Do not enable “coasting”¶
The “coasting” feature is likely to result in poor quality prints with Klipper. Consider using Klipper's pressure advance instead.

Specifically, if the slicer dramatically changes the extrusion rate between moves then Klipper will perform deceleration and acceleration between moves. This is likely to make blobbing worse, not better.

In contrast, it is okay (and often helpful) to use a slicer's “retract” setting, “wipe” setting, and/or “wipe on retract” setting.

Heater extruder not heating at expected rate

I am having a problem with a print failing with “Heater extruder not heating at expected rate” at the same point in the print. I have done a PID calibration with no luck. Checked that the part cooling fan does not effect the temperature. Resliced the file with the print stopping at the same point.

Probably a bad heater cartridge

See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check.

Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.

FIXED MICROSWISS PROBLEMS BY DOING THIS:

recalibrated esteps

cleaned extruder

cleaned hotend

reduced retraction to 0.5mm

recalibrated flow rate

rotation distance

Basically, one tradeoff of using the all-metal hot end is that retraction distances more than 4mm are likely to pull softened filament up into the cool end, the extruder may then "jam" the soft filament in the heat break, when it pushes back down.

I'm now running 3.5mm at 30mm/s speed and I've pretty much solved the stringing problems. Also disregard the micro swiss suggestion of raising the temperatures, 200 is fine.

It sounds like what is happening is possibly related to pulling filament too far back on retractions and into your ptfe/heat break mating spot, and the gears grind the filament because they cant actually pull/push the jam back through.

Thanks to those who replied. If anyone else has a similar problem and stumbles across this, I can't tell you precisely what solved it, but I did the following:

recalibrated esteps

cleaned extruder

cleaned hotend

reduced retraction to 0.5mm

recalibrated flow rate

I had previously done a temperature test with this filament and established that it looked best at 190-200°C, I used to print at 190°C, but I also increased to 200°C for now. I did a brief test at 210°C, but that blobbed far too much. I'd already increased the temperature before my post, so it wasn't the solution, or at least not the only thing.
