Hello to the List, I'm Fabio from Italy. Sorry for my pooor english:) I'm building a nc mill machine together with a pair of friends. Motors on 3 axis are steppers, drivers are MD542, interface is parallel port. I have mounted encoders on steppers to stop the machine on following errors and it works. Now i'm dealing with homing process. I'd like to do home on index of encoders, but i'm having following errors. Home switches are NC, in series and I perform homing axis per axis. Conventional homing is fine, if I activate home on index I have following error on the axis being homed. For example on z I have home at 180mm, home offset at 190 search vel 5mm/s latch vel -.2 final vel -2, rapids are 16. Tried also final vel 2. If I raise ferror and min ferror to 100mm I don't have following error but behaviour is strange: the axis goes to switch at search speed, then goes down off switch at latch speed, then for some reason accelerates axis to some high speed for about half a second and finally goes to (wrong) home position at final speed. Since the machine is about 30km away now I'm testing motors on my bench and I'm activating home switch by hand. I don't want to write a huge message, how can I attach my seutup files? Thanks, Fabio.
