Marlin 1.1.5

[Roberts_Clif]

Upgraded again from Marlin 1.1.4 to Marlin 1.1.5 was hoping that they had fixed, the problem that after It Auto homes while displaying CUSTOM_MACHINE_NAME Z-axis will rise changing the display to " Endstops Z " or "G28 Z Forbidden"

Problem still exists See Marlin 1.1.4 this Forum.

I have a unique problem It involves "Endstop Trigger reporting"
I get an error Using a Proximity sensor TL_M3W 'NPN' NC as a Z-Axis endstop.
using these lines of code.
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
#define Z_CLEARANCE_DEPLOY_PROBE 10 // Z Clearance for Deploy/Stow
#define X_PROBE_OFFSET_FROM_EXTRUDER 10 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER 25 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.5 // Z offset: -below +above [the nozzle]
This allows me to home then raise Z-Axis 10mm for a clearance of 10.5mm
When I Auto home everything works up to home, the "Z Clearance for Deploy/Stow" parts finishes I get the error " Endstops Z ". I Believe that because the Z-Axis homed, then rose to the Clearance is why I am getting the error.
The printer Prints Fine I can see nothing that causes a problem, except the Display " Endstops Z "
Now when I use this line
#define Z_MIN_PROBE_ENDSTOP
I get no errors, though I can not get the Z-Axis to Raise to my wanted clearance of 10.5mm.
This works completely in Marlin v1.1RC8 renamed to HICi3 v1.1RC8

I revert to the Previous version of Marlin-RC8BF-HICi3 it works Perfectly.

Marlin 1.1.5 using M500 causes CRC errors.

[Roberts_Clif]

Marlin 1.1.1 - Marlin 1.1.5 using M500 causes CRC errors.
Not an error, looks like it is just a Cyclic Redundancy Check that is stored with the data for testing.

configuration_store.cpp

// Report storage size
#if ENABLED(EEPROM_CHITCHAT)
SERIAL_ECHO_START();
SERIAL_ECHOPAIR("Settings Stored (", eeprom_size - (EEPROM_OFFSET));
SERIAL_ECHOPAIR(" bytes; crc ", (uint32_t)final_crc); //Example "Settings Stored bytes; (451) crc 42816"
SERIAL_ECHOLNPGM(")");
#endif
------------------------------------------------------
#define EEPROM_WRITE(VAR) write_data(eeprom_index, (uint8_t*)&VAR, sizeof(VAR), &working_crc)
#define EEPROM_READ(VAR) read_data(eeprom_index, (uint8_t*)&VAR, sizeof(VAR), &working_crc)
------------------------------------------------------
const uint16_t final_crc = working_crc;
------------------------------------------------------
EEPROM_READ(stored_crc);

Reverted back to Marlin 1.1.5

[Roberts_Clif]

At this point I have re-flashed Marlin 1.1.5 too many times to count, and have made only minuscule changes, and had but forgotten about this problem.
Until I ran across this line of code " #define Z_HOME_BUMP_MM 2"

Marlin 1.1.5 after Auto home while displaying CUSTOM_MACHINE_NAME Z-axis will rise changing the display to " Endstops Z " or "G28 Z Forbidden"

Well I have no explanation, thou it has stopped displaying. I believe that in the following line of code lies the solution thou.

#define Z_HOME_BUMP_MM 5 // changing from 2 to 5 would raise the z_home Bump above the Z probe sensor level thereby eliminating the errors.
