Not sure what that means.

I have seen two things that make me suspicious that Darwin and M4 may have some issues playing nice together.

One issue is that on startup, the charge pump led doesn't illuminate.  I have to cycle the disable/enable  button to turn it on.  I see the leds come on briefly at startup,  but then go off as the lua screens load.

Second issue is that none of the indicators in the M4 diagnostic screen change state.

Hello ,i have been reading the posts for about a hour or so and i have tried what i have read but i can not get this thing going .

 So here we go, converting from mach three running several years now, i can go in and out of e stop hit my switch and it e stops, no motor movement ,set charge pump pin 9 to 12.5 HZ enabled it toggled it on,  turned yellow shows 12 htz.

Motors set and enabled plugin ,mapped mach 4 and enabled ,steps set initial vel and acc set to square wave, and nada nothing will move  .

So then i have a extra smooth stepper different pc go thru set up same deal ,i can not get this board to enable with Mach 4 (mach 3 printer port every thing works perfect)
 
 
first pc running xp32 bit and parallel port with external graphics card , second pc windows seven 64 bit mach 4 either net smooth stepper with plugin.

I can not run another B/O board dedicated servo board.

  Do the DRO's count when you try to move?

I can tell that it is not getting the signal for the charge pump .because it has a relay on it and you can hear it make when the pump goes active.

I have done some further investigation of the mach 4 and this is what i am getting , i come out of e stop i have two enable signal's active even though they are not set up , i tried everything to get them to go off.
  However if i try to enable a particular enable pin ,it will not enable.

I have limits working if i hit a switch it shows in mach in diag. page,  however no outputs will work at all or enable pins, that is were i am at so far , and i am stuck and can go no further.

Well, if the DRO's count, then M4 "thinks" all is fine, as does Darwin. That leaves only the  charge pump stopping motion really, did you try jumpering it off on the board to see if this enables motion?

Art here is a link to it   http://www.dmm-tech.com/DMB4250-8B_main.html   there is also  mach config screen shots that shows its config , and mine is set up exactly the same .

As i see it there is no exposure to the charge pump pins.
