Dual extruder bed leveling gcodes missing

I recently bought a dual extruder for the sm2 and had quite some bed leveling issues. Therefore I used the great Klicky probe guides in the forum + the models on printables for the dual extruder. Now that that was working It was way better but still not great with a 6x6 mesh. Wanted to do a 11x11 then but found out that the gcodes for leveling are not available for the dual extruder.

It would be really great to have 11x11 bed leveling without the automatic z offset on the nozzles at the end would be great to Save some pinched fingers.

@Jade I do know you have loads of stuff on the plate with the u1 coming. And i am in the first batch of Kickstarters there as well, but it would be still really great to get some updates/informations for the s2.0 as well (want to utilize the bigger build volume)

Here is how to do a leveling with a greater matrix:

But honestly I’m not sure how to proceed with the nozzle offsets, but it seems you know the way to go.

Some additional info:

Hello fellow Austrian :slight_smile: thanks for the fast response.

The g1029 command seems to only work for the single extruder. And It seems that there are no commands for the dual extruder publicly available.

It seems that at the moment bed leveling with the dual extruder is only possible via the macro on the screen.

To complete the information, here is the reference for G1029:

Welcome from Linz :wink:

In theory this should be an easy fix to the firmware.

I have to retry with a fresh GitHub clone if you are willing to use a custom firmware from a stranger..

My recent changes made it impossible to run on a stock machine..

More reference:

And, sorry for the confusion, it’s a older topic :wink:

I think I read somewhere, that the bed isn’t stable enough in the corners to calibrate with the nozzle directly touching. That’s the way the do it on the artisan. Therefore they only do the z offset calibration in the middle of the bed with the nozzles, the rest with the sensor. As I use a Klicky probe I would need the z offset in the end anyways.

So you would make the g1029 work correctly? I mean in my opinion it is something that snapmaker should actually bake into the firmware themselves. As the sell the dual extruder explicitly for the sm2 as well and I think it is fair to assume that the same capabilities are available for the upgraded part as well.

Off topic: Just installed the bracing Kit and thought it would take me an hour or so. Actually took me quite a bit longer :sweat_smile:

Greetings from nearby Vienna :wink:

Not sure if I am able to implement this. If it’s easy enough I guess it would be possible.

I will report back..

No success till now, I asked the Devs about but I’m not sure if there will come anything back :smirking_face:.

I think it would make sense if they implemented the 11x11 in the gui as well. This way the user can just choose whatever fits best without having to mess with gcode commands.

It would also be nice if they gave us the option for a pause between leveling and z offset calibration then we could safely remove our clicky probes.
