Description of the bug

I've been experiencing an inconvenient problem with the [insert pause at layer] feature from PrusaSlicer.

According to documentation and general observations, it is supposed to pause BEFORE the layer seen in the UI.

Instead, the printer very often pauses AFTER the chosen layer - and seems especially more likely to do so when using the [variable layer height] feature.

Actual result seems output-specific. When experiencing the pause issue; the same model sliced in the same parameters always end up pausing after the layer. But different layers adjustments may pause before.

I can even see the time-remaining timer changing from 00:01 C before expected pause, to some remaining time (00:34 R)... then at the end of next layer, it pauses.

I've been struggling with pausing for a long time now, has anyone else experienced such a problem ?

Thank you, best.

A part with variable layers height :

Should pause before printing overhang. Definitely did not.

If you're looking for help (from a user like me, or a dev), post a project file where it happens for you. You said it's random. Don't make us keep trying till it happens :)

While i was asking for anyone having the same issue, yes so be it. Here is the generated file seen in example above.

Pause_after_layer_L8620.zip

I also did further investigation and can absolutely confirm the M601 command was placed AFTER the targeted layer in the UI - at line 8620.

According to previously shown screenshot, you can see how the pause should have happen before this same layer.

I'm starting to wonder if the M601 command actually got misplaced due to some height rounding error.

Aye, the point to remember really is that the devs know more about what's going on than you or I do, so they tell you what they need in the submission instructions because you absolutely legitimately can't necessarily work it out for yourself. I was just adding motivation that's obvious from the outside perspective. Picture a chain of comments in the submissions where a bunch of people with experience of the problem post "me too!" and a screenshot but no project files. Very frustrating for the devs. The hub is dotted with devs requesting that a submitter post something that's asked for in the guidance, as well as more analysis as you've provided there in your second comment. They're manically busy, so give them what they ask for.
I'm here to find out about problems before they hit me when I'm in a hurry.

@CaptainFalcon92 post the project file, or if you can't post that one, post another one that exhibits the problem.
