Bed Mesh levels are not stored or recovered succesfully after power cycle #117

Closed Ranney1 closed 3 years ago

Ranney1 commented 3 years ago

Description

Bed level (mesh) data is not used after power cycle.

Steps to Reproduce

If this is a Bug Report, please describe the steps needed to reproduce the issue

  1. Flash firmware
  2. M502 > M500 (clear EEPROM, restore firmware settings)
  3. G28
  4. G29
  5. Results of mesh data are visible.
  6. M420 V > Mesh data OK
  7. Power off, power on
  8. Send: M420 V Recv: echo:Invalid mesh. Recv: echo:Bed Leveling OFF

Expected behavior:

Mesh data is restored after an power cycle if data is saved with M500.

Actual behavior:

It looks like data is not stored of recovered succesfully.

Logging:

After G29

Additional Information

Hardware configuration: BTT Mainboard with STOCK TFT

Config and config adv files: I have the same issue with an github version of the firmware without any changes. (latest version, config data for BTT mainboard and stock tft)

Update: Installed latest release (from prerelease-testing' channel: CF5beta-prerelease3-btt-skr-cr6-with-stock-creality-tft-2020-12-29-16-18 .zip (screen and mainboard firmware) ==> Still not working.

It looks like that this is only happening on a BTT board.

Latest update,

After an power cycle, it is NOT working. But after issuing an M501 it is working.

Example: G28 G29 M420 V => OK M500 => OK M420 V => OK POWER CYCLE M420 V => Invalid mesh => M501 => M420 V => All data is ok and restored

Issue closed.. Sorry for this. I have found the problem in an octoprint plugin... Really stupid and did not realised it...

Sebazzz commented 3 years ago

Can you elaborate on that?

Ranney1 commented 3 years ago

Yes, of course. I was trouble shooting and found out that the mesh level is working after ABL, that I can activate it with an M420 V. After some time I found that it was also working if I send an M501 first. So my idea was; it has to work because it is saved Succesfully and can be load successfully. My trigger was that marlin when connecting was reporting 'emty' mesh points. After a while, I found that octoprint was sending an M503 when connecting.(......) I've changed these settings and now everything is working fine (of course). Thanks for help and sorry that it takes your time!

OMG, how stupid can it/I be... 🙈
