Hi,
I am wanting to set up another computer to run mach3 for my CNC router (stepper driven).
The computer that was running my machine is giving me trouble on boot up.
I have aquired another computer to run the machine.
Now the problems I have with this machine are that I cannot get the steppers to run "sweetly" like they were with the old computer.

I have copied the XMl file to the new machine and have manually checked the settings multiple times to make sure they are the same as the original.

I have also tried multiple settings other than the original for the motors, but am unable to get the steppers to sound as I feel they should.

The original computer specs:
AMD Athalon   1.1 GHz    1.5GB RAM

Pulse Frequency  25376  Steady

Driver Test...System Excellent
Pulses per sec  24406 - 24605

New Computer:
Pentium 4   3.06GHz   2.99GB RAM
Pulse Frequency  24789 - 24811

Driver Test....System Excellent
Pulses per sec   24941 - 25022

OS Windows XP

Cheers....Kym
              

is the new machine an ibm or novatech ?

Are the motors making a growling sound ?

The new machine is a desk top HP Compaq.

Yes the the motors are making a growling noise...like they are labouring.

some computers do this, I've not figured out why yet but i'm looking into it. I find dell, viglen, fujitsu, do the job without this problem, and i'm sure there are many others that work well.
