This (very long) video details the entire assembly procedure but you can skip to the part you want help with from the list below:
- Surface Mount Resistors 10:58
- Standard through hole resistors 16:49
- Removing solder blobs 23:44
- Current adjustment potentiometer 30:39
- Network resistors 44:32
- Small capacitors 32:37
- Medium capacitor 1:01:00
- Big capacitor (non-standard assembly) 1:10:12
- Terminal blocks 53:27
- Jumpers, connectors, 55:50
power jumper, and vref test point 1:11:10
- LEDs
- Logic power test before main chip (skipped: "don't try this at home")
- Mounting and main chip assembly 1:03:04
- Connection 1:16:11
- Final check list 1:14:53
- Final power test 1:16:54
- VREF adjustment (the quick and dirty way) 1:14:23 and 1:17:32
- Motor connection ( Not doen: To be included in a future video )

Here are videos for two of the options:
- LM317 regulator option to provide +5 logic power from the motor power:
