Fanuc 10M problem with work offset

[Swemill]

I have a strange problem on my VMC with Fanuc 10M control.
If i interrupt the program (pressing reset), and start it over again - from the beginning it reads the "workzero" from where it stands and not from the position where i have set it in G54...

Must i really do a zeroreturn in all axes everytime before i run the program (if i have done any editing)?

I have tried with different settings on the "ABS" switch.

The even more strange thing is that it's sometimes only in the X-axis that it runs from where it stands and it follows G54 in Y and Z...?

Does maybe 10M controls require anything more in the program to get this to work (as it does on newer controls) or is it me that does something stupid?

A program example how i usually write below:

%
:6666
G80G40G54
G0G90G43X50.Y-40.Z10.H15S2500M3
Z2.
G1Z-15.F1000.M8
G1X-200.F270.
G0Z10.M9
G91G28Z0Y0
M30
%


Thanks in advance!

Swe mill,
I have reorganized your program a little should take care of any problems your having, just check the code assume your using tool #15 and have placed the return to referance postion at the top of the program this way when ever you start the program the machine always homes all axis. Just verify the code for the tool change to proper tool. Assume your working in Metric mode, added that code too.
hope this helps!

Ok, thanks for your reply ksc!
Yes, i always does like this on my 3M control (with only G92) but i didn't thought it was necessary on a 10M.
Offcourse it will work but if i for instance should start a program in the "middle" - it would be nice to not have to read this start / zeroreturn every time...

Anyone that know if 10M require this or if maybe this could be "adjusted" in parameters?

I wonder how it is on the 10T. I [Dry Run] parts before I go to actually machine stuff. Then again I hardly ever pause programs or start in the middle.

[Swemill]

Ok gbowne1, i understand you but if i run a program, does a little editing to make program run better and then maybe only need to run one of the tools again... Then it's nice if it works to start "anywhere"!

On my 3M control i in this case run from start in singleblock, then jump foreward in program to where it was ment, but was hoping to skip this on the 10M control!

It seems that it's not good to press reset - or do any movement in handle / jog because that mess up the controls position / work offset!

Anyone else with this problem, or with any info about this?

[gbowne1]

I nearly always use a toolpath verification software [VeriCUT] so I can eliminate crashes.. along with my dry run procedure. I never have found a very good, or safe.. way to do what you're trying to do.

I never make any handle Jog moves while I've restarted the program. From what I have noticed too, is that does change the values.

I've not had a broken tool crash so I've never had to re run a program from where it left off when the tool broke.

Anyone finds a good safe proceedure for doing so let me know.

Stepping in single block is ok.. never had any problem with that.. especially while editing.

[Swemill]

Ok. I actually often do handwritten programs and there it's good to be able to edit meanwhile testing the program.
It also doesn't have to be a broken tool but a compensation that needs to be adjusted and re-run.
At my work we has O-M controls and newer and there you could edit and start where you like without any zeroreturn! Guess i have been "spoiled" because of that...

However it's good to read that "From what I have noticed too, is that does change the values", because then it's proberbly not me that does wrong and 10M controls need this!

Thanks!

Swemill,

I also have a machine with a 10M that requires referencing if stopped mid-stream. It didn't do that before it lost its parameters and I've been unable to find the parameter to correct it so we've just lived with it. If you find anything about this problem, I would love to know as well!

Regards,
John

[Swemill]

Ahh... This could be a parameter issue! Thanks, i will search for this info. I dont think my machine has lost any parameters since it was new but it maybe never have had it this way either...

Thanks!
