hi Dan ,
My Name is Paul ,We have spoken before and I am certain you know more than anybody about the 5T
My version is the GN5 on a Cadillac flat bed i have made many upgrades to this machine...

GN5 has address buttons that allow me to see parameters and diagnostic inputs and outputs .
None of my manuals list a parameter or diagnostic input -output for an M01.
I don't have the original...

Hi Alex,
My name is Paul ,i have probably the last working Cadillac NC100 with GN5 control .
I have taught myself to maintain this unit as it is accurate and i am a small one man shop .
the only...

Hello Travis
I own two two fanuc 5T's which i have trained myself on for rwenty years.
One is a general numeric version of the fanuc called the GN5
Other is a fanuc FX on an Ikegai chucker.
I...

I can copy parameters ,i also know how to make these machines accept very large offsets and i have the hidden parameters 01 02 04 05 for the control.
what year??

The tape reader motor will run when the machine is on . normal
you may have to input a gear range command before the spindle will start.
On the FX25 they are m38 & m39 input start then s500 m03....

Well I found a few moments to just experiment with the 5T and here is some new info.
After enabling the Incremental offset fuction as described in the first post,the control will store large numbers...

I just wondered if you ever saw my post on the method for making the 5T use larger offsets???i found a fix and it allows very large offset values and it works like a calculator adding and subtracting...

I found the problem ,and posted to the fact under 5T5M sub catagory ,
My machine doesnt have a lock ,but kinda wish i did sometimes LOL.
thanks for you consideration.
Peace P

I posted this repy under the wrong Heading but this will alert anyone,please check (UPloading parameters to 5T)
The voltage adjustment pots RV1L,M for VCMDL,M is why the machine could not execute,It...

Man I am really getting to understand this control ,what happened is while trying to fix my first problem ,I created a new one.
Please everyone strive to follow good Trouble shooting practices ,I...

I read most of the problems on here that pertain to the 5T and especially to your replys ,your comment on this matter caught my attention.
i am now having a problem with my control not executing any...

Well I went down to the machines and both of them allow the parameters to be changed from the MdI without any problem .May i assume that If I aquire a main board with the same part number ,i will be...

Man you really command the respect of the guys you have helped on here.
I feel honored to trade a mail or two.
So if I determine that i must load them by tape can it be done thru the Btr or must I...

I may buy another A board for my 5T and I understand the parameters 00,01,02 must be loaded from tape.I have a BTR ,which works great ,,can someone explain the selector positions and keystrokes to...

Hi,all
I have the FX (5T) controller this machine has run perfect for many years but recently it began losing a ready lamp for no reason ,a reset would usually bring it back for a long time ,then...

hi, I new to this site but I have read several psts from guys horrified at the limited Offset capabilities of the 5T ,since I had the same nightmare ,i began searching for the fix ,it is right in the...

Im not sure how to use this site yet,i made a poat about this offset problem and it showed for a day or so then its gone.
Here's the fix for this if it works on all 5t's cool ,if not we have learned...

I commented that I would call T0101 and T0106 I meant that to be T0107
sorry !! there are six front tools and six rear tools so the rear ones start at 07
more soon

Actually Dan Fritzs first comment is the best and most useful.Put a part in the chuck and touch the center and front ,then zero out the readouts then zero return the axes ,the values in the readout...

Thanks for the update ,i know you probably solved this a long time ago but I have just joined this site and I have already found ways to help some others ,Please find my post on the best way to use...

The U value tells the slide to move to a point first,,,, then zero out
you can do z+ some amount,,then command G28 u minus some amount to always get the slide on the correct side of the switch...

The values in your I(x) and J are not correct .
Remember these are in relation to where you start the radius.If X0 is the center of the part (spindle) then the arc should have a positive x end point...

M38 -M39 will change the clutch Clamping

Hi guys ,i have a 5T on an ikegai chucker,and i also screamed when I found you could not input bigger than 9.9999,but I found a fix.This chucker needed to have about 12.5 inches of offset to get the...

Hi, Paul Here ,,,,On my 5T the Rv3 pot on the upper "a" board will only adjust the +5R voltage,,the lug is located just above and to the right of the Rv03 ic
also the Lug for checking the +5 volts...
