The Setting from Autolevel in EEPROM don´t get stored.

[Experte9]

Steps to Reproduce

1. Set the hook on Autolevel
2. Press the Save button
3. Go to Terminal
4. Write M501 in terminal
5. Go back to EEPROM and u see the hook is gone

Happens also if u trun off Printer an Octoprint for more than 10 min.

In my case (i´m using a Ender 3 S1) i´m not able to Enable Autolevel using OctoPi. The Firmware crashes and then restarts. Edit: It seems to be working now.

Using also a S1, works fine so far did u read this? CAUTION! It is confirmed that Creality is selling some S1 with a STM32F4 chips, The current firmware version is incompatible with this SoC, only boards with STM32F1xx are supported. https://github.com/mriscoc/Ender3V2S1/releases/tag/20220330 Also make sure u donloaded the right .bin

[daniel-volz]

Yes, Board is STM32F103, Firmware works as it should, Autoleveling is working for me, recognizable by the two blue lines under the Z symbol during printing.

Using the latest Release for ender 3 s1. Activating it via EEPROM Editor in octopi Kills the printer and reboots the firmware

Which Bed Leveling GCode do you use?

[Experte9]

I dont use any GCode for leveling, only do Leveling with the display. Then I print, havent look for the blue Lines under Z, but i think i never saw it. Thats my Start G-Code:

_M104 S185 ; preheat extruder temp M140 S{material_bed_temperature_layer_0} ; set bed temp M190 S{material_bed_temperature_layer_0} ; wait for bed temp M109 S{material_print_temperature_layer0} ; wait for extruder temp G28 ;Home G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up G1 X10.1 Y20 Z0.28 F5000.0 ;Move to start position G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up

Okay, i´m using the update Leveling Button in Octoprint: See Bed level visualizer support But with my own GCODE for leveling in the Plugin.

I can confirm your issue.

In my case the printer restarted after enabling auto level in EEPROM Manager in the past. Now the printer doesn't hang up anymore when I activate it, but it doesn't stay active, you´re right.

Any G28 / Homing will disable the auto leveling, that's why a M420 S1 should follow after the G28. I just tested with Octoprint:

G28   ; Autohome
C29 N3 T0   ; Set 3x3 mesh and auto leveling bed temperature to 0 (only for test)
G29   ; Start auto leveling (for have a valid mesh)
M500   ; Save the mesh to the EEPROM
C108   ; Quit the Mesh Viewer

Now with a valid mesh in the EEPROM I go to the EEPROM editor Plugin Press Load to load a valid set of parameters from the printer to the plugin Go to the Autolevel section of the plugin Check/Uncheck Enable and press Save The z-offset icon changes color to confirm active/inactive auto leveling.

Go to the bed visualizer plugin and press Update Mesh now And I got the graphic representation of the mesh

For the bed Visualizer I have this configuration:

M155 S30        ; set temperature reporting delay, use a value longer than the time it takes for your leveling command to complete.
@BEDLEVELVISUALIZER ; instruct plugin to start recording responses from printer.
M420 V                  ; get the mesh value
M155 S3         ; set the temperature reporting delay back to a shorter time span.

Now with a valid mesh in the EEPROM I go to the EEPROM editor Plugin Press Load to load a valid set of parameters from the printer to the plugin Go to the Autolevel section of the plugin Check/Uncheck Enable and press Save The z-offset icon changes color to confirm active/inactive auto leveling.

After you did this, please try: M501 ; Load Setting from EEPROM OR turn off Printer and Octoprint for minimum 10 min.

Then go again to EEPROM editor Plugin. Is the Autolevel option still checked?

Edit: I will try to Print with the new Start G-Code: M104 S185 ; preheat extruder temp M140 S{material_bed_temperature_layer_0} ; set bed temp M190 S{material_bed_temperature_layer_0} ; wait for bed temp M109 S{material_print_temperature_layer_0} ; wait for extruder temp G28 ;Home M420 S1 G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up G1 X10.1 Y20 Z0.28 F5000.0 ;Move to start position G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up

Maybe not because in 10 minutes the printer disables the steppers motors then for do any movement safely it is necessary to do a home and any home disables the auto leveling.

Thanks for your explanation, it's not a bug, it's standard in the Marlin software. Maybe the whole thing will be added to the documentation, I didn't realize that this function would be deactivated by auto homing.

Does it maybe make sense to set RESTORE_LEVELING_AFTER_G28 for the Ender 3 S1 in Marlin? https://marlinfw.org/docs/gcode/M420.html

[mriscoc]

RESTORE_LEVELING_AFTER_G28 could cause problems.
