Bit drives into bit setter

When I hit “probe” in CC the bit slowly lowers until it hit the top of the bit setter and the led shines red but instead of going up it keeps trying to go down and drives itself into the bit setter.

Is this a bit setter problem or something to do with the Z axis???

If you power up, connect to the machine, go to settings and you touch the ground lead to the BitZero what shows under Active Inputs?

sorry guys I said bit setter and I meant bit zero

Still do what @WillAdams suggested. Open CM and connect but do not initialize. Under the debug you can see if any sensors are tripped. On the BitSetter simply push the button down and see if the input changes.


If the input changes the BitSetter is working. If the input does not change then you likely have a wiring problem. Carefully inspect the cable and where it hooks up on both ends. The same is true for the BitZero take the magnet/clip and touch the BitZero and observe the input change.

If it changes then the BitZero is working. If the BitZero does not change then check your wiring. Since the magnet/clip gets manipulated a lot check that first. If that connections seems good check both ends of the BitZero cable.

Both the BitZero and the BitSetter will eventually time out if their input does not change. In the mean time the Z keeps going down but eventually times out and quits. When a probe is iniated on the BitZero you should be within .5" of the BitZero or a time out will likely occur.

One last bit of trivia about an SO3 is if the BitZero magnet/clip is grounded the BitSetter wont function properly. The two devices are tied together. Check that you clip/magnet is not grounded.

Did you remember to attach the clip/magnet to your spindle/router somewhere?I have forgotten that step a few times.

William;
The only buttons I have under settings are “OPTIONS”, “MAINTENANCE” and “DEBUG”. I checked in all three of those options and could not find Active Inputs. I did see that the BitZero was option was on.

The status light changes to red when touched with the clip.

“Input Pin State” (what I meant by “Active Inputs”) is a section under “DEBUG”:

What shows when you touch the ground lead to the BitZero?

Nothing happens when I touch ground wire but when I depress the button I get a little dot in the “probe/bitsetter” as shown in the screenshot

That indicates that it should be working.

For using the BitZero, the concerns are:

  • is the ground lead electrically connected to the tool
  • does it test as working before probing (showing both a light on the unit and an active input in Carbide Motion)
  • is the correct unit selected
  • are you using an up-to-date version of Carbide Motion

I wrote up a bit on this at:

if you’re still having difficulty, post the specifics of what you are doing at each step with screen grabs and so forth and we can try to look into this with you.

Firstly, I have a piece of acrylic on the waste board that is partially cut (because the machine stopped and has been stopping at random places in the code.

Secondly, all my data is in inches.

Thirdly, I don’t have a measuring tool that will fit under the router but the closest I can come to a measurement is 1" (no where near 6mm).

I hope this helps William and thanks for your patience

Without screen grabs, and a description of what you are doing at each step, I don’t know what to suggest.

Ideally everything one would need to know would be covered at:

(since that is where one ends up when one clicks on “How to BitZero” at my.carbide3d.com)

If you have a v2 BitZero.

The only way I can think of for what you describe to happen is if you have a v2 BitZero, but have configured for a v1 (see the forum link above).

At each step we need to know:

  • what you did
  • what you expected
  • what actually happened

and we need matching screen grabs and photos showing the state of the software and the machine, as well as any relevant files.

Thank you so much for y our patience which is something I lack. I give up, my frustration meter is pegged and I’m done with this machine

Write in to support@carbide3d.com — I’m sure that the folks there can work through this with you.

The BitZero and the BitSetter are 2 different things that share the same wiring back to the controller.

You said nothing happens when you touch the ground wire to the BitZero plate. If that’s true then there is something wrong in the cabling or maybe the machine is not configured for the model of BitZero that you have.

As Will said you should be able to see an indication in that debug screen when the ground wire (clip or magnet depending on model) is touched to the plate.

While on the topic, I found my BitSetter failed because the vibration had the “top contact piece” unscrewed from the base unit but was still sitting loose in the well.
The system was confused until I screwed it back in. Now I make sure it is in tight by turning the exposed top section occasionally.
