I think you have to use G98 feed per minute in this face drilling cycle, or all drilling canned cycles for that matter.
As a rookie, this is my first post. Sadly, it should have been the first place I came. But also a rookie mistake, along with the one that cost me 1 insert and 1 body this afternoon.
Below is the program... know that I have spoken with Manuel and he was no help, nor was my searching the web either... The program runs all the way to the G83 command line. It then DWELLS at X1.50 Z0.25 and does nothing... My rookie mistake, Changed to G87! Thank God that only a body was lost!
Any help with this matter is VERY MUCH Appreciated!
Thank you in Advance!
P.S. I have tried G97, G98, G99 in different fashions, none of that changes things. I have even added the G99 code in the Drill Line. (Got that from an example program from Manuel)

I have tried G98 with in the code by itself or with the G97.
...what cnc control to u have?

...Fanuc varies on codes which Model number ?
0i-TD is what the manual is showing.
According to my training, the G Code System I was told to follow "A Column" versus "B" or "C", is showing NO G95 and G94 being a End Face Turning Cycle. Columns B and C show 94 and 95 being as you said above.
According to the position of your tool at the start of drilling you're trying to face drill off center with a live tool. Why is M74 error detection on? I don't see where you've clamped your C axis. I also don't see where you've started the live tool spindle. 50 thou per minute feed is too slow for any drill. Get rid of all the unnecessary M codes that seem to be tagging along. Make sure tool 8 is registered as a z axis live tool. Get rid of all G99's.
The only M codes you need are:
clamp/unclamp the main spindle
start normal rotation on live tool
M8/M9 coolant on and off
spindle orient if you must before spindle clamp (M19 is an option you might not have.) Use a C axis orient move instead if you have one.
M5 tool off
M30
And why so many M01's? Are you drilling a hole or just thinking about it? :-)
I'm new to lathe programming myself so don't have all the codes for all Fanuc models memorized.
And yes G code system A is likely what you have.
M74/M75 - LT Rotate On CCW/LT Rotate Off (Respectfully)
M19 - C-Axis Control On
M37/M38 - Clamp On/Clamp Off (Respectfully)
Yes I am trying to do an Offset Drill on the Face via a LT. (The speeds are just there, and I don't intend to use those for production.
--- You may be onto something with the Tool not being registered as a LT, BUT I am not so sure. This is the first time I am trying to setup a LT using that versus turned the spindle on and drilling with M03 (Spindle Rotate on CW). I did not set this machine up. They bought it and the man that come set it up is a 44 year veteran, but could have not thought about that. However, I can turn the Drill on with the M74 and it Rotates, so that is why I don't think that is the problem.
I have been thinking about drilling this hole for a month now. Last time I tried this part, I walked away and put it on the back burner. Now I am dead determined, this part is going to run! Maybe that is the reason for the Opt Stops. LoL
Thanks by the way, for the help!
Wow well that's an interesting set of M codes. Not that I'm an expert on lathe M codes. Hardly. I have written some very good working programs but it doesn't happen in a hurry that's for sure.
Curious what machine Year, Make and Model you're running.
Next time you get to trying this, pay attention to the buffer area on the screen. You know... the little area that shows what you're typing and shows what the machine is doing. If you see a FIN (Finish) signal or MTN (motion) and it's just sitting there, the machine has not had all of it's arguments answered to proceed to whatever next step it's trying to proceed to. Make sure the clamping and any other lights that signal completion of things you've asked for are all lit.
If you have a Custom button that is where you'd find the live too setup page. If not just start pressing buttons and see what you can find. Don't forget the soft keys and arrows on/at/near the screen.
Good luck.

...I was wrong about feed code. Fanuc T is G98 FPM and G99 is FPR

I think the gent is rite, try c_ instead of M19
why a Q2500 ?
