I don't know if this is the correct group to be posting this question but if there is a more suitable one could someone let me know or point me in the right direction elsewhere. I have an 8 year old Colchester Tornado 300B with a Fanuc OT control. It has an RS 232 port on the front which I would like to use to download and store programs on a laptop. At the moment the operator is having to repeatedly input programs - not very efficient! Before buying some CAM software I have been told to check if the port is 'active' as some of these machines were fitted with ports but they were not actually activated for use. Is there a simple way to check? Also I am looking at CAM software at the moment; I need something which can take existing SolidWorks drawings and produce the code for this lathe. I have looked at a few different ones and I just wondered if anyone had any specific thoughts or opinions.
