Behavior

Hotend pauses for 2 seconds (sometimes 5 seconds) while printing fine details causing blobs
Steps needed to reproduce the problem
- Download and slice Nano 3D Print Test from https://www.thingiverse.com/thing:2887065
Expected Results No hotend pausing on the printed object anytime while printing
Actual Results Pausing for 2 seconds on some of the 3D print test fine objects. Not an issue when PrusaSlicer is used.

Used ABS+ from eSun and yes, I'm underextruding.

Is this a new feature request? Nope, feels like a bug.

It's a problem of overloading the connection between octoprint and the firmware. I've fixed it, but it's not live yet.

Tested with SuperSlicer_2.2.53.0 and the pausing is still there albeit slightly less so. Attached example photo from print sliced in SuperSlicer_2.2.52.1 vs SuperSlicer_2.2.53.0.

Is there anything else to try?

In printer -> general -> minimum extrusion length, there should be 0.035 can you test with a higher value like 0.1 ? this merge small extrusion together up to this distance, reducing the load on the serial port.

The 'minimum extrusion length' was indeed set to 0.035, changed it to 0.1. Still pauses, see image below.

Perfgraph from Klippy.log shows a host buffer at 100%. FWIW: Using a Pi4 and SKR1.3s (2209 drivers).

Should I go higher with 'minimum extrusion length' or try something else?

Removed most octopi plugins and print completes without pausing. Now adding plugins back 1 by 1 to see if I can identify the culprit. Will follow up soon(ish).

After installing 'DisplayLayerProgress Plugin (1 23 0)', the pausing was back though not in the exact same pattern as before. But it seems safe to say this plugin is a major cause. It was installed to enhance the 'OctoPrint-Dashboard' plugin.

Will try OctoPrint-Dashboard next to see if the exact same pattern returns.
