[BUG] Mesh gets lost after restart

[Arson31]

Did you test the latest release build?

Yes, and the problem still exists.

Bug Description

Old gcodes prior to flashing new firmware seems to work with alex's firmware or MRiscoC's. After flashing this firmware any gcodes sliced from Cura 5.4.0. will only home and will cancel print. I'm not sure if the start gcode in Cura is causing the problem but it can print older gcode just fine. gcodes.zip

Edit: I found the problem, the gcode is expecting a bed mesh but the printer loses it's mesh every time I power off the machine. I save the bed mesh settings in Leveling => Save Bed Mesh & Control => Store settings but mesh doesn't save like alex's firmware or MRiscoC's.

this sounds almost like this issue here

which has led to this pull request here

I'll be posting an updated release soon, and this should be fixed in it.

@classicrocker883 This workaround resolves the issue without having to redo the mesh again.

1. Build mesh

2. Save Mesh

3. Power off printer

4. Power on printer

5. Go to Control/Advanced Settings/Load Settings

6. Then go to Mesh settings and view mesh

[classicrocker883]

for some reason the mesh saves do not load at startup.

For now I simply add M501 after homing in my start gcode in my printer settings from the same post without having to go through the list of steps:

G28 ;Home
M501; Load settings
M420 S1 ;Pull your mesh bed level:
G1 Z15.0 F6000 ;Move the platform down 15mm
;Prime the extruder
G92 E0
G1 F200 E3

I added this to Configuration_adv.h to specifically loading settings (again) and to prevent losing mesh if I change some other setting. It's a cludge, but I didn't find any reason in source code, why mesh is not initially loaded :/

#define STARTUP_COMMANDS "M501"
