My bit zero just started acting up. It doesnt stop when it touches the surface when trying to find the Z axis. I have tried both with the ground on and off. Anyone experience this before?
The BitZero will never work without the grounding clip. If you have a multimeter test that your ground wire has continuity. You could just start a probe and the green light is on the BitZero with the grounding clip.magnet and see if it turns red. Also in the later versions of CM connect but do not initialize and in Settings and Debug you could touch the grounding clip.magnet to the BitZero to see if it is activated. I would bet you have a continuity problem with the grounding wire.
Not likely but the BitSetter and BitZero are tied together. Is your Bitsetter got a green light or red. If it is red you will not get a probe on BitZero to work. You can also test the Bitsetter with the same method for checking the BitZero by depressing the plunger and see if it activated in CM Settings Debug. With neither BitZero or Bitsetter engaged is it activated in the debug screen?
Uhh my bitzero works without the grounding clip, I use it anyways but I forget sometimes and it still functions
The way the BitZero works is the bit is grounded when it touches the BitZero. The bit is connected to the router shaft and IF your router case is grounded that provides the ground so maybe yours works. However some routers only have a 2 pin plug which does not ground the case of the router to the ground of the electricity. Some people also ground their ungrounded router with a wire for static protection. Electrical products that only have 2 wire plugs are double insulated from the case so there is no guarantee of ground on the metal case of a router. that is designed so the operator is not shocked by frayed electrical connetions inside the appliance. Plugs that have a 3 wire plug and that ground is connected to the metal cases of appliances.
So if yours works great but that means the router is grounded. If the router body is not grounded the BitZero will never work because it is the bit touching the BitZero and completing the circuit that registers when the bit touches the BitZero. If your router body is not grounded or your forget to plug up your clip/magnet the BitZero will not trigger. So most likely your router is grounded and you can test that by using a multimeter for continunity between the router collet nut and the frame of the Shapeoko.
It works until it doesn’t — eventually there will come a time when the shaft is perfectly centered, and there is an even film of lubricant all around it — and no ground connection.
Solid point will, I’ll make sure to not get comfortable with that.
It works when finding the coerner of the work piece. Its when it comes up out of the hole and tries to find the top of the bitzero is when it enqcounters the problem. Instead of touching the top of the bit zero and finding the top of it. It keeps trying to plunge down.

Did you update Carbide Motion recently? Not long ago I updated motion and I had the same problem, had to reinstall an older version and my problem went away.
