Mazak QT 250 Nexus Computer won't load Mazak Software (Cannot Find T640Eye.exe) Help

I recently purchased a 2006 Mazak QT-250 with a Nexus 640 control. I had it shipped from Ohio to Oklahoma.
So when I try to power up the computer for the first time nothing happens. I open the control cabinet to investigate. The power supply board and the processor board is unplugged and just hanging in the cabinet behind the plastic housing. I got all that plugged back in and reseated all the ribbon cables and any connector I could. After that, it started powering up. It gets a "Cannot Find T640Eye.exe" error. Windows boots up and the Mazatrol screen starts to load then it errors out. I called Mazak, they recommended replacing the hard drive. I called Mitsubishi,
they recommended replacing the hard drive. So Tuesday I ordered a new hard drive ($1300... ouch).
Today I installed it and I still have the exact same error.
I spent an hour and a half on the phone with Mitsubishi. I hit the input button and a Window pops up with Bus Console screen loads a bunch of program looking text. Now they recommend bringing in a service technician.
Has anyone out there had this issue before? What did you do to fix it?

Have you tried to clear SRAM? Did Mitsubishi guy explained you what number 8 means on diagnostic LED? Maintenance manual says you should go and check Function Manual for 640 Nexus but it looks like Mitsubishi keeps this manual very secured.

Can you contact whoever sold it to you and ask why on Earth they made a mess inside NC control? There must be a reason why they did it. That might help.

P.S this is very interesting, I have something on M640Pro control and it has kind of similar file, and here is how it is described:


The AT side modules and files required for this system are listed below:

location: C:¥m6y_ymw¥M736¥bin¥Release¥

file: M640EyePro.exe ( in your case T640eye, as in this example M-mill, Pro is whatever they call Pro)

main item: YMW creation module

description: Operation record application

it looks like the file belongs to this M6Y folder, which is a numerical control in itself. Dont think it is MAZATROL part of it, it has to be MITSUBISHI designed file.

I haven't tried clearing the SRAM, I don't know how to do this. The Mitsubishi Tech. did mention something about reinitializing or something similar. He did say without backing up everything properly, this could cause trouble down the road.
The LED on the board has mostly had a 9 digit with a blinking Red LED next to it. It's a bad picture but it's not an 8.

So the previous owner did not take very good care of this machine. It was rode very hard and put up wet...I don't believe it's ever had a PM done on it. The computer parts came loose while in transit, I'm sure of that.
I was wondering how the brand new hard drive could have the same symptom as the old one? It makes me question the hardware in the cabinet?

Try to clean SRAM , I will upload a procedure shortly.

And if you think parts came lose during transportation, than pull it apart completely and rebuild it, all data gonna be lost anyway after u do SRAM clearing.

I was wondering, if you have access to Windows and open Explorer. Can you? Can you start Mitsubishi Maintenance tool and create a back up? Although ... it is going to be SRAM backup and if SRAM memory is corrupted already, than what is the point?

The PC components definitely were loosened during the shipment. They sent me video of the machine in operation before I bought it. There is a missing screw on the processor board and the plastic shroud around the computer is loose. I think it's broken or missing screws. I won't be at the shop until tomorrow morning. I have gotten into the file explorer but not sure about navigating it. I will try to see if I can get into the Mitsubishi Maintenance tool.

The hard drives are infamous for failing. It was a bad idea by Mazak and Mitsubishi to put a spinning hard drive on a lathe, imo. I think the new replacements are solid state?

The drive MEAU sold you should have the relevant software already installed? It is possible this software version may not match your other hardware...?

You definitely need to re-initialize the control. That's standard procedure for any Mazak who's control is on the fritz. MEAU/Mazak will have the procedure.

All programs, tool data, etc. will be lost, but you should be able to reload the parameters from control eprom/or the hard drive.

Good luck with it!

The new hard drive from Mazak is a solid state drive. I expected this to fix the issues. It was an expensive waste in my opinion. The old hard drive displayed the exact same symptoms. I wonder why the support tech doesn't want me to try re-initializing the computer? He also acts like the Mitsibishi Tech is the only one that is qualified to trouble shoot this thing. I'm not opposed to paying a minimum of $700 to get it repaired if it actually fixes it.

I need to save everything I can from the original hard drive before initializing? I don't have any programs or tool library since I bought it and never used it.

Interesting that Mitsubishi had a hard drive with MAZATROL software. How about PLC logic file? That is supposed to be coming from MAZAK, cause they constantly update PLC file version. And you PLC file should be related to your machine electrical diagram. very interesting..

I don't know exactly what a PLC logic is? I honestly don't know a lot about these computers either. I have always had to order electronics from Mitsubishi though. I've been running Mazak Lathes since 2003 and they all have Mitsubishi components on them.

This sounds very familiar to when my qt-450's hard drive went out (machine was only 3 years old at the time). This was almost 10 years ago now so the memories are a bit fuzzy. I remember mazatrol wouldn't load up. We had a tech come out to install a new hard drive and they had us up and going the day he came out. Don't know if this is helpful.

Well.. machine has electrical diagram attached and may be some options or whatever, that needs to be reflected in PLC file. Like this JPEG file in attachment.
Does your Mitsubishi contact know what hardware you have and what MAIN A and MAIN B and LADDER files you need to be loaded on this replacement HDD?

So I bought a hard drive reader and was able to copy all the contents from my original hard drive to my laptop.
Should I reinstall the original hard drive and attempt to re-initialize? Or should I reinstall it and try to do the some sort of back up of parameters through windows before reinitializing?
Advice?
I'm going to call Mitsubishi back today and talk to them about the re-initialize thing as well. I feel like I didn't get the full story on how to properly install the new hard drive.
thanks

The Mitsubishi technician has my Mazak serial number and they asked me what numbers were on the hard drive before I purchased it. My assumption is, they work with Mazak to know what options need to be loaded on the drive. Maybe that's why they charge $1300 for $50 hard drive?

They charge $1300 for a $50 drive for the exact same reason a dog licks his balls.

Don't assume. Ask them if they loaded correct HDD image into your new hard drive. That is very interesting, that they have such a close cooperation with MAZAK and have access to HDD images. Doesn't look like MAZAKs style. And they charge you so much money because this is obsolete HDD, no one makes them anymore and there are only certain types available , that can be recognized by 640 Fusion motherboard ( BIOS system ) , so... basically, they have a monopoly to do what they want.

Update: I have the controller running. I was able to speak with Mitsubishi Tech support yesterday. I got a nice gentleman named Jacob. He was super helpful. I explained everything to him. He was able to do a search of their support history. He found a case with the exact same symptom with the missing T640Eye.exe file. I was able to reinstall my original hard drive and do the following.
Here's what the fix was:
1. Back up all the data and parameters using "mainte.exe" (Maintenance)
2. Install a new battery
3. Clear the SRAM (reinitialize)
4. Install Parameters
