I have just went through and tightened, & did maintenance on everything. Main reason I did that is I bought used, and for some reason the machine kept loosing track of where it was, or “shifting” over every time I would try and set it. I would set and zero something then all the sudden ) moves and it misses the bit setter. So the maintenance seemed to work in that regard, but now it just loses connection to the cutter mid project and I have to start over. Any ideas?
Usually if this problem arises after a period of successful usage it is caused by worn carbon brushes — check and replace them?
Talking replace the brushes on the router? Would you think that would cause it to lose connection as well?
When the brushes get worn down they create noise that can cause usb disconnects. Also static electricity causes disconnects. During the cold winter humidity goes low. Even here in East Texas with rain all day everytime I touch a light switch I get a static shock. Usually East Texas has at least 70% RH so static is not a big deal but when you combine rotating bit, dust collection and the air moving you get static. There are a lot of posts on grounding things here on the forum if the brushes dont fix it. However the brushes are #1 on the hit list of things that cause disconnects.
When you get a disconnect you do not necessarily have to start over. If you only have one tool path then you have to start over. However if you have completed some tool paths then open the file in CC and disable those finished tool paths and save the file and reload the new file.

Guy: strongly recommend to have your electrician of choice checked your wiring… There are not enough woodworkers on this planet that we can miss one!

Recommendation: ground the machine, every piece of metal even if it appears to be connected by some rails or what not. And use an high resistance (~1MOhm) resistor to connect to ground, otherwise spikes that are guided to ground -where they belong!- can reach high current intensity in very short time causing high magnetic fields inducing voltage in wiring.

I had this issue when I had my dust collector running as I was carving. Static built up and stopped the machine (heard little static discharges). Since grounding the tubing to the actual dust collector, I no longer have an issue. If you live in a dry location such as I do (Arizona), running a humidifier also adds moisture to the room/garage. Hope you figure it out.
