***Problem solved, I had the machine turned on all night and the next morning G84 was working again, No changes made to the code or to the machine, It just worked again, The problem is a faulty mainboard***
Hey fellow CNC-folks!
I've got an old Johnford VMC-416 mill (1986?) with Fanuc 0M as controller,
So my big problem is what the title says, G84 has completely stopped working, I get Alarm 014 as soon as the machine is about to start tapping, The code looks exactly the same as it did when G84 worked. When i check the Alarm 014 in the manual supplied by Johnford it says something about the K-value being too high of what's allowed, However, I don't use a K-value and i haven't done it before either (The k-value can be used when you use G91 for repetations or something like that, but i use G90 so i shouldn't have to use the K-value at all, and as i said, It worked just fine before), However i did try using the G91 version with a K-value in the tapping code but with the same result.
I've searched the net for a possible fix but it doesn't help that much, My assumption is that a system parameter has been changed or something is wrong with the board, The later is what i suspect because i haven't touched the system parameters ever and they seem to be intact, But with these older machines you never know
Some misc information:
-M29 does nothing (Seems like some newer controllers need this code to be able to start tapping)
If i check the G-code list in the machine there's a G63 called "Tapping mode"
G63 is used for tapping in Fanuc 21 if im not wrong?
"N...G63...Z...F"
Just for the hell of it i tried using G63 but nothing happens, No alarms, no nothing so i got no clue why it's included in the machines G-code list.
Anyone been through this before and know what i need to do? The tapping is the last operation on my parts and i'd rather not have to tap 250 holes manually, hehe
Oh yeah, I've done the "shut down the machine completely, wait a while, Start and try again-part" a dozen times and it doesn't work either,
I'd be really thankful for some help here
