Unable to jog cutter

Just finished assembling my crossfire and when I plug it in to my laptop and turn it on it is not jogging or responding. Tried restarting both and am in mach3. New to this stuff so assuming it is newbie error.

Did you follow the setup steps in the user manual?

Hi Jerrad,

When you flip the power switch on the CrossFire, do you get holding torque at the motors? You will hear a slight humming coming from the motors when you turn the power on. This test verifies that there’s not something wrong with the Electronics and more likely something to do with Mach 3/USB connection. For what its worth, we test every single electronics enclosure to verify that it works properly.

Some simple things to check:

  • Make sure USB cable is installed into both your laptop and the CrossFire
  • Make sure Mach 3 isn’t showing any errors
  • Verify that you have inserted the CrossFire plugin into the appropriate Mach 3 folder. The plugin can be found on our downloads page.
  • Make sure to hit reset in Mach 3 once you have it opened

I’m pretty sure, will go through it again to double check.

I hear the buzzing noise, that’s a relief that it’s my fault.


That’s great to hear, Jerrad. Please check out the Cutting Tutorial #1: Installing Mach3 on our tutorials page located at http://www.langmuirsystems.com/tutorials

You’ll want to make sure that you have downloaded both CrossFire Mach3 USB Motion Controller Plugin (v1.0) and CrossFire Mach3 Profile (v1.1) from our downloads page (http://www.langmuirsystems.com/downloads) and follow the instructional video (Installing Mach3) for instructions on placing these files in the correct folder in the Mach3 directory.



Hi Jerrad- last we talked you had figured out the issue and were able to jog the machine. Curious to know if you’re cutting yet?

Have not cut anything yet but have ran some items through the machine with the cutter and seems to be doing everything perfectly.
