Scalar L: Z and Y axis wiring
here is a view of the machine once assembled and the heat bed on it.
Note the ‘ »Front » and the ‘ »Back » side of the machine.
In this section we are going to work on the BACK side of the machine
Y Axis motor
If you haven’t done it yet, here the part of the procedure that will help you assemble the motor on your heat bed.
- Y axis motor holder
- 1 M6x12 screw
- 1 TNut
- 1 5×5 coupler
- 4 M3x8mm screws
The coupler comes last.
Note the slots that will help you to adjust the position of the motor.
The best is to align the motor with the bottom of the plastic part. The goal here is that the stepper motor will touch the aluminium chassis once this part is installed on the chassis.
Note the location of the motor wire connector on the left!
Keep it free for now.
You can then tighten the coupler.
The motors have all connectors that allows you to disconnect the motor later on
However the X/Z axis jaws requires that these stepper motor wires are placed first
In green you have the Y Axis end stop wire path.
In blue the one for the Y Axis motor.
The motor connector is placed here toward the top of the picture in order to maximise the length of the wire.
Wires then goes inside the Z Axis extrusion profile grooves.
The wire path is indicated here by the 2 arrows and the blue line.
Z axis motor holder assembly
Note the location of the motor connector here.
Again note the location of the motor connector in blue
Place it high enough so that you can insert the motor wires between the motor and the extrusion profile.
The base of the motor must lay flat on the extrusion profiles.
The next step is to screw the blocs in place.
Z Axis screw setup
- 2 M6x12 screws
- 2 TNuts
Help yourself with any tool such as allen key to hold the nut hole aligned with the plastic part screw hole
The base of the motor must lay flat on the extrusion profile. Otherwise you might have some Z wobble.
