This step will show how to download the custom patterns from the knitting machine memory to your computer. This is just for the 'custom' patterns, it wont download the 'built in' patterns that are shown in the manual.
Plug in the cable into the back of the machine.
The emulator also makes a handy file-01.dat file to make it easy to preview the patterns using dumppattern.py (see the next step)
We'll need that file-01.dat file, so make a backup of it somewhere else for safekeeping! That file contains all your patterns.
