y axis proximity switch
□
Spindle or router power cord
□
Spindle fan cable (if applicable)
□
Z axis proximity switch (for ATC tools only)
□
Pneumatic air hoses (for ATC tools and optional air drills or pneumatic assists)
NOTE: As with the Y axis E-chain, keep the spindle/router power cord separate from the other cables.
This helps
to prevent electrical interference that may cause connection problems while you are running the machine.
