I wanted to pop in and post a quick update for those watching this thread. Since posting last, I was able to get my soft limit issues resolved for the most part. I found the parameters I needed to a...

Thanks for the info everyone as well as the contact phone Bill. I wont be home for most of today but I can give you a call later tomorrow or Monday if I can't get it figured out before then.

I have recently acquired a replacement master board for my Fanuc 0ma control, which died on me a couple months ago. I installed the replacement board, powered it on and it seem to come back to life....

Seems like we all tend to agree on going retrofit vs repair. In fact, the machine is actually a retrofit to start with. Its a 4000lb knee mill, outfitted for cnc in the late 80s made by a company...

yeah, that is what I was thinking too. Being that I do make a little money with this piece of iron, the wisest decision would probably be to just get it turning chips again asap vs. turning it into...

Quick update for those still watching this thread. The Fanuc tech came out today (for a hefty fee of course) and confirmed my fears. It would appear that My Master controller board is...

Thanks for the info Dpuch, I actually have considered that alternative but as you put it, its always a calculated risk when the parts are coming anywhere other than the manufacture. Fanuc has quoted...

Thanks for the Info F-bu. You bring up a good point about having faulty E-proms. We checked the voltages off the main board test posts as well as the power input unit I believe its called. We also...

A quick update for those watching this thread. A tech came out today to diagnose the mill and it would appear that there is a hardware failure in either the GPU card or the main board. As many of...

Sounds like its worth a try, the only problem I see there is that I don't exactly know how to back up the parameters. Especially considering that it would require booting the machine up to a point...

Ok, So I got a hold of a local service tech in my area and he gave me a few short walk through procedures to try over the phone, so hopefully I can update those watching this thread and further...

I own an older cnc milling machine with a Fanuc 0ma controller on it and earlier this morning, the controller appears to have partially died. When I say partially, I mean that I can hear the machine...

Heres the update since last post,

I checked the diagnostics menu and found that line #26 corresponds to the keypad buttons. I went through all the buttons all over the controller, which all...

so I finally got some free time today and spent a good portion of the day on my machine. It now would appear that #3 has come back for the time being but now my 1k feedrate is still dead and my #2...

thanks for the tip Phil, ill be sure to give that a shot the next time it acts up... and thanks for the clarification on the lingo Al :).

I'm a young guy who's doing the full time college thing,...

I don't know if this helps or not but today, everything was working again and then midway through the day, the #3 starting acting as before. I got mad and then hammer fisted it the right under the...

Thanks for the input Al. I haven't posted sooner because the problem tapered down briefly. However, today it came back stronger than ever, so something needs to be fixed. It would seem that my #3...

I was thinking about your post Al, and if I understand what your saying correctly than I should be able to go into my diagnostic parameters and see a bit value change when I'm pushing a button which...

Hi Al,

I'm really really hoping that a loose connection is all it is but wouldn't it be the case that all the buttons would be malfunctioning if it were? How do I know what to cable to check? ...

I have a Fanuc 0ma controller and its developing a new problem. I just came in from the garage quite discouraged because it would seem that 4 or 5 of my buttons decided fritz out. By this, I mean...

funny way to put it fighter but its very true. I think their about .001 tall and they look so much worse. I'm not exactly sure how to radius the face mill either. Can someone go slow and explain...

Electronics failure is a possibility but I really don't think its likely in this case. Until recently, I haven't been homing my machine at all and I probably have tripped the over travel alarm 20...

First of all, I want to say thanks to everyone helping on this thread. So now down to business. Dan, I have seen that ABS button on my machine an wondered what its all about but I've always left it...

I tried to home the machine and for some reason the soft switches trip before the control panel lights up indicating that its homed. When I first bought the machine this was giving me trouble then...

Thanks dertsap, that helps allot. I read through the link and ill be sure to get into the habit of homing but I am still a little confused on something. Whenever I boot up my machine for the first...

actually.....I did not. Now this is going to sounds really dumb but I haven't really been using the homing feature at all because to be honest, I have no idea what it does :).

Yeah I know, I'm...

I have a Fanuc 0ma controller built in 87 on my knee mill and I just experienced a new problem. I only have a couple weeks experience so far, so it seems like I'm constantly trouble shooting new...

So I've been doing some experimenting with various end mills while cutting my aluminum and what I've found so far is that I seem to be breaking the smaller bits quite more than I would like. I like...

Thanks,and great info guys, Ill be sure to check into those next time I'm placing an order. I did somehow end up getting my vice to within about .0015 over my 6" jaws. I actually used an edge...

thanks for the info. I might be reading into the picture too much, but it looks as though the probe of the indicator actuates by a swing/lever rather then a push button style, which I previously...
