In all the videos I've watched, they all use a Parallel cable between the MACH3 PC and the CNC Control Box.

My CNC3040 was sold as a USB CNC but the control box still has a parallel port on the back. I purchased a parallel cable but I could not get Mach3 to work. I went through the setup like all the videos were showing and in the MACH3 settings where you configure your PINS for the Parallel Cable, I only ever got one or two green indicators working and nothing I did would make it work. I couldn't control anything on the CNC using MACH3 so I went back to using the USB CNC software that came with my CNC Machine via USB.

So do you think it would be possible for my machine to run MACH3 via USB? My Control Box for my CNC is labelled as T-D Axis Controller. It is black in color with an angled front panel which has two power switches (Main Power and Spindle) with a rotary pot to control spindle speed and finally a big red emergency stop button - if that description helps.

Inside the control box are the following boards:- JP-382C, JP-1482 and JP-1635


Thanks!

Don't take this the wrong way but don't butt in, start your own Thread.
It's confusing trying to address your problems and answers in someone else's thread when identically named hardware sourced from China can be very different electronically.
Additionally you didn't say what spec your PC was and Windows 10 doesn't do parallel port, neither do any other 64 bit versions of Windows.
