Hi Some time ago, upto 5 years when i first started by build i bought a set of ball screws and nuts from a company in devon as what was in stock it is a 16 x 4mm ballscrew with an ISEL ball but, great everything wen well and i have since been chcking out swarf.
Today however the connector to my limit switches fell out and i atempted to drive the spindle about a foot past x limit ............OUCH!!!..........and........ ~@**!!........ i split the nut, now who can supply a new or second habd nut to fit an odd size ball screw................oh wow is me, next time i will lock the connector in
