I recently converted my CL300 mini lathe to 3phase/inverter driven. I now have two old Seig control boards, which are both faulty I'm afraid. I can send them FOC to anyone in the UK who wants them, either to repair or use for spares. One is type FC200JF/230v. The second is type FC250JSMD. If no interest is shown, they will join several obsolete computer mother boards, which will shortly be taken to the tip recycling centre. PM me if interested.
