The motors to the drivers
9. CONTINUED - Use flux.
6. wrap the second 18awg wire around the 14awg wire.
Use my calculator and the procedure in the video to calibrate your steps per mm. Doing this fine tunes your CNC machine's movements. Jog the spindle a short distance first to make sure you are close before sending it a longer distance. you do want to eventually do it as far as you can safely to get your travel as accurate as possible.
(INCLUDES POSITIVE WORK SPACE OF VERSION 1.1f)
The 24vdc fans cooling the drivers will have to be spliced into the 24vdc main to TB6600 drivers.
The homing/limit switches
This is only if you are making your own with the files on the Demon Shield TM page. The Demon Plate TM, if purchased, comes already glued together and includes hardware.
The Demon ControllerTM can be used with the X-carve post processor or any of these. There are 3 post processors that include M7 and M8 activation. They will deactivate at the end using the M9 command.

4. wrap the 18awg wire around the 14awg wire.
2. Interlock the 14awg wire and the first piece of 18awg.
For the X-CARVE, I set X and Y axis at 8x micro stepping (S1 OFF, S2 ON, S3 OFF). Z axis is 2X micro stepping (S1 ON, S2 OFF, S3 ON).
8. Twist the 14awg end.
Controller setup instructions
7. Repeat until all 4 18awg strands are on the 14awg.
12. The second piece of shrink tube goes over the 14awg wire only a little, the solder joint, and the four 18awg leads.
Loading GRBL and Testing
11. The first piece of shrink tube goes over the 14awg wire and solder only to build up a little bit of thickness.
The crimp on connectors that fit the larger wires and power supply terminals are the BLUE #4-#6 STUD 14AWG TO 16AWG CONNECTORS
You need to change your dir port invert mask ($3 in GRBL settings)
put in your current $3 number, click the button next to the direction the axis DOES travel. it will tell you the number to change it to in order to make the axis travel the correct direction.
For the CNC4NEWBIE Newcarve, I set all axis at 8x micro stepping (S1 OFF, S2 ON, S3 OFF).

Gluing the Demon Plate TM
Installing the Demon Shield TM
Thank you for purchasing my Demon Shield TM ! You path to an easy, affordable, yet powerful controller just got easier! The following videos are a step by step demonstration of how to assemble a Demon Controller TM with the Demon Plate TM. It will also show how the self 3D printed parts get installed. The Demon Plate comes with the Arduino Uno mount. The other parts are only available for you to 3D print at home. They do, however, come with the Full Demon Controller TM.

10. The solder should be sucked into the wires as shown. you should see the strands, not just a glob of solder. you will need a powerful solder gun, not just a solder iron. I use a 140w gun.
13. A third piece of shrink tube gets centered over the other ones and ensures no points of the solder joint will poke through.

Place post processors in the following directory:
For 3 amp motors, I set the Current at the 2.8 amp, 2.9a peak setting (S4 OFF, S5 OFF, S6 ON).

|Distance sent (mm)|
|Distance traveled (mm)|

3. Twist the 18awg wire only and slide it left towards the 14awg wire's jacket.
the driver cover
5. Interlock the second 18awg wire next to the first onto the 14awg wire.
The EAGwell 24vdc power supply covers should fit the original Inventables power supply.
1. Strip about 1 inch off the 14awg wire. about 1/2" off the 18awg wires.
