hello,
I am new to this forum but reading this for a long time,I like the way this forumn is working to help each other.
I bought a milltronics partner 0-5 (1997) knee mill with centurion v control, last month.
when I first started the machine and did the home, the machine ran very fast to the limit switches, in all the axis, and didnot slow down at the end, I closed my eyes, but every thing went well. I ran the machine for about 3 to 4 hours a day for about two weeks and every time when i did the home it goes fast to the limit switches and do not slow down at the end and also at the tool change it do the same. yesterday it went to the tool change position and went out of the z limit. I tried to do the reset and power shut off but didnot work out, so I moved the hard limit markers about a quarter inch lower and then tried to reset again, i was able to reset it and then i did the home sequence and it again crossed the z limit. so again i moved the markers by taking out one of the two screws and the i repeated the same sequence but now it goes to the marker and almost with a jerky movement it comes about a quarter of an inch away from the marker and goes into emergency stop condition. some times it gives the message for y axis too, y axis out of limit, even thiugh it is a bit far away from y axis marker.
please reply with possible solutions.
thanks.
