Re: Setup and bed levelling

For the benefit of anyone else setting up with a pretend bl-touch who might be reading this thread at any stage:

Configuration.h

#define USE_ZMAX_PLUG
#define Z_MIN_PROBE_ENDSTOP
#define Z_MIN_PROBE_PIN Z_MAX_PIN
#define BLTOUCH
//#define MIN_SOFTWARE_ENDSTOPS

Now, Conditionals_LCD.h forces

// Always disable probe pin inverting for BLTouch
#undef Z_MIN_PROBE_ENDSTOP_INVERTING
#define Z_MIN_PROBE_ENDSTOP_INVERTING false

And without anything connected to the z-max endstop TEST_BLTOUCH() fails and the printer halts.

I worked around this by temporarily attaching an optical endstop to that spot.
