 This is current plugin with just a change to the text file to indicate it allows 4 axis on control..

Yes, its a software driver which talks to ports, it actually knows nothing of printer ports and no port driver is needed either..

Hi Guys:
   I created a inch profile and ran some speed tests, all seems well BUT I did find a glaring error on my part,
when coming out of EStop I wasnt syncing M4's position, so a "Speed too fast" could occur after an enable
operation. This version repairs that.
   I ran several loops of G12I12 and G13I12's to check circles in high speed, I ran 40Khz at 350Inches/minute
and I cannot hear any trouble. Im running servo's which can hide small aberations, so I tested quickly on my
emco lathe as well which has steppers. All seems good so Im not sure whats up. Test this version if you have had
"speed too fast" errors, this will fix that up.

  You only need to update the plugin , not the driver or dll in this update...

Thx

Interesting.

   Ill run some tests. Your numbers are correct, in fact I wouldnt keep the kernal that low, Id run it at a minimum of 25000
or 35000hz, you dot have to tune the kernal to be just above your calcs, its best to have it much higher if you can. So Id leave it on at least 25Khz in your case.

  Ill run some tests and see what I see. I only use metric and havent had any trouble, but Ive heard from several that have
told me that inches dont work for them but metric does.. whichis curious as m4 and Darwin dont really use anything but steps.
The toolpath display is abotu the only thin that does.

  Ill run some speed tests and see what I see. Ill get back to you..

hmm, what kind of limitation are you seeing? I use 40khz and it seems good, are you having trouble when set that high..or higher??

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

Bob:

  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..

Bob:

   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..

Bob:
   
  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.
