General Mach Discussion / Re: mach3 turn threading issue

thanks Robert

i changed from a proximity switch to a hall effect and magnet .
i have a 12mm magnet on about an 100mm radius on a disc
before i had an m8 bolt head .

im just trying to find out if the problem is using uc400etc or the index detection isnt good enough  my max rpm is 2500

not all good now the thread looks bad .
the mach3 threading pdf said it needs the spindle feedback in sync modes boxed checked.
is this correct?
are there any other configuration settings that need to be input
thanks

hi   i still have the same issue .i changed the sensor to a hall effect and the index light flashes on diagnostics page. rev counter  works ok and i can calibrate spindle rpm.

(THREAD1)
N28 M6T0707
N29 G54
N30 G95
N31 G97 S500 M3
N32 G0 X45.4 Z5.
N33 G0 Z7.5
N34 X23.6
N35 G32 Z-24.8 F1.5
N36 X24. Z-25. F1.5
N37 G0 X45.4
N38 Z7.5

it just sits waiting on the g32 line.
is there some tick in the box im missing .i only have input for index , left timing unabled or is itsomething wrong with the code

forgot to add i use a UC400ETH Motion Controller

thanks

hi rich

the index debounce is already set to 10 , i tried 1  and no difference.

the feed per rev  (1.5) was flashing 1.5 /off

when looking at diagnostics  the  index flashes if i turn it by hand  ,its intermittent at high revs

the true spindle speed registers ok

i have a npn  proximity switch  picking up a bolt head on a disc on the spindle
will this provide a good consistent signal

cheers

« on: September 08, 2019, 02:22:07 PM »

hi everyone
i have just started to turn a thread with my mach3 turn lathe . i have an issue . the rev counter works so i guess mach is receiving the signal ok.

when i started the program using either g32 or g76  . it moves in to position to cut the thread but just sits and waits doing nothing.
i would guess its waiting for the rpm signal . i presume i dont have some of the settings configured properly
can anyone help

cheers
