Look at the download site.
There is a file to optimise your pc/notebook for mach3.
I had problems with my notebook in combination with mach 3.
Search the forum for "motors chatter".
There is some information about my problems with notebook and mach3.
The major thing I changed is to set the computer to Standard PC NOT ACPI PC.
The problem with notebooks is that the voltageof the processor is controlled for optimized battery life.

Brian,

I looked at the windows setting file and changed some settings in windows at my notebook.
The result is excellent!
The motors run very smooth now.
I've also changed the motor settings, now 2000mm/min and 300mm/sec2 with no problems
Old settings 500mm/min and 40 mm/sec2
No matter what screen I'm using.

Thank for the help right now.
Next thing is to make my electronic cabinet all wired up and then mill my first part.

Brian,

Where I'm still confused about is the difference in motor behavior between the screens?
How can that take effect on generation off pulses or the performance off the computer?

At this moment I don't have an other computer available.
I will see to get a desktop computer to test.
Maybe I borrow the computer from my wife.
Don't tell her!!

Brian,

I ran the driver test and hereby a screenshot.
This looks clean to me.
I attached a small video (zip file) with switching from screen Program run to Toolpath.
You can hear the difference clearly.

I was also thinkingh off a limitation off the free downloadable version I use.

Thank for the reaction.

I did everything mentioned above, with no results.
I noticed that in the Toolpath screen the processor of the computer uses 70-100 % of the capacity.(task manager)
In the screen Program run only 15-17 % of the capacity.
Isn't that strange?
Any explanation?

Chad,
Thanks for the reaction.

Mill:
homemade conversion of a Cincinnati Millacron PF25
tree 6.4 Nm 1.8 full stepper motors
tree bipolar drivers up to 25600 microsteps/rev.(jumper selection) 20 Vdc- 50 Vdc
Computer:
Dell Latitude D800 notebook
1.5 Ghz
1 GB Ram
Breakout bord:
CNCdirect breakout board for Mach3

When I run a test g-code program I only use Mach3.
I even tried to turn of all the start up programs at windows start up.
Turned off all the energy power saving programs and screen protection.

I ran drivertest.exe and this looks better with all those programs turned of, but the result is exactly the same with or without turning the programs on or of.

What I don't get is what is the difference between the screens in Mach3, what could cause the difference in behaviour of the motors?

My name is Geo Hagen and I am a newbie.
I am just setting up mach3 with the drivers and motors

I have a problem with some mach3 screens and the behavior of the motors.
In the program run, offset, settings and diagnostics screen my motors don't run smooth.
In the other screens, MDI and Toolpath, everything runs smooth.
Any suggestions?
