GRBL Alarm 5 Probe fail. Probe did not contact the workpiece within the programmed travel

Trying to use the bitzero to set my zeros in the lower left corner. The tool probes from right to left in the bitzero pocket, then stops and throws the error above in Carbide Motion.

I am only using the bitzero as I do not yet have a bit setter (on order).

Do I need to have the bitsetter to also use the bitzero?

Thanks,
Bryan M.

No, you don’t need a BitSetter to use the BitZero.

Did you configure for a BitZero v1 or v2?

See:

Using/verifying the BitZero

Here is how I check out the functionality of the machine/BitZero: first check that you have sent the correct Z-axis configuration This can be easily done by jogging down to the wasteboard surface, setting zero, then using the Rapid Position command to lift 6mm above the current zero — measure how much the machine moved — if it’s wrong: go to the MDI and send $$ and check that the Z-axis steps/mm match your machine setup: Belt-drive: 40 Z-Plus: 200 HDZ: 320 ​ ​c.f., Then, clamp a sui…

Hi William.
I did configure for BitZero v2.

I am a new CNC user so can you explain how I go to MDI to verify Z-axis steps/mm?

I do not have the MDI configuration in Carbide Motion v6.18. Can I see these settings somewhere else?

Where do I check the GRBL configurations for Shapeoko 3 XXL Belt Z-Axis?

Thank you for your help.
