Print Speed Not Captured In GCode

[dbongard 0]

I'm sorry if this has been answered elsewhere.

I tried to find anything on this subject but didn't.

 

The Print Speed setting in the GCode generated by Cura does not seem to be read by my Creality Sermoon D1.

Everything else I set comes across, but the speed always comes up as 100mm/s and therefore if I forget to hand adjust it then the print fails.

Is it me or is there a bug in the Creality firmware?

The "F" parameter in movement lines (usually G0 through G3) are the speed in mm/minute.  So if the print speed for a particular extrusion is set at 100mm/sec in Cura then the Gcode line would contain F6000.

The gcode command "M220" is the feedrate multiplier in %.  M220 S90 would set the feed rate at 90% of whatever any line in the gcode says.  It's the same as adjusting the speed with the knob on the LCD and should be reflected in the "fr" field on the Info screen of the LCD.
