M600 has a delay

Snapmaker 2.0

Hi,

I am about to produce a 3D print with a color change and with the single extruder. I have added M600 for a color change to the corresponding position in the GCode. Unfortunately, the change is only executed much later than it is programmed. Is anyone familiar with this? How can I rectify the error?

Thanks a lot.

Never heard about a delayed filament change.

Whilst on Orca Slicer preview and from the GCode that the colour change (M600) was issued a couple of lines earlier. The same occurs when changing the other way

Hi, no i didnt got it resolved yet. I figured out, that it is about 5 mm of filamentextrusion.
You can put the M600 a little bit earlier and it will work.
