I’m attempting to configure the OctoPrint Bed Visualiser plugin, and having issues with the probing sequence and saving the new mesh The commands I want to use are as follows: ```auto M190 S60 ; (optional) wait for the bed to get up to temperature G28 ; home all axes M420 S0 ; Turning off bed leveling while probing, if firmware is set to restore after G28 G29 P1 ; automatically populate mesh with all reachable points G29 P3 ; Probe again G29 S0 ; Save the mesh to EEPROM Slot 0 @BEDLEVELVISUALIZER ; tell the plugin to watch for reported mesh M420 S1 V ; enable leveling and report the new mesh M500 ; save settings to EEPROM ``` The first “G29 P1” and the “G29 P3” seem to work as intended, but any further G29 commands re-probe the bed from the last position that was measured in the previous command. The steppers will ‘bump’ and complain loudly. Am I doing something really stupidly wrong? My Ender 3 V2 currently has the Ender3-V2-BLTouch-MarlinUI-20221105 firmware loaded. ---

I’m not sure that the Octoprint plugin can work with mesh levelling… You can use it with the normal Bilinear without issue though. ---

If I issue the same commands manually in the octoprint terminal, bypassing the plugin, the same problem occurs… ---

I don’t use UBL myself - I’ve never had much luck with it - however the best I can really do is point you to the Marlin documentation on it: > **[Bed Leveling (Unified)](https://marlinfw.org/docs/gcode/G029-ubl.html)** > > The Unified Bed Leveling System (UBL) provides a comprehensive set of resources to produce the best bed leveling results possible. See the full Unified Bed Leveling documentation for more details. Failing that, you could try and ask your questions in the Marlin discord: > **[Join the Marlin Firmware Discord Server!](https://discord.com/invite/TW5haK93Kg)** > > Marlin Firmware support and development help from the community and core developers. | 12,474 members ---

Is there anywhere I can view/obtain the Configuration.h and Configuration\_adv.h used for building the firmware at [https://marlin.crc.id.au/firmware/Ender 3 V2 - v4.2.2 Board - BLTouch](https://marlin.crc.id.au/firmware/Ender%203%20V2%20-%20v4.2.2%20Board%20-%20BLTouch/) ?? ---

Running into this too, did you ever solve it?
