There are small oily marks not scratching the metal, from the edge a bit inwards so I guess angle is correct. > But one alternative might be to form modelling clay around a stick on the > end of a holder with no pull stud, to see what shape it pushes the clay in > to. Tried with wheat dough but replaced salt in receipt with oil as I think machine oil is better for machine than salt due to corrision, did not get it to work. Tried to grip the end of a cable and that did not work either, could see no marks at all. > (And then when the clay gets stuck in the petals you have no choice but to > strip it all down for inspection) > > It might be easy. On my home-made drawbar the entire thing just lifts out: > https://youtu.be/pxrzJ_KfcQ0?t=23 Removed from top, there is some kind of oil cylinder releasing tool but failed to get further down , a pin sticking out not possible to move, guess there is a spring somewhere further down. I tried anyway and think angle is OK. For some reason touch off did not work in the Y direction in version I had, tool running in air behind part which was really annoying then I at last get it inside. Tried new version then I got back to office and there it works in simulation so I am pretty sure touch off will work once I get back to workshop with an updated version. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
