Hi, this should be a problem with the spindle encoder, it's possible to break the belt between the encoder and the spindle !

I tried both G96 and G97 and no luck.
Re: 18-T on a Hardinge conquest T42 stops on the G01 without any alarms.
Hello TassScott,
Is this the first time that the program didn't run ?
Is this a "new" machine for you ?
Is the progam code correct ?
Sometimes older lathes don't run the G98 on the spindle side, but only in combination with the live tools / C-axis.
Did you run the program earlier without problems on this machine ?
What happens when you add the G99 at the first lines of your nc-code ?

Hello Heavy_Metal,
Yes this program runs fine on any other machine. This machine won't run any program past the G01 in G99. The machine has live tooling and will feed in G98 just not G99. This machine is new to me, been sitting in an air conditioned room for 3 years. Just trying to get it going. I have put G99 in the beginning of the program to be sure It was in the correct mode. It's just a simple program to bore jaws. I have several parts I want to run on it but none of them go past the G01.

Hi,
I assume when you say this program will run on any other machine that they are the same Hardinge Conquest T42.
Is there no other sample program in the control that you can try ?
In any normal 2 axis lathe theres no G98 / G99 it's always inch/rev or mm/rev. G99.

Hi,
No not the same Hardinge conquest t42 but a daewoo with the exact same control and capability. I did try to run the three programs that were in the memory already but they only ran the part of the program that was using live tools but of course that's in G98 inch/min. I'm starting to lean towards the encoder or a cable being the issue. I think I've pretty much crossed off all of the stupid mistakes I could have made in the process.
These are some of the Active G codes listed on control when it stops.
G01, G99, G96, G50, G80, G40, G23, G54 there are some more but these are the ones I'm usually concerned with.

Re: 18-T on a Hardinge conquest T42 stops on the G01 without any alarms.
could be related to spindle feedback ,is the spindle showing the right speed?
Re: 18-T on a Hardinge conquest T42 stops on the G01 without any alarms.
Hi TassScott,
You said that you put the G99 at the top of the program, that's whats normal.
When I look to the Hardinge T42 Fanuc 18-T manual in all examples they put it after the G50, G96 or G97, G41/G42.
Not every Fanuc-18T program will run on any other brand machine with Fanuc 18-T, sometimes you need extra codes.
In the example they put the G99 on two places whats new to me, normally only when you change from G99 to G98 and back.
Maybe it's still a progam code error and not a hardware problem.

Hi , I have the same problem with my conquest. Have you sorted this somehow?
Always program stop at block with g97 , g96 and dosnt go through G0 and G1 when is on G99 but when change for G98 and switch spindle off program run.

And also:
In my conquest t42 ( fanuc 18t ) reverse spindle for left hand tools is M23 ! not m4. In my machine m3 and m4 dont work. And I steel don't know how to switch on spindle forwards. Please help with both problems.
