Pulsing too fast
« on: February 05, 2013, 10:12:23 PM »
I got the new computer built, loaded the latest Mach3, put in my saved XML, created the proper Icon, loaded in my plugins for pokeys and machmotion. I basically tried to put everything back like it was in the old computer.

When I run the drivers test I get "Pulsing too fast". Kernel speed is 25k.

The computer was built to be dedicated to the mill. I have not actually hooked the computer to my machine yet.

Intel i3 3225
Gigabyte GA-B75M-D3H MATX Motherboard
Sandisk Extreme 120 Gig SSD drive
Kingston HyperX Red 4GB DDR3-1600 (PC3-12800) CL 9 Memory Module
LG 24x Super Multi Internal SATA DVDRW DL Drive
Parallel port PCI card (has one port on board and one that ribbon cables off) - The same card from old computer
PCI wireless network card - The same card from old computer
Windows 7 32-Bit

I did try turning off all services and startups in the msconfig, then rebooted, and that did not change anything.

I am looking for ideas to try next. Sometimes during the test it will say system stable for a bit, then go back to pulsing too fast.

The PCI wireless network card may cause you trouble in the long run.

Set your Kernal speed to no more than you need based on your axis tuning.

Look for a clean test as far as noise and other operations causing blips.

Just a thought, (;-) TP

Can it be causing me problems now? It did not cause problems in the old computer. It's kind of hard to not have network access and get a computer up and running these days....

IS the OLD pc the one you always had problems with ? (;-) So how did you know the card did not cause problems ??

ANYTHING that can interupt mach3 such as a network card COULD cause a problem at times.  SOme PCs don't have a problem Some do, Why push your luck?  This is a dedicated CNC PC for a machine correct?

The problem with the old computer ended up being a bad memory stick (confirmed and narrowed down to which stick with memtest). I could not even reload windows xp until the memory stick was removed, I kept getting page faults, BSOD's etc. Once I removed the mem stick then it loaded up fine again and that computer is working good and for sale. It worked fine with Mach 3 prior to that crash.

It did not have any issues with the driver tests or anything either. I could not say for sure that the card would not cause something wierd long term as I never cut any big projects, only cut air on a couple simple routines.

Anyway, back to the new computer. I went ahead and disabled that card in the device manager and rebooted. Getting the same issue.

Is it possible the computer I built is too fast and Mach3 does not like it?

Tried a bunch more stuff and no luck so far. I am going to browse that vista forum. It seems some of that may apply to Win7 also.

I do notice something. When I run the drivertest, the pulses count just climbs up for a second or two then goes back to 0 and displays pulsing too fast. It is like it starts to run and then just stops.

I messed with this for about 5 hours again tonight with it connected to the machine. It just won't communicate. It is like the pulse stream or communication works for a second then dies. It appears to do the same thing if you just run Mach3 also. I tried all kind of different things in the bios, disabling all unnecessary devices in the hardware settings. I tried setting the printer ports to support legacy PnP, and all the different options for use of interrupts. I tried using msconfig and shutting everything off and rebooted. So far nothing stops this from happening that I can figure out.


I tried the special driver in Mach3 and that did nothing, so I set it back. I tried reloading the mach3 driver. No luck. This is a huge dump of valuable time :(

I pulled the wireless network card and got the same results. I spent a bunch more time tonight trying various things and finally gave up. I don't think there was anything else to try. Mach support helped me and they had no further ideas either. They said it was the worst drivertest they ever saw LOL. 

I replaced the 32 bit Win7 with 64 Bit Win7 and have everything re-loaded and ready for a smoothstepper. I am just waiting for a paypal invoice for a smoothstepper. Hope this works....

I didn't think Mach was even supposed to run on Win7?

Yes. It is supposed to work on 32 bit Win 7 with parallel ports. It will work on 64 bit, but not with parallel ports (have to use external motion controller).
