I would say its either a virus or dodgy hardware such as keyboard or mouse.

Did some more testing tonight.

Did another fresh format of C drive and a fresh install of Windows XP from an original CD.

Removed a relay board and use the remaining relay of the C6 spindle board and re-wire.

Same thing happen, one more test I did is check CPU usage under Mach3.

Only to drive spindle, about 20%

X axis + Spindle = 70%

X + Y + Spindle = 90% and more, not suppose to be like this.

I don't know what CPU usage should be but much too high to get a stable system.

And again, calculator, internet explorer wizard and some others process will open without warning.

And now, I really don't know what I should try.

My hard disk has 3 partitions, C: D: and E: I only formatted the partition C.


One desperate guy.

COU useage is way to high but you realise that already. On my Pico mobos  the CPU (1Gig ) rarely gets above 10%, having said that I use the SS so that takes some overhead away from the computer.
Have a look at the processes and see what is using the memory.
If its an Intel CPU look in the BIOS and disable any of Intels power saving features.

It is an old 1.4Ghz, I f I remember well, K7SOM v5.2C

I have downloaded all the latest driver, including on board video

This board was working great before I remove it.

Could it be possible that, if partition D: and E: have not been formatted, something like a virus or malware keep Fu... my C drive.

When jogging with the spindle running, it slow down a bit, probably due to CPU being too busy.

They're maybe a dozen of process running, only one I could not recognize, will verify that tomorrow, I have stopped it to see and it makes no difference.

Thanks to keep posting, really appreciated.

try switching to a different keyboard. maybe a key is stuck or a chip is lodged under a key. are you using a pokeys or keyboard emulator? i had a problem with pokeys doing strange things.

I could try it, did not think about it.

No Pokeys

After many, many, many hours, I been able to get what I could call a more steady system.

I could keep the CPU usage between 10 and 13 %

But when moving the mouse, they're still spindle speed variation between 100 and 150 RPM

CPU usage rise to 35% when moving mouse but only when Mach3 is running.

No variation of CPU load on the desktop

Mach3 clock is rock steady at 25000.

Have replaced motherboard and put another HHD, format (with no partition) then New Mach3 download and installation.

Still have problem with windows program loading without warning.

Tried another keyboard and another mouse (serial) with no change.

When spindle is running, the start menu is blinking very fast, sometime stays on desktop, loose mouse and keyboard.

I think, I will re-design every thing from the beginning.

Re-wire everything because I don't know what to do and since no body have ever experienced this, (I think) will try to resolve by myself.

This system was working great before, absolutely no flaw and then...

Jeff,

All the probs. you have described could be attributed to severe electrical noise.

Have you perhaps left off an earth connection that was previously there ?
Have you added another connection which could be causing a loop ?

If it was working OK and now it isn't working then you must have done something additional to just changing the motherboard.

Have you checked the bonding of your computer earth and machine earth to your incoming supply earth ?
Have you checked the polarity of your Live / Neutral (or whatever you call the AC supply) is correct ?

(it is not unknown for power company's to rip out earth stakes or earth wires to become disconnected).

Still have trouble with CPU usage.

Took some instant picture of running process when Mach3 is running and when it is not.

1st picture = with
2nd picture = without

When running a program, CPU is at the top 100%

Done another fresh install with another computer (desktop with case) outside the control box.

Interrupt process is taking more than 50 to 60% of CPU usage.
