I bought a NEODEN 4 PnP machine a few years ago. The mechanics of this machine is reliable, fast and precise.
The bads: Software, WinXP, documentation, crashes, feeders and support.
After producing several batch of small series electronic boards, I arrived at the conclusion that this machine cost me too much money in man-hours. I decided to replace the bad: feeders, software and electronic (not the motors drivers) by the goods: custom made DIY feeder, OpenPnP and custom electronic board.
This feeder is the first part of the work in progress.
