Ok before I start, HUGE spoiler warning for my explanation. Watching the whole series is recommended.
The murder drones weren't actually made by JCJenson, they were made by Cyn using worker drones originally made by JCJ, parts from a machine designed to disassemble workers, and possibly some human remains. The machine she took parts from is shown in either cabin fever or a teaser if I remember correctly
The worker drones on copper nine simply assumed JCJenson sent the murder drones because they went rogue
