So ive been dealing with disconnects for nearly 2 years using the shapeoko. If i use pine i am fine but if i use something like cedar or mdf i get disconnects, I have since grounded my dust collection and i can manage the dust collection disconnects but the problem im really concerned about is my disconnects when the system isnt even in use.
Right now if i have no jobs running and the machine is sitting by its self and i use my sanders or compressor or miter or table saw there is a chance my machine disconnects in the other room. Ive stopped working in the shop when the machine is running to minimize this but i have no idea how to tackle this problem.
I didnt submit a ticket for this as the last 2 times it was not able to be resolved. The last time i talked to someone they suggested i buy ESD mats to put under my machine but i couldnt find anything under 500$ Canadian.
Some people have had luck with surge protectors, but it’s hit-and-miss, I suppose depending on exactly how the manufacturer designs things. Ferrite chokes can help as well, you can get ‘add-on’ chokes you could apply to your existing power cords:
My original SO3 XXL had disconnects. The problem with mine was the original controller had a flakey usb connection where the usb cable plugged in. I solved it by putting a wire tie holder that has adhesive and wire tied the usb cable so it had a straight shot into the controller so it did not hang by its own weight. That solved my disconnect problems. I eventually replaced the original board and keep as a spare because I wanted a BitRunner and the original boards did not have the connector for the BitRunner.
If it is noise from the circuits that can be hard to diagnose without an o-scope. However those cheap little circuit testers can help if your polarity is reversed or there is not real ground.
