Thanks for the reply.
Im not going to make any money from milling. the reason i purchased the cnc machine was to cut out parts for remote control planes that i want to make.
Would make life a lot easier if i could run everything from my main PC, its going to be a pain switching between them, but i do understand that its best to give the CNC a dedicated pc.
Just going off topic..
This PC has no parallel port on it, its the only reason im not using it to control the CNC. I have seen a PCI & PCIe parallel port card on ebay, these are going for £11 & £19, i dont mind buying one, but will it work ok with Mach3
Thanks
Anthony.
