CR-10S Pro + Octoprint = No Auto-leveling?

#1

I've got the latest version of Octoprint running on a Raspberry Pi 3B today, interfacing with my Creality CR-10S Pro. It works great, except I noticed something:

If I slice a file in Cura and delivery it via MicroSD, when I go to print it will always go through the Auto-bed leveling first. However, if I print through Cura, using the Octoprint plugin, directly it goes straight to the print (after homing to the center) with no auto-leveling procedure.

Is there a setting I can use to have it follow the same procedure (auto-leveling) before each print?

This is using:
Cura 4.3.0 on Windows 10
Version 3.5.10 of the Octoprint plug-in
Octopi 0.17.0 (Downloaded from this site earlier today)

Yes you can either add a G29 to your start gcode in cura


or remove the start gcode from cura and use a start gcode in octoprint with G29 in it.

Thank you so much for the reply! A few clarification questions:

  • (before this change) Why does printing via Cura->SD do the ABL but Cura->OctoPrint not?
  • There are already a bunch of GCODEs by default, one of which uses M420 for ABL - should I place this GCODE in place of that one?

I don't know to be honest

Yes. M420 S1 uses the already saved mesh from your printers eeprom while G29 starts a new bed leveling and uses the new created mesh.

It should look like this afterwards
