Hi,
I would suggest posting on the Warp9TD forum about ESS setups ona new installation.
I had a bit of a battle eight years ago when I set up my ESS with Mach4.....but after eight years I've forgotten all the steps I took.
The basic problem was that I had not taken the correct procedure that allowed Mach4Hobby to operate through the Firewall and AntiVirus software,
although that was not plain to me at the time.
