I just got two more used Kitamuras with Fanuc 16i-M (the i-MA, not i-MB), and am having trouble sending files to the Fanuc Data Server board.

I am using the Fanuc Program Transfer Tool to transfer gcode files to the machines. The machines are configured on the network, and I can successfully connect to them from using the Program Transfer Tool on my PC.

However, I am unable to send files from my PC (using the program transfer tool) to the machines. Interestingly, I am able to create folders on the machines (using the program transfer tool), but still I cannot transfer files.

The Program Transfer Tool gives the error "Fail to download file." The error is instantaneous - its not like it tries for a few seconds and then fails.

I have two other machines that have slightly newer Fanuc 16i-MB controls, and these work fine. I have the same configuration for them all on the machine's ETHPRM screen (except for unique IP addresses), and also have the same settings in the configuration for the Fanuc Program Transfer Tool.

Is it possible that the machines don't have the necessary options from Fanuc even though it has the physical hardware?

Any ideas why this won't work?
