Carbide Motion not connecting to cutter on specific lapotop

I recently tried to connect my Shapeoko HDM to my Dell laptop and I keep getting a Cutter Not Found message after around 10 seconds of clicking connect to cutter. I checked the cables, restarted my laptop, and redownloaded Carbide Create completely, used a different USB port, but the issue still remained. This problem is on the laptop that I usually use to control my Shapeoko too, and had worked perfectly before. I tried connecting on a different laptop and it worked normally, so I’m not sure what the problem is.

All the usb ports on the laptop that won’t connect are working, and so are the cables. I did recently get a motherboard change on the laptop but all the settings and program files remain the same and everything else works normally. What could be the cause of this issue?

I also noticed that when I press connect to cutter, the red stop button does not appear like my other laptop does when the ethernet cable is not connected to the control box and acts as if nothing was connected to the laptop

Try changing the com port on the PC?

There is a basic page on troubleshooting connection issues at: Can’t connect to machine or jog - Carbide 3D

Things to check:

  • power supply plugged in — it lights up after being plugged in and stays lit with a steady light?
  • power supply connected to machine and switched on — the in-line switch is small and easily missed (try toggling on/off a couple of times) SO4/Pro — machine power switch is switched on and lights up?
  • machine boots up, controller lights up with power, lights flicker on/off, motors lock?
  • machine connected to computer using USB — computer registers USB device? red/green/white lights on controller begin to blink signifying USB communication?
  • How is the USB connection being made? 6’ or less is recommended, and poor quality adapters cables are known to be problematic
  • Are there any conflicting devices in the USB Device Tree? Even a pair of Bluetooth speakers can conflict
