This is the easiest way to make button pin testing consistent without
renaming all the button pins. Just make a macro especially for testing
if button pins are set, since they are named consistently in the pins
files.
Aim: Test probes in update_endstops only when activated
Changes:
Configurations
Add define for FIX_MOUNTED_PROBE to handle the situation where formerly ENDSTOPS_ONLY_FOR_HOMING had to be set, or lowering the nozzle below Z_PROBE_OFFSET_FROM_EXTRUDER could give an "endstop hit" message.
Add define for Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN to indicate a common situation, that we have a probe but it is connected to an endstop pin
Add some comments
Shift some entries to have related things together.
Conditionals.h
We have a probe (HAS_Z_MIN_PROBE) if one of the pins is defined AND one of the probes is defined.
SanityCheck.h
Add some tests if the probe is connected and if we have defined a probe.
stepper.cpp
Changes to test the probe only when it is deployed (z_probe_is_active).
Test update_endstops() when the probe is deployed.
MarlinMain.cpp
a. set and reset z_probe_is_active in deploy_z_probe(), stow_z_probe() and dock_sled()
b. set and reset z_probe_is_active in the case a z-servo is moved to a defined position. The only remaining unhandled servo move is in M280 where we do not end in a defined position. If you want to handle a probe use M401/402
c. skip deploying/stowing when already deployed/stowed in the dedicated deploy/stow functions.
d. Handle the new FIX_MOUNTED_PROBE in parallel to a servo driven probe/endstop.
To do: In another PR. handle all probes in deploy/stow_z_probe.
Sort out SERVO_LEVELING vs. HAS_SERVO_ENDSTOPS.
If Marlin is blocking the serial input or command queue for any length
of time (for example more than 2 seconds), it needs to send a message
to serial out to inform the host that it is busy. Marlin should only
send these messages out when busy, and preferably not when trying to
print formatted output.
- Remove the forced activation of SDSUPPORT, I guess people may use the ZUM
3D board and not the LCD module.
- Fixed the tab issue within boards.h file.
