Thanks Brett.
Hi Monty, Brian, I have just run tests homing individual axis as suggested. First of all I have to say that, on my machine, when I click 'Home ALL Axis', it will often get stuck on the first try or very soon after it - like 2nd try. That said, I have now homed each axis INDIVIDUALLY 50 times in a row without a single hitch. BUT - as soon as you start clicking the same home button before the axis is finished moving, it will get stuck when it hits the switch and will just sit there. You then have to reset and back off. In other words, if you click the axis home button few times in a quick sequence, it will get stuck. Hope this will help Art in locating the problem.
Regards,
Ivan
