Actually the Renishaw design doesn't work that well due to lobeing issues. That is, the break point differs due to the angle of the kinematic support with respect to the approach to the object being measured. That is the reason for the superiority of the Zeiss design. > -----Original Message----- > From: andy pugh [mailto:bodge...@gmail.com] > Sent: Thursday, May 10, 2018 6:50 PM > To: Enhanced Machine Controller (EMC) > Subject: Re: [Emc-users] Zeiss touch probes > > On 10 May 2018 at 23:45, Ken Strauss <ken.stra...@gmail.com> wrote: > > I have no definite knowledge of the Zeiss probes but isn't the > > mechanical switch just to indicate an Estop condition for serious > > overtravel?
