Resolved? Repeatable z=0 after repeated trigger hight calibration random results som good prints many bad due to the initial layer height
I remounted the BL Touch to make sure the bottom collar was 8.3mm above the table. I reset the trigger height using Max Nippard's 10/27/2018 suggestions on the https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe page His suggestions made much more sense than the page content. My only issue was that he stated, "your trigger height result (should be between 0 and 1mm, depending on your printer." My trigger height was 2.16mm. But it works! I also changed my P5 Back to P9.
A constant error that does not affect the ability to print except mesh values do not seem to be used
This error was caused by G code script added by my slicer Simplified 3D after editing that error is gone.☺
Heating fault at first just when heating from room temp. E3D Lite hot end with 24 v cartridge. ran Autotune but the error continues
?? It seems fixed: I replaced the thermistor and changed out the aluminum block for a copper one. Copper maintains heat better but for the same reason, It takes longer to heat (pure desperation). I then ran autotune again remembering to do an M500 afterward. A word of caution to anyone reading this and deciding to use the M307 for heater parameters in the config.g; Do not forget to comment out the M307 for that heater in config-overide.g If you want the new settings to be used by the firmware.
I would appreciate comments on the 2.16 trigger height.
Thank you very much for your direction.
