Hi all;
I have a dyna myte dm4800 with a mits m3 control. It has been a great machine up untill monday. (yeah i still like it a lot)
Machine was running fine on sunday .came in monday morning and turned on machine and it will not find home position in y axis. x and z home out ok.
the standard home procedure is to set the selector switch to home. then select the axis to home and press the home button. you then do this for all 3 axis.
when you press the home button the axis moves at a fairly fast rate till it hits the home limit switch. It the slows way down till it finds the zero mark on the encoder (i think its the zero mark)
in my case the y axis never makes the fast move. it moves at the slow rate till it hits the software limit.
if i try to home y till it hits the software limit and then home x and z. I can move all 3 axis in rapid and with the handwheel. (the handwheel works all the time even before homing) the position conters seem ok on all axis.
The program will not run . error is no home position
things i have tried:
1. tested home limit swith seems ok
2. tested overtravel limit ok
3. checked parameters most match my documentation. the ones that do not dont seem to be connected.
4. I tried moving my soft limits to allow the encoder more travel did not help
5. swapped x and y encoders no help
6. reseated io board in control and io plugs no help
any suggestion would be helpful
Mike
