Revision to Test and calibrate the Z probe

David Crocker

* With the Z probe not close enough to the bed to trigger it, check that the Z probe reading in Duet Web Control is zero or close to zero.
* If your Z probe is of a type that produces a continuous output when triggered (for example IR, inductive, capacitive and switch-type probes), hold a surface below the Z probe to cause it to trigger (or jog the nozzle towards the bed until it is close enough to trigger). Check that the Z probe reading in DWC is correct (about 537 for the Mini Differential IR probe, and about 1000 for most other types).
* If your Z probe produces a short pulse when it triggers (e.g. Smart Effector, Precision Piezo, FSRs with John SL board, BLTouch) then the pulse will probably be too short for you to see. Proceed to the dynamic test.
* If your Z probe produces a short pulse when it triggers (e.g. Smart Effector, Precision Piezo, FSRs with John SL board, BLTouch) then the pulse will probably be too short for you to see. Proceed to the dynamic test.
