im having a problem with the port im using that is suppose to connect the Break out board to the computer. ive used 2 older computers to connect to the BOB using mach3 and it did fine. the 2 older computers had the 25 pin port on board the mother board. Now i want to use a newer computer to run my cnc machine but it didnt have the 25 pin connector so i bought a "parrallel port" to put into my new computer to connect to the BOB but it still doesnt work. I noticed that in mach3 the port is labeled "com" and in my hardware settings the port that i installed is a "lpt" is their a way to change this or is "com" and "lpt" port 2 different types.
