I shut my power off to two old machines like this for weeks at a time with no trouble. Maybe just a coincedence that the batteries got low at the same time. One thing for sure, always change the...

Found the problem.
When I changed the "Handshake" setting from "Hardware" to "Software" everything worked fine. (the instructions said to use "Hardware")

I am setting up my lathe with Fanuc OT controller primarily to send programs out to a PC and save it. After a day of adjusting baud rates, etc. I seem to have the machine and PC talking to...

You would be better off getting geometry offsets and workshifts. it makes a huge difference to setup times :-)[/QUOTE]

Could you elaborate? I'm not sure what you mean by this...
Thanks!

Because the servo motors have absolute encoders, the machine zero is always the same, it never changes. Everytime I boot up the machine zero is the center of the turret (x) and the front surface of...

Thank you for this helpful explanation and .pdf.
I'll try it out on Monday.
Now I'm wondering one more thing related to this...
As I mentioned, the lathe has absolute encoders. The machine zero...

I have a 1989 two axis lathe with absolute encoders, Fanuc 0T Controller. It uses G92 for the coordinate system and I'd like to know if it can be changed from G92 to G50? I get an error alarm if I...

Thanks Al. Maybe that's what happened with the encoder. I can live with the new home position if I know I didn't hurt anything and that it's going to stay put at this new position. Sounds like...

I recently had a servo alarm in my x axis that was traced to a broken wire on the encoder cable (Fanuc 3T controller on a Wasino LG-81) that fried my drive. Today I replaced the cards and got the...

This is a 2 axis machine and now the alarm won't clear even when I power the machine off the then on. I'm inclined to think it's the drive. Especially since I got an alarm in both Z and X axis...

Just got the same alarm while doing a zero return in the X axis and it won't clear even after powering off/on.
I'm dead in the water!
HELP!!

Thank you for the helpful reply.
It does appear that I have a dual axis drive. Of the two Honda plugs at the bottom, X is on the left and Z is on the right.

I have confirmed that the alarm is...

Ok, Got the alarm again.
Found a red LED alarm light labeled "TGLS L"

Wondering what kind of problem this is.
Thanks much

Thanks for the reply.
The only way to reset is to power the entire machine off.
The only other info I have is what is displayed on the screen "Servo Alarm 02 (VRDY OFF)"
How do I find the Servo...

My old Wasino LG-81 CNC lathe w/ Fanuc 3T controller. It started giving me a servo alarm today. Code is #02 which says VRDY OFF, Velocity Control Unit has Turned Off.

This seems to happen when...

Hello,
I have a Wasino LG-81 Lathe with Fanuc 3T controller. Works great for the few parts I turn out with it year after year. Trouble is the limited memory. It is maxed out at 8191 Characters. ...

Thank you for your input. I wanted to follow up on how this was resolved. I ended up returning the bad alum. and getting another piece from a different lot. Started machining it today and it made...

I regularly turn out parts on my CNC from 5 1/2" diameter aluminum, 6061 T6511. Today the parts from a new batch of this stock would not make a good finish -looks a bit like chatter marks but its...

It was indeed the F2 fuse located behind the spindle amp.
Thank you very much for the help,
Jeff

Hello and thank you for your helpful reply.
The alarm appears to be on the "AC Spindle Servo Unit"
Type No. A06B-6044-H009
Mfg No. K54-08250M

I have checked all the obvious fuses but would be...

Hello,
Got up early on this Saturday morning and started machining with my Wasino LG-81 CNC Lathe (Fanuc 3-t controller). In the middle of the first cycle, we got a area wide power failure. It...

I have a 1985 Wasino LG-81 with Fanuc 3T controller. I believe the motherboard just bit the dust. Everything was working fine last time I shut it down a few weeks ago. Now, the monitor will not...

I have a fanuc 3T controller. It is a gang type lathe. It uses the old style G50 for the program zero for each tool. ...Not a big deal. The problem came when, in an effort to squeeze one more...

Here's my problem...
On this G71 cycle I need to have the tool be farther away from the part each time it rapids back to the starting point in the Z axis. I am stumped and have tried adjusting just...
