gcode for quieter printing

[Nargg]

Thanks Graham. Interesting that Lisa provided an example on that command and not any others. The example appears to be a lower value too. Hmmm...

I just realized that I missed answering another part of your question.

Not sure that I particularly recommend them but I use the default value that FF uses in Flashprint and have never had reason to alter them. I used these same values in the startup section of other slicers.

M907 X100 Y100 Z40 Axx Bxx where xx = 80 for an active extruder and xx = 20 for a standby extruder.

If I were to attempt to optimize these, I would reduce them until I started getting skipped steps and then bump them back up 5 or 10 to give some safety margin.
Due to the nature (poor design) of the standard Dreamer thermocouple wiring, I would be tempted to get the A and B values as low as possible to let the motors add as little heat as possible. I have modified my thermocouple wiring so it is not a real concern in my case.
