Hey team. I have repeated this error 3 times now to validate.
You load up some gcode and at some point in that code, its time to change tools.
Cycle gcode start -> run some stuff -> tool change
So after changing the tool, while everything is still stopped, the touch button is greyed out. No worries though... just stop the cycle. Then execute your Z touch... except... once you click touch -> click the z touch... you get an immediate "no contact with probe" error and the system goes into disable state.
Tried this 3 times with multiple programs same result. This is a bug right?

First place I would look is in the tool change code for a command that turns a signal off or swaps it.

Hi,

Probably not.
What motion controller are you using? Most motion controllers regard a probe move, ie a g31, where the probe does notmake contact as a fail and stops Mach4.
However there are circumstances where you might use a g31 instead of a g1 and you are not expecting the probe to make contact. The controller will stop Mach none-the-less.
The Ethernet SmoothStepper has a setting (Configure/Plugins/ESS/Probing tab) that determines its behaviour when a non-contact event occurs, by default Mach will stop. You may want to change it.

Its an IMMEDIATE no contact with probe error. It does not move even a hint. So its erroring before the touch procedure even starts. I will check that setting... but it is odd.
