Hello All, I want to use my Fanuc 18T lathe control in what Fanuc calls 'G-Code System B'. Upon reading in both the operator's manual and parameter manual all I can gather is I have to change ONE parameter setting, i.e. 3401 bit 7 = 0 and 3401 bit 6 = 1.
As far as I know the control was set up for 'G-Code System A' as these two bits were cleared (or zero). I changed this parameter setting before I made the first chip on the machine so I cannot attest to the control behavior before changing this paramter, but when I use a G90 to specify absolute coordinates the control complains about not having a feed rate. Remove the G90 and the control is happy. It also accepts a G50 for spindle speed clamp with no issues. In 'G-Code System B' the spindle speed clamp code would be G92. What am I missing?? Best Regards, Wayne.
Gotcha Snowshooze. It took a while for me to get used to the 0 bit being the first bit (not bit 1) and always on the right as well. The funny thing is the control seems to run okay as is. I have ran only one part on it thus far and made about fifty of them. Still trying to get used to the work shift function so I can understand it well enough to explain it to someone else. I seem to get lucky poking numbers in and using the dry run function with a low feed until I get the number that works. Not knowing what I just did is unnerving to say the least!
I left a thread on here hanging because I don't want to just blabber on like an idiot about what I've done to solve my problem. I just read another thread that was started today with complaints about folks leaving threads open ended.
I know that's aggravating. Anyway, I would like to be able to put this to bed in my mind so I can stop worrying about a horrific crash later when I load up a different program because some parameter isn't set correctly. Then hopefully I can back up to the previous problems and solve those. I don't think I've ever had anything snow ball like this before! Gotcha Snowshooze.

Do you mean that you resolved the issue setting the control to use G Code System B, or that you find its OK using G Code System A? Overwhelmingly, System A is used with lathe controls, and the Fanuc Manual refers to that System when explaining the various functions.
Accordingly, if you have questions regarding the functions of a Fanuc lathe control, you will find more who have a knowledge of System A than System B or C, and therefore, a greater knowledge pool from which to draw. Further, finding answers in the Fanuc manual will be easier when using System A as well Regards, Bill. Hi Wayne, When you say 'The funny thing is the control seems to run okay as is.'

In my mind the problem is NOT resolved. It's my belief G-Code System B has been selected. But, the control does NOT behave that way - or at least it seems. What has me puzzled is when a G90 appears in the program to select absolute coordinates (G-Code Sys B) the control complains 'No Feed Rate'.
As a work-around I simply deleted the G90. It's my understanding the control is in this mode after power up and there are no G91 codes in the program. There are no incremental moves either, i.e.
I understand what you're saying about most people using G-Code Sys A. I may have to revert back and re-write some programs. Joe, It's a line of g-code that puts the lathe in a known state: N01 G90 G80 G40 G20 Delete the G90 and the control is happy. I'm beginning to wonder, since Bill has brought up the point, if Fanuc never really proofed the firmware because few if any people want to use anything other than G-Code System A. Therefore, any problems that may lie in the controller firmware never got ironed out and the easier solution was to stick with Sys A. BUT, I'm not 100% satisfied that I'm not goofing up somewhere.
I have the manuals in.pdf form (and I also printed/bound them) and I can use the search feature to search the manuals. Using that PLUS actually parsing through by hand I cannot find any other parameter(s) to modify other than 3401.

My apologies everyone. Perhaps I should have included the line of code above in the beginning, but I honestly didn't think it would have a bearing on the topic at hand.

The example block above will definitely give you grief if the control is using G Code System A. This is your Start Up Default block where you're wanting to select Absolute Mode, but the control is interpreting it as a Canned ID/OD Cutting Cycle. To determine for sure what system is selected, with the axes slides in a safe position, execute G00 W-2.0 in MDI mode. The Z slide should move -2.0 inches with System A selected. The parameter settings you have should have selected G Code System 'B'.
System 'C' is an option, but Systems A and B should both be available. Check on the control's specification sheet to see what options have been included. Regards, Bill. Bill, The machine manufacturer's documentation, if understood properly, states Sys A and Sys B are standard items. There is no mention of Sys C in this documentation. Upon reading The Fanuc control manual one would not think the three systems were 'paid options'. I will give your 'acid test' a go, see what happens and report back.
Ox, I hear what you're saying about mixing abs and inc modes. I have some part time guys who, like myself, are milling oriented. So, my thinking was to minimize the g-code differences. Since their head isn't in this all the time like mine is I think I may have fewer possibilities for a crash that scraps this little lathe.

Maybe I'm missing the obvious there as well. I also thought once we became more acquainted with the machine I maybe decide to switch back to Sys A. However, this seems to be more than simply flipping a bit to change G-Code Systems. I have some part time guys who, like myself, are milling oriented.

G92 needs not be used, as the Z Work Shift offset will take care of the varying Z Zero, and the X Zero never changes. G50 in G Code System A is used to clamp the spindle speed in Constant Surface Speed mode instead of Scaling Cancel in the Mill Control. As you can see, there is not much to deal with, and a big advantage, as Ox points out, of being able to mix Absolute and Incremental addresses in the same block.
Regards, Bill. Bill, So, I suppose to conclude this discussion the bottom line would be although Fanuc states in their documentation you may select from three G-Code Systems the parameter change must accompany a monetary exchange.
Would you agree? Thanks, WayneHi Wayne, I've seen lathe controls supplied without junctions such as the Mult Repetitive cycles G70 - G76, those functions that most regard as standards, but are in fact options. System C is an option for sure, but A and B, in my experience, are normally both available. One System would have to be supplied for sure, otherwise you wouldn't have a functioning control. I would be asking the question of the supplier, if its a new machine and Fanuc if not.
