Windows 7: File Corruption During Network Transfer

We are having the same problem. Windows 7 Pro 64bit machine hooked to a Haas milling machine through a router. The network connection to the Haas is slow and files sent to the machine grow in size after being sent. Sections of previous G code files get chopped up and inserted into the sent file. I'm wondering if its a Windows 7 thing, because I still have my old 32bit XP machine hooked up to the same network and it sends to the Haas just fine with no data growth.

Local Haas guys are baffled. Had them over twice to look into it and upgrade the floppy driver. Made no difference.

Have you tried the steps I've suggested to the other person?

I did try your suggestions and no difference. I did what noahwass suggested and plugged the 150' cat5 cable from the Haas machine right into the Win7 machine. Same thing. Slow to connect, and files grow on transfer to the Haas. So this eliminates the router and switch as problems. So we're down to ethernet adapter in Haas, or some Win7 issue since the XP machine works. Any further ideas?

USB thumb drive transfer works fine.

I'll think on it, and hope someone else jumps in, but for now I'm a little stumped, I'm afraid.

Well I made it work by NOT dropping the cutting programs into the Haas but by creating a shared folder, and having the Haas "pull" the files down. Works well so far. Drag and drop to the machine would be slightly easier, but oh well maybe it will work itself out as more shops switch to Windows 7.

Interesting. I wonder what the difference is. Sorry I didn't have an answer for you, but at least you've given me the knowledge to help those who come by with similar troubles.

I just wanted to update this thread and mention that I was able to move a small 4KB NC program to the machine uncorrupted. A larger 1,478KB file still corrupts when it gets transferred. It's unlikely and unreasonable to suggest or assume that anyone can create smaller NC programs and move them to their machines, but if you have short, simple toolpaths, you can most likely transfer them with no hassles.

WebMattR, would it be safe to assume that network hardware can be ruled out if this smaller program is making it through with no problems?

Solved my problem (so far)

Hi Guys

Solved my problem as of middle of last week so far.

Instead of mapping the drive of the Haas mill I just address it by its IP address. We had a conflicting IP address which we sorted out, and I had the driver on the Haas upgraded from 12 to 13.009 which is the latest driver for that model and year of control.

I am now dragging and dropping from my desktop into the drive of the Haas machine, and have had no corruption of files.

Its only been a week but anything from a few kb to 1.8 meg has worked.

Our IT guys finally got around to looking into our file transfer problem and verified that it is a problem between Windows 7 and Haas' operating system/firmware/driver. We were able to transfer files using WinMend File Copy and the IT guy was able to transfer files using basic DOS commands at the DOS level. Anything else gave us corrupted files.

From here, I'm going to call Haas and make sure that they're aware of this and see if upgrading the machine OS to the most recent OS/firmware/driver will do help as it may have in Generalchaos' case.
