Fanuc 18t weird tool offsets, Hwacheon lathe

[mcshaner2k]

Hey guys I've been searching with no results...

I've been running a differant lathe the last few days and I'm pulling my hair out with these tool offsets..

If I call a tool up in MDI ex. T0101 nothing changes on my postion screen. I can call any tool up in MDI and the postion numbers are all the same, relative, absolute, and machine. But in a program the absolute shows the correct offsets.

I can call up T0101 bring it down in the x and touch off on a piece of 2.00 diameter stock. Then in the tool offset screen hit X2.00 measure. My tool should be set right? Leaving the machine as is I then call it up in MDI and the number displayed is way off from 2.00 Its the same deal if I use the tool setter probe.

Could it be reset button not canceling offsets,etc...?

I've ran several other 18 series controllers that didnt do this. I'm sure theres a parameter for this somewhere?? Any help would be greatly appreciated.

on the workshift page in all of the X positions there should be a 0

if it is zero post some pics of your offset/workshift screen maybe that will give us more info
or exactly how much is the position out of position?
also what is the number in parameters 5015/5016/5017/5018? they are reference numbers that relate to the calibration of the setting arm in relation to your machine zero.
and what do you have in 5002, 5003, 5004

5003#6 (LVC) = 0 (offset not cleared by reset)
5003#6 (LVC) = 1 (cleared by reset)

LVC is not relevant here. reset is not pressed.

did you type it correctly?
G0 T0101 then press EOB then press INSERT then press START
the readout in Absolute Position should change.....

Let me try to clarify better.

When I call a tool in mdi it wont show the tool offset on the display page. In auto mode running a program it shows the tool offset in absoule as it should.

When calling a tool in mdi the display reads the same numbers for machine relative amd absolute.

5002. 01010000
5003. 11000000
5004. 00000000

Hope this helps!

[fordav11]

not sure where your problem is but my numbers for those parameters are.....

5002 10000010
5003 11000000
5004 00001000

what have you got at 3115 and 3290?

[mcshaner2k]

Thanks for the reply!

I'm home now but tomorrow morning ill try plugging in your numbers for 5002,5003, and 5004 to see what happens..

Ill get back to you with 3115 and 3290.

[fordav11]

ok compare these at the same time.
My numbers are....

3115 Axis1 00000000 Axis2 00000000 Axis3 00000001 (X,Z, turret servo)
3290 10010000

[sinha_nsit]

After executing T0101, does the screen show T 101 at the bottom of the screen?
The MDI program should only have T0101, no M30 in the end.
I guess you are talking with reference to G54.

Thank you so much!!!

After plugging in those numbers for 5002 5003 and 5004 my display is working properly now as it should.

For some reason my tool setter probe wont work in the x minus. I can push all the buttons with my fingers and watch my offset change except for the x minus button which does nothing. Don't know if this is related or not..

[fordav11]

check parameters 5015/5016/5017/5018. they are reference numbers that relate to the calibration of the setting arm in relation to your machine zero. if you push the X- switch and nothing happens most likely the switch is bad.
