Replace Z Endstop
(1)
Z Endstop Clamp
(1)
M3x25 socket head screw
(2)
M2.5x14 socket head screws, reused from disassembly
process
•
Loosen the (2) M3x12 screws to remove the Z-endstop
clamp from the 10 mm shaft. The endstop can be found
inside of the build area of the machine, near the top
of the rear 10 mm shaft.
•
Remove the (2) M2.5x14 screws and printed piece from
the wired assembly. Set these screws aside for reuse.
Being careful to not damage the connectors, remove the
printed piece from the switch and LED.
•
Insert the LED into the Z Endstop Clamp. To do this,
the LED must pass through the hole in the Clamp from
the side having a large notch, and the wires must be
oriented to seat into the notch.
•
Carefully bend the soldered wire connecting to the end
stop switch so that once the LED is in place the switch
can be moved into the position shown in the picture on
the bottom right. The two holes on the switch body will
line up with the two on the Clamp, and the metal lever
should be on the opposite of the flat side of the Clamp.
•
Secure the switch to the Clamp using (2) M2.5x14
screws.
•
Using a narrow tool like a hex wrench, push against the
LED next to its wires until its round surface reaches the
other end of the hole and comes to a stop.
•
Slide the assembly onto the 10 mm shaft near the back
of the printer with switch lever facing down. Feed the (1)
M3x25 screw, but do not tighten.
•
Slide the clamp to the top of the shaft until the flat
surface is against the frame of the printer. Make sure
wires do not get pinched between the components.
The clamp must be rotated so that the LED is facing
directly into the print area parallel to the X-rail on top of
the printer, and the switch body is square with the rest
of the machine.
•
Tighten the clamp into position with the (1) M3x25
screw taking caution not to over-tighten. The clamp is
fine if it is snugly in place but can still be turned on the
shaft with a little pressure by hand.
•
Adjust bed height screw according to new z stop.
