Has anyone experienced the error message “GRBL Alarm 4. Probe Fail. The probe is not in the expected initial state before starting probe cycle.”?
I have been using my Shapeoko 5 Pro for months without any issues. Today I tried to use the machine and I got that message while the machine was initializing.
I used the machine late last week with no issues, and made no changes to any set up since I last used it.
Do you have a BitZero? If so, where is it? Where is the groundlead? Are they touching?
If you power up and connect to the machine and go to Settings | Debug does a Prob input show?
What colour is the LED on the BitSetter? What happens if you push/release the button?
I do not have a bit setter.
I’m not sure I know what you mean by where the groundlead is. Could you elaborate?
There is radio button option the the Settings>Debug>Input Pin State window called “Probe/Bitsetter”, and it was selected.
The left LED (Installed in the front right of the machine) on the BitSetter in the idle state is red. When I press the BitSetter the second LED lights up and changes green.
A BitZero has a magnet/clip that hooks up to the router collet nut when probing with the BitZero. The BitSetter and the BitZero are internally tied together and if your magnet/clip is grounded you get an error because it thinks the BitZero and/or BitSetter is activated. So if you had a BitZero when stored people let the magnet/clip dangle and sometimes it hits the frame of the machine and that causes the two devices to be triggered all the time.
