Sadly, the so called Enable circuit on most stepper drivers is actually a disable input used to remove torque from a powered motor so that it can be turned by hand. Leaving ENA+ and ENA- not connected is common as they are not usually needed.

Please do not shoot the messenger

But have you set up the motors in Mach4 control config not the ESS,
Motor page
Motor check box clicked ?
Motor name clicked and turned blue ?
Required fields fill in ?
Apply
Ok

Exit Mach and restart

Yep both step and dir LED's light correctly.

Hi,
this is from the MSD542 manual:

Quote
ENA+
ENAEnable signal: This signal is used for enabling/disabling the drive. High level (NPN control signal,
PNP and Differential control signals are on the contrary, namely Low level for enabling.) for
enabling the drive and low level for disabling the drive. Usually left UNCONNECTED (ENABLED).

So as Steve suggests you can disconnect both terminal and the drive is enabled. Try it and see.

Yep, done that. That's how my machine has been configured and operating for a number of years (Mach3 no ESS)

 I've been an idiot. I had one of my jumpers incorrectly set. How I missed it I'll never know.
Thanks for your help it has been very much appreciated.
ESS + C11 now have movement.

Craig, you've been very patient, but for now I will carry on with the new configuration.

I have purchased a C10+ Laser from Endurance Lasers so now to get it working.

I hope you'll forgive the bother I have given you and maybe I can still raise questions..
