Hey there, I have been having this same issue after about the first month of use.
Here is what I have tried to date with no luck…
2 New circuits for X-Controller Only
Removing the Bulk Head Adapter
Replacement Motherboard from Inventables
Re-grounded my entire dust collection system from the vacuum boot by the router to the vacuum, and to a new 4’ deep earth grounded copper rod.
Battery Backup surge protector
3 different computers
Removed router cord from drag chain
Checked all connections
Ran in environment free of other power tools
LAN Connection to PC
Ferrite choke on USB
I will run 3 or 4 good carves then it will start having the stopping mid carve issue. I just ordered a powered USB hub to try.
I am extremely frustrated with this. I have sunk more time and money into this than I was led to believe that this was going to take to operate. I purchased this machine to give it a task and let it do its thing with out having to worry about babysitting it. Unfortunately, that has not been the case. It happens with random carves. Any more information would be helpful.
This machine was purchased October 2019
