There was a corroded leg on the eprom nearest the backup battery, I replaced the leg with a strand of wire and also the tantalum capacitors needed replacing.

Just to follow up, I got this lathe running. I repaired the FX784-9 board and also had to replace a servo and spindle drive.

Hi, I hope you can help.
I have just purchased a QT8 that wasn't functioning. When the NC is turned on all I would get are zero's and a blank screen.

I replaced all 3 batteries (they were dead...

Ok, Just wanted to give an update to this.

I received a phone call from a chap in Melbourne, Australia. That had a similar problem to me on a Chavalier VMC with a Fanuc 0mc controller.

Yes it is a Fanuc 0m.

Hi, Yes sorry that post was not clear, I key in 5 input, 5 input, then press the "WRITE" softkey. All I get is the flashing "**MISS SETTING**".

Hi, I have a 1992 MV40b that I'm having trouble setting the tool positions on. When I'm in the tool settings page the manual says to put pot number in MG and tool number under T.
Example MG 5 input,...

Hi everyone, I just picked up a Mori MV40b with the Fanuc MFM4 controller and I was told that it didn't have the rigid tapping option. Is there a way I can check if it has it and if it doesn't can I...

Hi, can you elaborate on why you would buy the candcnc unit over building your own, $750 is a fair chunk of change.
