M376 and where to use it
-
SO I put my G29 S1 command to use mesh bed leveling at the beginning of my bed.g file.
Do I put the M376 H10 to taper bed leveling in the same bed.g file? or somewhere else?
Do I put it directly after the G29 line or as a last step in the file? The instructions dont specify where to put the m376 -
I have CURA set to do a G32 at the beginning of every print so I assume I would put the M376 H10 at the end of the bed.g file?
-
I would put M376 in config.g since it only needs to be set once.
I don't think I would want to load the heightmap at the start of bed.g but I guess it would depend what else is happening in bed.g. If loading the heightmap is all you are doing in bed.g then that's fine. If you were doing auto leveling, you wouldn't want the mesh loaded until after.

@phaedrux So just put my G29 s1 and M376 H10 at the end of the drive section?

@57buick said in M376 and where to use it:
So just put my G29 s1 and M376 H10 at the end of the drive section?
Yes to M376 H10, but G29 S1 shouldn't go in config.g. You only want to enable the heightmap after you have homed the printer. A good place for it would be the end of homeall.g or in your slicer start gcode after homing.

@Phaedrux So just want to verify where M376 would go in this macro
I Assume at the end? I have not tried it but am in the middle of a 175mm tall print that I would have rather tapered off..
Thanks,

That looks fine. You can send it whenever you need really.
-
@Phaedrux When you say you can send it when you need.. can it be sent after the print starts??
Thanks -
Yes you can send it after the print starts, though I'm not totally sure how it will behave. Since it's a taper starting from layer 0, the best time to send it is at the start. but If you're just wanting to stop the taper anyway, I don't see why it would be a problem to send it mid print.
-
@Phaedrux Thanks! Seems to work as expected in the macro! Good to know if I can send it any time as well. Thanks again!
