Woffler:

   I dont think there is. However, you basically select from the menu config of Darwin the method of spindle control
you wish to use.

Hi Wofler,

  Cant think of why if its turned on in m4 config, Id check with them to see what turns on the jog button, as long as its mapped it should
at least enable the button. Doesnt sound like an Darwin issue..

Make sure that the axis settings have the proper "home pin" selected in Darwins setup mask, as well as polarity
of the switch. Mach4 is only set to recognize the home switch input for display so enable the home inputs in Mach4, but also make sure on the
motor selections in Darwin that the proper input is selected for each axis..

  If you press them manually and have it setup, the LED's in Mach4 should light up when their pressed. Leave all home/Limit switch inputs
in Mach4 as "High Active", only use Darwin Inputs mask to set the actually polarity of the switch.

Hi George:

  As I recall, the license only enables outputs, the step/dir should work fine even with no license.
If the DROs are moving, and the axis arent, make sure Darwins step/dir outputs are setup properly,
they should run even with the trial. Dos the pulse engine test show proper pulsing? You should be
able to jog from there as long as your Estop is reset..

Archive Purpose:

    In offlist emails it seems Jame's machine is returning to start but the job has strange scallops and profiles in it.
Best to mention here for archival use, if any machine can run a job and return to its start, then there is no issue with pulsing.
Pulseing either works, or doesnt in terms of being good enough to work. A machien that returns to home has lost no pulses,
it has received all of them so they cancel out to get it home.

   The problem on this system is yet to be determined, but I suspect slow acceleration on axis. Plasma machines are the most
affected by this as they tend to have slow accelerations, which can cause CV systems to have bad artifacting. Best rule is use as fast an
acceleration as you can, and keep axis as close to each other in accel as possible. If one is slow to accel and the other is fast to accel
artifacting is maximized.

Thx, Just a note.

Its odd that happens, it should display a number if its pulsing, though the waveform seems to indicate at least partially stable operation..
Does it sound odd when jogging one axis? Smooth or rough?

The photo does seem to show a noisy waveform, but it has no puilse number showing, which is very odd.
Does it ever show a number?

Hi James:

  It doesnt sound bad, the pink in the line means the vast majority of interrupts are coinciding with expected intervals.
If you can post a snapshot Ill tell you what I think, but it sounds correct, just different from mine in the video. If the blue
lines are very prominent, then you could have something intefering.. hard to say, but generally I found Darwin to be less
susceptable to noise than Mach3's driver.

Steve:

  Sometimes yes, sometimes no. I havent heard of anyone having trouble with Darwin due to internal graphics, Id run it and see.. It should work OK,
you just have to be in XP or 32 bit win7 for it to work.. Memory doesnt affect Darwin, but it may affect M4..
