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.
Wanted -- Things I'm looking for
- Documentation and/or software for the Kumagai KP422 I/O card (I expect this will be in Japanese – this is fine!)
- Source code for the ECM control software is apparently “in the wild” – this would be extremely useful!
- Spare nozzles – any for the ECM series machines (ECM93, ECM95, ECM97, ECM98, ECM99, ECM Luna) will do.
- Any documentation, software, etc. for the ECM series machines which I don't already have
Please email philpem@gmail.com if you have any of the above
Configuration and specifications
- ECM97 Console variant with Cyberoptics LaserAlign HD component alignment system, top-down teaching camera and automatic fiducial sensor (EYE sensor)

- Mix of 8mm, 12mm and 18mm feeders
- Vibratory feeder
- PCB conveyor
Specifications according to this page:
- Accuracy ± 0.1mm
- Air supply 60psi (4.14bar, 4.22kgf/cm2)
- Min PCB size 2 x 2 inch (50 x 50 mm)

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:
- Panasonic PANATERM servo driver configuration software
- LaserAlign LA_VIEW software configured for the LaserAlign HD
