Title: No pulse line box
Post by: fredjr45 on December 28, 2009, 04:39:43 PM

When running driver test it says excellent, but there in no line in the box.  the pulse per second is 12305.  Sorry if this has been asked before but I could't find it.  Thanks Jimmy.

Try the special driver and see if that helps. It is in the Mach3 folder and double clicking it will install it, if you need to go back to the normal you will also see that in the Mach3 folder and again double clicking will install it.

Thanks for the quick reply.  I took another look and there is a line,  it is off the scale.  I can see some spike coming down from the top.  How can I get the line in the box.  Thanks, Jimmy

What do you have your kernel set to? I have never seen the line being outwith the box so dont really know what to advise.
Have you tried to see if your motors are working correctly the way it is?

With kernel at 25, pulses are roughly around 40 us so if your speed is 12,305 it would put you up around 80...at the top of the window wouldn't it ?

Your pc might be too slow.

I have the kernal set to 25.  The motors do not run.  This is a new build and are just starting to try and get the motors to run.  Thanks, Jimmy

I'm not good with computers but I think it is 1600MHz.  I know it is old.

That should be plenty for Mach, min requirements is 1,000MHz. Memory is also important.

There are 74.5GB of memory.  Thanks, Jimmy

Thats you hard drive size, it is RAM that is important, min if using XP should really be 256 Meg but 512 or more would be better.

261,424 MB RAM, windows 2000.  I think that is right.  Thanks, Jimmy

Think thats probably Kb, if so then that should be plenty for Mach on windows 2000.

Have you tried the computer with some motors to see how they perform?

The motors do not run.  I am just starting to get the Mach running.  I did the special driver and now have no pulse.  Thanks, Jimmy

I thought maybe the special driver would work when you said you had no line so best just go back to the original.

Might be worth doing the optimisation steps detailed on the downloads page (near the bottom)

I changed computers and now have a good pulse rate and line with very little spikes, but the motors still do not run.  I have used the Gecko troubleshooting diagram and have come down to the "check controller timing G203V step input specs: min step '0' time = 0.5 uS min step '1' time =3 uS".  Could someone explan this and how do you correct ifd it is not right.  Thanks, Jimmy
