Here’s a strange one. Though the WiFi coverage in my workshop isn’t bad, I prefer having a wired network because I often work on Fusion while carves are going on and also stream music, etc. and I like connecting to the BB controller via ethernet because I get the 3D preview, etc. It’s nice to have most of the gig bandwidth. However, whenever my X-50 Woodworker (PwnCNC 220V spindle) starts a cut my Mac loses connectivity to everything. The internet and even the wired connectivity to BB controller. If I want to pause the carve I have to have the mini-display that came with the system connected as well. And it’s direct connection stays solid because it’s not ethernet. There is a small NetGear ethernet hub connecting the units.
I’m thinking it must be something to do with the spindle motor throwing spikes on the power. Some suggestions:
Make sure you’re using a good quality Ethernet cable.
Keep the Ethernet cable away from the power cords (like don’t wrap them up together with cable ties).
If you weren’t using a 220V spindle, I would suggest not plugging the spindle and electronics into the same outlet and/or power strip. But, they must be separate, right?
Try some tests: Does the network go down when you just run the spindle without moving XYZ axes? Does it make a difference where the spindle is in relationship to your Mac or your hub?
SOLVED. My PwnCNC came with a cool IOT power strip that turns on my water-cooling pump when I plug it into the “Normally Off” plug. There is also a “Always On” plug that I’ve been using. Next to that is a “Normally On” plug that turns off when the controller is triggered. I had stupidly plugged the power supply for my ethernet hub into that outlet… Duh.
