MDC ECM97 pick and place system

I bought this machine in 2013 to assemble DiscFerret PCBs. It's turned into a project in itself!

The control PC is an old Pentium PC, with a Kumagai KP422 motion control card and an MDC custom 16-bit PC I/O card.

Unfortunately MDC Co. now appears to be out of business (as of late 2019), so parts availability is precisely nil. I am looking into the possibility of machining new nozzles.

Software

I have a complete hard drive image of my ECM97's PC, with various versions of the ECM software. I am working on extracting the necessary parts of the ECM driver software.

The ECM hard drive image contains the following additional tools:

Nozzles

Servo drive serial cable

To configure the servo drives or retune them (e.g. to fix control loop instability), you need a Panasonic DV0P0790 serial cable kit and the “PANATERM” software. These have not been available for some time, but the cable is easy to make, and PANATERM is easy to run on a DOS PC.

Connectors

Mekko was the UK sales/support contact for these machines, but no longer supplies them.

Manncorp sold them under alternative names, but will not provide any support without a service contract.
