Thanks for replying anyway- that's definitely the number 1 cause of headache for this particular issue, from what I've been reading online. If anyone else is reading this with the same problem this should be your first port of call. Device manager > LPT Port 1 (or equivalent) > Resources > IO Range XXXX. It'll likely be 0378 or something like that, but not always. That then goes into Config > Ports & Pins > Port setup and axis selection. Make sure port 1 is enabled and the port address you found earlier is in there.
