Sherline Mode kills Output#1 - why??

[frogblender]

I'm having missed steps problems, and want to try Sherline mode.

When I enable Sherline, Output#1 (which is my coolant) ceases to function - the physical pin is always stuck low (.063v).  Mach's Diagnostic page shows Output1 toggling properly, even though the physical pin is not.

When I disable Sherline, the physical pin toggles fine.

Output#1 is the only output I use (other than Motor pins, which seem fine); I didn't try the other outputs.

Any ideas ?

Have you tried the lockdown instead of the development version?

No.  My original goal was fixing my suspected missed steps, and the siren call of the "updated parallel port driver" in the development version was too tempting to ignore.  Is it worth going back?

I've bit bullet and ordered a smoothstepper.

Probably best to at least try
