General Mach Discussion / Re: motor tuning help

There is an example of the calculations here http://www.machsupport.com/forum/index.php/topic,12512.0.html

There is also an automated procedure 'Set Steps per Unit' on the Mach3 Settings (Alt-6) page.

There have been quite a few here who have had problems with Win7 and Mach3. Although it perhaps sounds stupid the best solution seems to be WinXP.

General Mach Discussion / Re: Problems with Z not cutting the right depth

« on: January 25, 2017, 09:57:30 AM »

The Z DRO shows the depth change but for some reason the stepper is not moving to the right depth.

Perhaps a mechanical problem with your machine (loose grub screw, slipping coupling, etc.) or an electrical problem (Z axis motor, motor driver, wiring connections, etc.).

Quite right, it's a  Campbell Designs board.

The only thing I have spotted so far is that your Outputs settings are incorrect. Disable all outputs except the Charge Pump (which is set to port 1, pin 17) then see if that makes any difference.

We need a bit more information.

I don't think you have the correct pin configuration for Motor Outputs but this relates to the make of controller.
What make and model controller (the bit that drives the stepper motors) are you using ?
A picture may help.
What make and model Breakout Board are you using ?

Is the stepper motor for the axis that has quit moving making a whining noise ?

General Mach Discussion / Re: Motherboards And Mach3, questions..

« on: January 23, 2017, 02:24:15 AM »

Mach3 seems to work best with the older PC's (~1GHz) so I don't think you would notice any difference between 2GHz and 3GHz.
What I have found to be more important is a PCI graphics card with 1GB or greater memory (Mach3 is heavy on graphics and when it comes to large files, turning off the toolpath display may be an advantage).
