Hi Kev

John, I suspect you've got the optos in the wrong order.

If you look at the traces on the top side, I'd say the top opto is P10, and it's track runs down the outside of the limit switch connector to the E-Stop connector. The tracks of the other 4 optos seem to match up nicely with the Limit Switch connector, and I wouldn't expect the bottom opto track to run the way it does if it was going to the E-stop connector.

Hi m_c


from post 45 "John, I suspect you've got the optos in the wrong order"
you are correct

now I have looked more closely


during the last few days I have installed mach3 on 3 PC's
IBM thinkcentre , Dell optiplex 755 and a PC built using a ASUS H110M-R motherboard

so I should be in a better position to test Kevins mach 3 settings
