Mach 3 won't run under certain Laptop
« on: May 11, 2009, 10:41:58 PM »
I installed Mach 3 on my IBM X31 land an older HP aptop and it works perfectly but when I install it on my dell and T41 laptop it doesn't work.  I cannot use hot key to move the axis.  I also try to use the built-in wizard feature to generate some gcode and run it.  Still it won't run...(the X Y Z axis numbers were not changing)  Yes I have cleared the reset and I just don't know what's wrong with it

Some laptops will not run Mach but sounds like you may not have the Jog control switched on.

Laptops are notorious for not running Mach properly. All the power saving features in a laptop prevent the precise timing that mach needs to operate properly. There is a document on the forum somewhere about optimizing a laptop for use with Mach. That may help but in my experience it still does not work as good as a desktop machine. If you set on using a laptop then I think your best bet is to use a SmoothStepper: http://soigeneris.com/Warp9.aspx . The SmoothStepper handles generating the precise timing pulses needed by the stepper motors (better than the LPT can) and lets Mach worry about trajectory planning and the UI.
