Hi Sage:

 I got that error too, but then I was too lazy to redownload my license.. I fgured it changed again. Let me know if the license issue shows up after
a redownload. Ive found I need a new license from time to time..

Hi All:

  A bug was found tonight an fixed which caused the overbuffer error on jog. Here is a new plugin, an official one will be released soon.
You only need the mcDarwin.m4pw and mcDarwin.sig files replaced to fix the trouble..

>>My understanding was that with Mach3, the THC up/down moves  were done by the LPT driver.

  They were. However, the spec of Mach4 was that such things were not to be done by the device. Darwin was completed long before Mach4
and to that original spec. There is no backlash or thc in Darwin. Darwin is at this point meant to be a bridge, it allows you to use Mach4 as
a printer port user, but its capabilities will never be increased, it is a basic 4 axis printer port driver that will do most things, but it wont
do THC, Backlash or threading.

 Youd need to put in the CVruntimes for VS2013..

Hi  Greolt:

    Darwin knows nothing of THC. It will pass signals from pins back to M4, but it has no idea what M4 will do with them.
You may want to ask the guys at M4 what thc functions are built into Mach4, but natively Darwin has none.

Im afraid I cant think of any reason off hand why the motion would be hesitant. The driver stats are great, so the timer seems to be running fine. It could be video card or something slowing
the system or some other effect, but I havent experienced anything like that in m4, its always been smoother than mach3 for me.

Sorry, yes, thats the setting, set it to 5 or 10 to see if it helps.

Hi:

  Well, I have to say thats an Excellent! waveform. You should have no smoothness issues. Have you set for at least 5us pulse width additional in the diags menu?
Did you try with lower acceleration just as a test? Is it smooth in the Jog window in Darwin? Id say wothing strange is going on. Is it smooth in jogging? How bout a
g1 move? Any difference?

Jason:

 In Mach4 there is a menu item ( under diags I think) for Darwin, In there you will find a few settings like encoders and Pulse width..

Hi Phil:

   Pulse widths the only issue I have seen with Darwin that makes it rougher than Mach3, most report the opposite. I
didnt have to increase my own, but Im using servo's. Every report Ive had of rough motion till now was fixed by increasing the puilse width
in the Darwin Setup options in Mach4. Step width is usually the culprit, does it seems to have any effect for you?
