[chbot] Maslow CNC, motors and chains

[Peter Ellens]

A few people asked about motors and chains used in the Maslow

 From the BOM 
https://github.com/MaslowCNC/Mechanics/wiki/DIY-Kit-Mechanical-Equivalent-Parts

X-Y Motor/Gearbox/Encoder
ET-WGM58A-1260    291:1 reduction gearbox with worm gear to prevent back 
driving motor, 30kg/cm torque, 20 rpm, 12 volts

Chain
ANSI Number 25, 1/4" Pitch Chain           6261K171 on mcmaster

No idea on chains, if this is common or not.
