spindle DRO readout in six figures
« on: June 30, 2019, 05:26:32 AM »
have used mach 3 turn for a number of years
after computer crash due to a power surge
have renewed the computer
and the drivers etc
cannot get the spindle index to work on turn eventually have a read out but at 30rpm to 750rpm it is in six figures and does not return to zero when the spindle stops
have no indexing on the mill which works well.
the OS is windows7
all the electronics are from Cnc4you
the index pick up is hall effect switch with one magnet which has been perfect for threading in the past
the wiring to the inputs has been checked
the spindle is switched on and green light in the diagnostics is ok
driver test is excellent
have put in various xml files from previous back ups
the mach3 version  R3.043.062 but have tried older versions as well
now at wits end after about 3 months trying to get a result
would really appreciate some help

have at last cured the problem
changed the computer to an old one with windows XP
now works perfectly obviously windows 7 does not like the index pulse
