FAQs / direct input commands in mach 3 mill

« on: July 04, 2011, 11:04:41 AM »

Hi all.
I need some help with a problem I am having with Mach 3 milling.
I am acutally running my astronamy telescope using nema 23 stepper motors and Mach 3 milling program.
When I am tracking a star / planet I use the X axis to control the rotation of the telescope mount.
I use the Y axis to control the up and down movement.
I use the Z axis to control the focus.
Now the problem I need to solve is this.
When the G code is running the X axis I need to be able to 'direct input ' commands to the Y and Z axis without stopping the program running.
Is this possible and if so how.
Thanks
