Arturo,

I am using a C11G and a C15 relay board. The two relays switch another pair of mult-contact relays to reverse the windings on the DC controller and enable/disable the DC controller and isolate the other relay so that it cannot get forward and reverse together.
It works fine in LPT mode, just not with the SS.

Simon,

Sorry, I do not get it, it should work exactly the same way.  Is the C11G receiving the signals? What is the status of the LEDs?

Arturo,

Please see my e-mails to both you and Greg regarding this.

I do not get it either. It should work the same. It just doesn't!

The C11G works fine when connected directly to the LPT port but when connected via the SS all sorts of strange things happen.

The latest SS plugin has improved the situation but not fixed it.

Simon

Simon,

Please send me a copy of your xml file, I will test it on my SS.

Arturo,

I have tested the XML that you sent and it made no difference.

e.g.
M3 S500  - starts ok in the right direction.
S1000      - increases the speed.
S2000      - increases the speed.
S1000      - speed decreases.
S500        - speed decreases.
M5           - spindle stops.
M4 S500  - spindle runs in the correct direction but extremely slowly.
S1000     - no change
S2000    - no change
M5        - spindle stops.

This does not work on my system. Changing the direction stops the
spindle control from working until after a EStop is called.

It also works the other way around using M4 first and then M3 later on.

Thanks
Simon

You're not alone.  I have SmoothStepper v17d and C3 pulse indexer trying to do threading on a Sherline lathe. The numbers in the rpm box on Mach3 flash all the time the motor control box is on, and occasional when it is off.  The C3 card seems to be ok. It looks like a software filtering of electronic noise issue.
