Fade height is off #799

Closed Chukozor closed 4 years ago

Chukozor commented 4 years ago

Description

Fade height is off

Steps to reproduce

  1. update the firmware of my TFT35 3.0 with the already compiled firmware in the folder "Copy to SD Card root directory to update - Unified Menu Material theme" of the last commit 82a47f6f (friday 2020/06/12)

Expected behavior I expect the printer to adjust the height when printing as the G29 told it.

Actual behavior At each boot the message "Fade height off" is appearing, even after a G29 and M500 and a reboot. I use BLTouch v3. I printed 5 squares at each corner of the bed and on at the center : the one at the center is fine (I use BLtouch to Z-Home) but the 4 others are not printed well, some are printed from too high from the bed and some are printed from too low. The fade height was still working fine with the version 0.25.1 I used before (I'm back to this version to print well).

Hardware

TFT35 3.0, SKR 1.3 board

TFT Firmware Version & Main Board Firmware details

TFT35 firmware of commit 82a47f6f in the forlder "Copy to SD Card root directory to update - Unified Menu Material theme" SKR 1.3 board with the marlin version on BTT github for SKR 1.3

Additional Information

When pressing "ABL" on the TFT35 screen, the G29 is processing, but there is no message like it used to be "[....] stored [....]"

It is showing a message about "Fade height 10" on my TFT in 26.1, so I think that it is actually working. Maybe you should check the auto_load_leveling:1 in config.ini. Or, if you are using the "Start gcode" option from the menu, to set the restoration of bed leveling and fade height there.

After upgrading the version it is a good practise to reset the configuration settings from the menu, as they might change the defaults or the parameter storage format.

If all else fails, you may add the restoring of the leveling in the gcode in the slicer settings.

@Tygrys-1 Thank you for your answer. I'm gonna try it.

Hipsta69 commented 4 years ago

I am having the same issue. My auto_load_levelling:1 is set. Also if I go to the custom menu and choose "Restore Levelling" it turns off again straight away

Tygrys-1 commented 4 years ago

Restore Leveling sends M420 S1 gcode, and depending on your leveling method it should enable the mesh. But, any G28 afterwards will disable it again (unless you compile the Marlin with an option to not do so). Of course you have to have a valid mesh stored in eeprom before using M420.

Hipsta69 commented 4 years ago

I use a BLTouch, with the mesh saved to EEprom. In marlin, I have the following enabled:

define RESTORE_LEVELING_AFTER_G28

define ENABLE_LEVELING_FADE_HEIGHT

define AUTO_BED_LEVELING_BILINEAR

The only way I can turn the fade height message off is by running the ABL command (in the touch screen) which I have to do every time I turn my printer on.

Tygrys-1 commented 4 years ago

Do you print from printer's SD or form TFT? If TFT - do you use "Start gcode"? If you use it - how does it look like?

Do you set Fade Height in Marlin (and saved to eeprom) - to what value?

Hipsta69 commented 4 years ago

Sometimes from the TFT, other times Octoprint I don't have the 'Start Gcode' turned on.

I have the G29 command in the start Gcode of Cura but the printer ignores it if I don't run ABL when I turn the printer on.

I cant actually find a setting in marlin (2.0.5.3) to define a height

Tygrys-1 commented 4 years ago

The Fade Height can be set in Marlin menu, somewhere in the Bed Leveling section. There is no entry for default in configuration.

To add Fade Height to your print gcode use M420 Z

BTW, I had Bilinear Leveling before, now switched to Universal (UBL) and this seams to be more acurate and faster.

Is M420 Z in start code in replace of M420 S1 or with?
