BL going in wrong z direction #82

Closed veevee2 closed 4 years ago

veevee2 commented 4 years ago

Hi, I'm using the master source from 8/5/2020, and enabling the bi linear leveling for a piezo (FIX_MOUNTED_PROBE)

G28-Homing is ok : every axes goes to the right direction, even by remote control panel. But G29-BL try to probe in the wrong z direction : it goes higher and higher. I see no option related to the z direction of homing : what could be about related please ?

Thanks, Olivier

I finally found the reason, but not a so clean solution. Whatever the "#define Z_MIN_PROBE_PIN 11" I add in configuration.h (11 is a pin slot available and connectable on the trigorilla 1, it's 5 on a trigorilla 1.1) : it's overriden by the include pins_TRIGORILLA_14.h which set "#define Z_MIN_PROBE_PIN 2"

I modified pins_TRIGORILLA_14.h but don't like this way, any cleaner solution ?

Hi, I am not using this mod for BL Touch (but the original Marlin). I have just made a diff with mine (using BL touch also). The main difference is this line commented: //#define Z_MIN_PROBE_ENDSTOP_INVERTING false // set to true to invert the logic of the probe. Could you give a try? Edit: BTW, I did not find any #define Z_MIN_PROBE_PIN initialization in my Marlin.... :/

Hi, Finally the problem is solved : too much sensibility of the piezo cause this continus z move until the sensibility is better adjusted. Since that : everything Work great (an accuracy is impressive)
