So I was working on cutting the lid for an urn I am making for my mother in laws cat. I had carved the top of the lid and had flipped the part over to hollow out the lid and cut it out. Well I started the cut and it got about half an inch and disconnected. No big deal I thought it happens every once in a while, usually when I shut off my dust collection. My dust collection is grounded and on a separate circuit. Well I shut the machine off and back on. Initialized the machine. And started the cut again. Well it made it another half in inch further into the cut and disconnected. I checked all the grounding and tried again. Same result another 1/2 inch or so and another disconnect. At this point I am getting frustrated. I double check everything. Make sure all the grounding points are tight. Well it has 2 more disconnects and so far I have only made it a few inches on the first cut. I was at a loss as to what was causing it. Out of desperation I made a tiny change to the g code to just see what would happen. I slowed the feed rate down from 90 to 80. That is the only change I made and I had no more disconnects. The cut complete with no issues. Has anyone else had an issue like this? Or does anyone have an idea what might cause this?
Recently had some issues with freezing. Note my Carbide Motion didn’t actually disconnect. It would just hang.
I have nothing concrete to share unfortunately, but is is very frustrating as there’s a lot of misinformation about static and EMI out there.
I had previously many hours of cutting without any issue. The only changes made were the addition of a BitSetter, and a dust collector instead of shopvac. Reverting to the shop vac, I was able to cause a freeze.
I did what we hate when troubleshooting, I made TWO changes at once.
- Removed my BitSetter.
- Clamped ferrite beads on everything (except servo cables). Router, dust collector, Pi power supply, Shapeoko power supply.
I’ve since had no more freezing. But it’s hard to know what actually fixed it. Or, maybe I’m lucky for now and it will come back.
(Blaming static is often the easy way out. When I had freezing, it was one of the wettest weeks/days we’ve had. After my changes above, I’ve since had a long job where I had wood shavings standing on end on the board pointing at the base of sweepy, and no freezing that time.)
I had the same problem about a year and a half ago. I plugged my computer into a different outlet and haven’t had a disconnect since. Worth a shot.
If your disconnects were previously triggered by turning your dust collection on or off that sounds like the suppressor capacitors on the dust collection are old, insufficient or just not present. That might degrade to the point where even running it could cause enough EMI to give a disconnect.
Reducing the feed rate may be a similar issue with the brushes on the router.
I would try using a decent power filter to feed the dust collector and router, or maybe inspect the brushes on the router to see if they’re old and sparky.
edit - Also make sure your router power cable is not routed along the drag chain where it can broadcast noise into the Shapeoko cabling.
It’s a brand new router and brand new shop vac. I do have my router cable routed through the drag chain set aside for it on the pro. I think I am going to work on some additional grounding.
