Cutter Stopped Responding Error

I’ve run into an issue yesterday and today for the first time ever and need help. I have a 4 XXL with a BitRunner Deluxe (Makita router) that I’ve been using for 1.5 years now. During a project yesterday my machine just stopped working all of a sudden during a toolpath. The router also stopped (which was a good thing) and Carbide Motion showed an error Cutter Stopped Responding. I attempted to reconnect but kept getting the same error so i had to restart the machine. I was able to change the toolpaths in CC and finish the project luckily. Jump to today and i am running another project and had the same problem happen again! This time in a completely different toolpath. I can’t figure out what happened or what changed to have this happen twice now. The only thing i did recently was take off the carriage plate to tighten the v wheels and everything is plugged in as it was.

I’d really appreciate any help or insight for anyone here! Thanks!!!

First thing, check the brushes on the router. As they wear down, they can cause a lot of electrical interference.

I have about 10 hours of runtime on the Makita router I am using - would brushes go bad that quickly?

10 hours? No, it should be good for way longer than that.

It is still worth checking the brushes and if visibly worn, replacing them.

We have a blog post on this:

I had this same message a few weeks ago and it was the USB conection to my laptop. While it visually looked ok all it took to fix it was to disconnect and reconnect it and it’s been running fine ever since. It also helps to route the cable so there’s a bit of tension pushing on the connection so the slight movement of the USB connection is eliminated.

I had a similar recurring issue and it was interference between USB port and power port. Moved USB to other side of laptop and hasn’t happened since.

So I’ve been using an anti static hose from Rockler. I read through the article and watched the video and the main take away is that I still need to wrap a bare wire around the hose and connect it to my machine, is that right?

Are you using a normal USB cable or one with ferrite?

10

Would that be for both the USB input to the machine and computer? Also - are you using a normal USB cable or one that has ferrite?

11

I thought that as well but I’ll still take a look.

12

In my case I just disconnected and reconnected at the laptop. I use a normal everyday USB cable.

13

I’m using a USB with a ferrite.

I did just because. X, Y’s, Z, Bed, Dust collector. Ran the ground wires to a rod outside.

Good luck
