What the thread found

• Preston offers four digital motor models that work as plug-and-play solutions with their systems: DM-1, DM-2, DM-3, and DM-1X
• The DM-1X is a higher torque version of the DM-1 motor with reduced weight
• Scorpio motors are mechanically identical to Preston DM-2 motors and function as plug-and-play replacements
• Heden digital motors are compatible with Preston follow focus systems and use the same base motor as the Preston DM-2
• Preston digital motors require all eight cable leads to be properly connected for correct operation
• Heden motors unlock when powered off, allowing manual lens focus adjustment without repositioning the motor
• Heden motors use a tool-free gear change system where gears simply insert or remove from either side
• Non-Preston digital motors typically require specific Preston protocol integration to achieve plug-and-play compatibility

Depends on

• The status of the M-One digital motor project was uncertain at the time of discussion
• Some claims about third-party motor compatibility with Preston systems were stated without universal confirmation
• The compatibility information reflects specific user experiences rather than comprehensive testing
