Loco number plates for the T3 are
not available in the model engineering trade. I had a sample of a real
shed sign, which was the base for my loco plates.
The design was done in Solidworks.
To make these, I had to buy and convert a milling
machine to CNC. A model engineer gave a tip to look at
http://www.impulsecnc.nl. This supplier gave me good advice in how to build a home-made
CNC milling machine and which components were needed. I started out with the
basics: power supply, drives, USB-CNC controller and stepper motors. A cabinet
was bought second-hand.

The wiring-up was done according plans.
Simply follow the given instructions and connect all the pins of the controller
board to the drives and power supplies.
A setup had to be made to connect the
motors to the spindles. These are stepper motors of 4.5Nm connected to ball
screw spindles with an pitch of 5mm.
Setting up the USB-CNC controller required
some jumper settings. On the drives the dip switches had to be set to a given
motor Amp and micro step.
