Just played with few old DVD had been given.
Once stripped the guts to the centre frame and stepper drive connected up to Arduino CNC shield.
DONT do what I did and pull off the connection on one of the stepper motors.
Donor DVD, old Woodpecker 3.0.2 board (faulty).
The sharp eyed in the last image might see an HP ESP120 and some bits for a W6PQL SSPA and some R3KO bits I am building for another.
