What is SS/ESS?, what do they stand for?

SS means SmoothStepper and is usually said when referring to the original USB SmoothStepper.
ESS means Ethernet SmoothStepper.

Regarding the quadrature spindle output, it made no difference on my machines so I just dont use the spindle override on the two machines I still have the SS and ESS on. I have a further two machines that have CSMIO/IP-S and IP-A controllers on and I can use the spindle override pot on these machines with no problems.

I wired the cw & ccw of MRJ2S-350A's CN1A to SS today, it is now in step/dir mode. Will set the Pr tomorrow.

Ok, there was a slight problem with my homemade board;


when MRJ2S CN1 connected to this board it does not correspond, but it does on another system, so I'm sure something is not right with the board, will re-build a new board with my Direct PCB printing epson T22:

Here is the MRJ2S-350A in step/Dir mode:

This is the new board I made:



and still can not get the AC servo turning, on another Mach3 controller the BOB is a C10 board form CNC4PC and it worked perfectly with SSD (blue squary shape in the middle of the board).

What are the blue things?
Is everything else working?

Sorry, is SSR (Solid State Relays) I thought with the new board I would be able to run the AC servo but not.
The board is not the problem, stepper driver wired to this board works, but not the signal out from CN1A(MRJ2S).
Also I get an error from SS when AC servo is powered on and then SS crashed.
Is SS's output signal the same as C10?

Are you trying to send the step/dir signals via the relays?

When you say it worked via the C10 are you meaning you had it connected via the parallel port or via the SS to c10?

Is the CN1A not the inputs for Step/Dir or are you talking about some other output from that connector?

Have you set the SS config up for Step/Dir spindle?

I checked some of my previous controller wiring, this one:



The SS had a C25 Terminal Board, MRJ2S's Amps worked.

Are you trying to send the step/dir signals via the relays?
Yes, the C10 board is wired this way and worked pretty well for MRJ2S so I used the same method for SS, but didn't work.

When you say it worked via the C10 are you meaning you had it connected via the parallel port or via the SS to c10?

PC connected to C10 via pararell cable, then from C10 pins 2&3 to MRJ2S CN1A's CW & CCw result = link above.



Is the CN1A not the inputs for Step/Dir or are you talking about some other output from that connector?
Yes this is the input for Step/Dir coming from SS.

Have you set the SS config up for Step/Dir spindle?
I haven't done any changes in config. I disconnected one of the stepper driver's step/dir wires off SS terminals and wired CN1A's cw wire & ccw wire to the terminals and test if it spins, but it doesn't.

I certainly wouldnt think it a good idea to send step/Dir signals via any sort of relay, wouldnt even be using any opto isolation if possible as the drives side of things will almost certainly be isolated.
