My first post: (I've looked around for this, but can't find an answer)
I'm having problems on my current machine, with stuttering due to buffer underrun I believe.
May be caused by high polygon counts, i.e. short segments in corners and curves.
This happens on my custom machine and also when I send my own files to my M2.
The sample M2 print files (Bigfoot, etc) all seem to move quickly without stuttering.
I get stuttering with USB cable and SD card prints.
In the hunt for a solution, I've seen that Repetier can send a more concise binary stream.
I have yet to confirm an improvement, as this is a sizable time commitment to change firmwares.
But I wonder if Creator has features to help with short line segments?
like G2/G3 creation when arcs are detected (although STL would create many short straight segments during export).
my machine is a custom, Azteeg X3, 542 box stepper drivers, Nema23 motors, jHead
