Hi Guys:

 Apparently the api has changed so Darwin will have to be recompiled when I get a new sdk. So stay with the older version of 1900
if you wish to test Darwin, Ill post when I have a 1914 level ready.. :(

Art,

Just to be clear.  This version will only run with Mach 4 build 1914 and later?

  It was compiled under the 1917 version sdk. It should, hopefully, run on all future versions but of course will be updated
as things go along..

  Sounds like the driver didn't install. Are you running a 32 bit OS of XP or Vista.. Win7 may work as well
but it must be 32 bit.

   If your in Vista or Win7-32 bit , you may find it helps to run DriverTest.exe by right clicking and selecting "Run as Administrator".
DriverTest.exe will then try to reload the driver if it doesnt find it..

  If your in XP , you can run "Add Hardware" form your control panel. Tell it you want to select the driver and select the
folder with the driver in it , it should find the Darwin.inf file and load the driver..

Art,

I did a clean install of Mach 4 Build 1914 and Darwin2014-1-10.zip.  I now notice a new behavior that wasn't happening with the previous versions that ran with Mach 4 build 1900 and prior.  Using the same motor tuning settings, I'm now seeing an occasional "pop" in all three configured axis when I jog.  I tried re-tuning the motors, but the problem got worse if I went above or below the original calculation.  It's better at lower jogging speeds, but nearing 100% jog rate I start to see e-stops with messages saying that Darwin is too fast.

Any ideas?

Freeman:

   The pop's are the frequency going over the kernal speed.
Those messages are only generated by Darwin if the steps/sec times
the max velocity is greater than the kernal frequency.
  It means you need to lower the speed, or raise the kernal speed.
In the end, the maxvel in units/min must follow the formula

  maxVel / 60 * StepsPerUnit <= KernalFrequency
