Bambu studio, nozzle cleaning, NOT printing the back plate

1 10 089 versin, bambu studio, just installed.
when cleaning the nozzle, it USED to print a front cleaning stream, and then also did back right-half of plate with a cleaning stream, then started printing the object.

i installed the new update, this morning. it is now NOT PRINTING the back right-half cleaning stream? Is something wrong, or is this a change in software?

it does not show up on the PREVIEW either

It sounds like possibly you’re describing a “prime tower” setting that was enabled but is now missing after the update. The setting is located under “Others” in the Preview tab of Bambu Studio. Check to see if it’s been turned off.

See the Bambu Wiki HERE for complete details.

It’s nothing to do with a tower. Even with my non-AMS X1C, there used to be a right angled priming line at the right rear corner that is no longer shown:

I don’t think I’ll miss it as long as there as the lines in front are still there to get the flow started.

you have the correct interpretation. it is not the prime tower.
NOTE, it appears to be doing a DOUBLE PASS AT FRONT now.

as you state, i don’t care if it is not there, as long as it is not an error, and the nozzle does get cleaned with the pass in teh FRONT (I have single pass, i don’t do the flow calibratin).
thanks

This was instituted as a change in the recent Beta 2 release which is now a public release.

Here is a similar question that was answered on github by the developers.
