Loading programs from USB drive on Fanuc

[buildyourow]

Almost new Fanuc i-series control on a Doosan.

I cant seem to get programs to load from a USB thumb drive. Parameter 0020 is set to 17. Drive is 2gb formatted FAT. I successfully got a program from the control to the drive but when I try to go the other way I get "program not found". The control sees the drive and the files.
Does the program need to be a .txt file? Been doing this with rs232 for so long I defaulted to .nc

This is the kind of shit that makes me never want to buy a fanuc controlled machine. Hope you get it figured out. Thoughts and prayers.

Copy .nc files from USB and paste to CNC memory works fine on my new DEM 4000 with Fanuc Oi-Mf plus control. What does not work is doing the same from a compact flash (CF) card. The Ellison Applications Engineer visiting today could not figure it out either. We tried both CF channels in the control.

Few things to try. Make sure the filename has no weird characters. Not sure what the actual limitations are, I only use numbers. I also don't have any .NC or anything like that. Just the program number without anything else (on windows computer you have to show the extension under explorer options to be able to rename the file like this)

If the program starts with O0000 I cannot load it, needs to be something else than four zeros (not sure why)

I experimented on this some 15 years back, so I may not remember exactly, but this is what I found:
Program number 0 is not a legal program number. You cannot create/save/execute this program number.
However, it can be used as a temporary program number. For example, if you are copying a program or a part of a program, to create a new program, and do not enter the number of the new program, then it would be saved in program number 0. You can insert this program into some other program, but other than that, it has no use. It would be wiped out after a power cycle.

The manual explicitly states that

Yeah, I can't have any file extensions loading from USB. O0001 F-INPUT then execute. Should load as current program.

As usual, the solution was simple.
The new control wants a % at the start of the program. My 18i doesn't seem to care.

When going FROM the USB TO the CNC, you must use the "Change Device" key to get the machine to look at the USB rather than internal memory.
So:

Go to "edit" mode

Press "Folder"

Look near the bottom and you'll see "Device Change"

Press it

Then select "USB" from the choices.

You will now notice that the directory has changed from the CNC internal memory to the USB drive.

Highlight the file you want to read into the memory.

Press "FGet"

Press "FSet"

Press "EXEC"

The file will now be read into the CNC memory.

MAKE SURE you press "DEVICE CHANGE" again and select "CNC" from the choices to go back to the machine's internal memory.

Many machines cannot read a USB over 1.4 MB, try reformatting your USB to that, you can find the software online that allows you to convert any size USB to 1.4.
