TL4100 Top 5 Build Tips
1: Top Plate
When assembling the top plate, align the top of the top plate brackets with the top of
the rods. This can be done by placing a hard flat object (such as a ruler) on top of the
plate and pushing down until the rods are touching the ruler. Then tighten the screws.
The top plate will then sit above the rods. If the holes in the top plate do not line up
exactly with the holes in the top plate brackets, the rods may be pushed out of
alignment and cause the carriages to jam. Lifting the top plate by 5mm also gives you
5mm more of travel for your calibration screws, which makes calibration less likely to
damage the bed.
2: Extruder thermistor
If you encounter a MAXTEMP alarm during initial testing, chances are the fault is
with the extruder thermistor. If the extruder is reading above 700 degrees, then the
thermistor has a short circuit. It appears that many cases are caused by the bolt cutting
into the insulation on the thermistor wires and shorting them together. A temporary
fix for this is to undo the bolt completely, and then restart the printer and see if the
error has cleared. A more permanent fix is to use a short length of WS5504 Vidaflex
Tubing to reinsulate the wires before tightening the bolt. Keep in mind the extruder
can get above 200 degrees, so any repair has to be able to handle this temperature.
3: Limit Switch Wiring
The limit switch wiring is in a very awkward spot, and it is very difficult to push in
the plugs after everything has been installed. To make things easier, the wires can be
installed before the limit switch is installed.
Using the below colour code ensure the correct limit switch is installed on the correct
tower. Also note that the ends of the wires are different and the plugs with the middle
slot empty should be plugged into the limit switches. If the wires are fitted wrong, the
limit switches will not work.

Y: black and green
Z: black and yellow
4: Wiring
The included manual is very brief on instructions for the wiring of the printer. The
following detailed guide may help.
Thread the cables from the extruder through the hole in the top plate.
Turn the printer upside-down and point the power socket towards yourself. Find the
following cables.
These are the mains power (240V) cables. Ensure that the printer is not plugged in to
mains power, and that the main power switch is in the off position. Firstly take the
three long wires, and tilt up the protective barrier on the power supply. Loosen the
three left screws on the power supply, then insert the tinned cable ends and screw
down firmly. Ensure the red wire goes into the connection marked ‘L’ (live), the black
wire goes into the ‘N’ (neutral), and the green and yellow wire goes into the ‘ ’
(earth). Then thread the wires out to the top of the printer through the top plate.
Then feed the wires into the base through the side shield and attach the crimp ends of
the red and black wires to the switch side of the power socket module, and the green
and yellow wire to the power socket. The two short wires go between the switch and
power socket. From left to right, the wires are green and yellow, black, red, red, black.
The red and black wires going to the top of the printer are closest to the camera.
Find the single black and red cable. This is the main 12V power feed to the board.
Loosen the fifth and sixth screw terminals on the power supply and screw one end of
the red and black cable into it. Line up the black wire with ‘V-‘ and the red wire with
‘V+’. Then press the protective barrier down to lock it into place, and feed the cable
out the hole in the top plate like the other cables.
Following the other cables, feed the red and black cable through the side shield, and
attach it to the green terminal on the main board, ensuring the red wire goes to the ‘+’
terminal and the black wire goes to the ‘-‘ terminal.
Now find the three stepper motor cables. All three cables are identical- one end has a
six-way plug, the other end has a four-way plug. These short leads are for the three
stepper motors in the base.
Using the X, Y and Z marks made on the steppers motors when they were installed
and the X, Y and Z marks on the main board, run a cable from each stepper motor (the
six-way plug) to the main board (four-way plug).
The next cable is for the extruder stepper motor, and it is a longer version of the other
stepper motor cables.
The easiest way to feed this cable through is to take the four-way plug end and feed it
first through the top plate, and then through the side shield, following the path of all
the other cables. Then plug the six-way end into the extruder stepper motor.
Then plug the four-way end into the E0 connection on the main board.
Now thread the last four cables from the extruder back along the same path as the
other cables and back to the main board.
Strip about 5mm from the end of the extruder heater (these are the two thicker red
cables with a woven appearance).
