Help with USB connection to CrossFire

CrossFire ® PRO Troubleshooting
1

I’ve had the CrossFire PRO for the last few months, everything working great, used it extensively to cut out lots of parts.

Now it sat idle for about the last 2 weeks and I am trying to use it and I cannot get Firecontrol and my laptop to communicate. I am running Windows 8 and this laptop is dedicated to the CrossFire (i.e. it also hasnt been used/no new installations, updates etc. the last 2 weeks.) I have the CrossFire Pro w/THC and the latest version of FireControl.

When I plug in the usb to my laptop the green light comes on the control box and I can hear the high pitched humming of the motors/box change but there is no little chime on my PC to indicate a device plugged in (unsure if it usually does it for the crossfire?). I’ve tried all three ports on my laptop, ive also plugged in a mouse on all three to make sure they all work; all good. I’ve also tried using a different usb cord with the same ends on it; no difference. And yes I tried restarting my computer too.

I attempted to reinstall the drivers by following this guide https://assets.langmuirsystems.com/firecontrol/drivers/Windows7-8_ManualDriverInstall.pdf. However “Crossfire CNC” does not show up in the list, the “Other devices” tab isn’t even there… I also checked under “Unirversal Serial Bus controllers” at the bottom since I read a few other posts where it showed up under there… I did however uninstall and reinstall FireControl USB THC Driver using the wizard.

I will reiterate that I had everything working great before; I had to manually install the drivers when I first got it a few months ago but otherwise at the time my laptop and Firecontrol worked as it should. And absolutely nothing has changed with my setup since.

I am not super computer savvy and am really hoping there is a super simple solution that I am missing! I’ve been just beating my head against the wall the past few hours with this!

Thanks in advance guys!

I would connect another computer to it to see if it recognizes the USB device. At the very least, you would get a “unknown device” which would confirm the USB is working.

Thanks, that is actually one thing I didn’t think of trying. Plugged the USB into my wives laptop, still nothing, no chime, pop-up etc. I checked in device manager too and doesn’t show up anywhere… Does this mean the issue could be in the control box??

It’s either the control box or the USB cable. I hope you have a extra USB A to B connector lying around so you can test.

He already tried another cable. That’s why I deleted my post, I typed before reading the first post completely.

Yup can confirm I did try another USB cable, thanks guys. I contacted Langmuir support this morning we’ll see what they say… hope this can be easily fixed as I have a time sensitive job… and rather not go back to cutting out freehand lol…

I am having the same problem, do you mind telling me how you fixed it?

Sorry about the very late reply. I assume you already got things sorted out, but for anyone in the future that has this issue this is what happened:

I reached out to Langmuir support, and Aksel. After explaining my problem we exchanged a few emails back and forth, with him helping me troubleshoot. After this he determined that the issue was the motion control board inside of the control box - they shipped me out a new one at no charge (was less than a year old) and walked me through swapping it out. Very painless experience.

That was over 2 years ago and have had no issues since.
