General Mach Discussion / Spindle/Router Control from Mach 3 Config Screen

« on: May 26, 2014, 09:06:16 PM »

I have a wood router as the spindle. I would like to be able to turn on/off the router from the Mach 3 Config screen or keyboard when Gcode is not running.
I only have an outboard AC power switch now.
I think I can get the breakout board and Mach 3 output pins figured out for M3/4/5.
Is there a way to create a MPG or keyboard short cut to toggle the breakout board pin on/off?
And what hardware device do I purchase and install to interface between the logic voltage and 120 vac?

I'm trying to program a game controller. I initiate KeyGrabber. When I click Start Screen Designer I get an error message Unable to run Mach3Screen.exe. How do I correct this?

General Mach Discussion / fly out screen covers main screen

« on: March 26, 2013, 10:14:13 PM »

I've switched to a larger monitor and now would like to get fly out screen to appear to right of main screen so that it does not cover the tool path or spindle area. How do I do that? When I have either the main screen up or the main screen with the fly out screen there is blank space to the right of the screens.

General Mach Discussion / how to repeat subroutine without adding it mulitple times in gcode

« on: March 19, 2013, 12:11:38 PM »

I am trying to drill a series of holes using a movement of X and Z together to get a hole that is other than 90 degrees from the XY plane. I have selected the holes and have added a subroutine (M98) after each hole's XY coordinate in the gcode. This drills the holes as needed. The XY location of the holes will change and I do not want to edit all these lines of gcode each time the XY of a group of holes changes. How do I get my subroutine to function like the canned drill cycles G81-G89 where the gcode of G81 appears only once ahead of the list of XY locations of the holes to be drilled?
Can I create a 'G81-G89' gcode that I can select from within BobCad or Mach3?
If the answers are in the forum somewhere please direct me to them.

General Mach Discussion / need G code format to drill hole using tangent function

« on: March 16, 2013, 04:58:32 PM »

I want to rotate the router and then drill a hole moving the x and z together using the tangent function. I think I need to have a G18 first to set the active plane to XZ. What is the G code and format to move the X and Z together for this?

FAQs / Jog ok, g code steppers just screech

« on: March 28, 2011, 09:48:43 AM »

I set the steps per to 2000, feed rate at 12. Jog either with mouse or keyboard is ok. When I try MDI and g code the x and/or steppers just screech. It sounds like their trying to run too fast. What did I miss?
