@guerty25 said in Uneven Layer Extrusion:
M350 X32 Y32 Z32 I1 ; configure microstepping
the duet wifi only supports interpolation at x16. this does not work.
-
@Veti I'll try dropping the interpolation part, but I was under the impression that the firmware would just ignore that anyway. I'm in the middle of a long print so I'll give it a shot when it's done.
-
try x16 with interpolation. it should give you a smother result.
-
@Veti I tried x16 with interpolation. It might be a slightly smoother, but I'm seeing very similar results.
-
Is this at 100% infill....a solid block
Post your gcode file here if you can -
@percar I’m away from my computer but the block is 10% gyroid if I remember correctly.

Hi there, just saw your posts. Did you fix your Flex3Drive extrusion issue? If not contact me directly (Im Jason at Flex3Drive) and I will assist you.
-
Hi @jason_f3d I spoke with you on the Flex3D Discord channel. I was the one that had play in the gears and had to scale the printable G5 parts down to 93%. Since then I also ordered a shorter flex shaft as I was still getting very slight unevenness.
-
@guerty25 OK lets take another look, because scaling down to 93% doesn't work in the math. Any adjustment to mesh in self printed parts by way of shrinkage is only to take up a couple tenths of a mm at most.
Did you mean 99.3% ? Either way, contact me directly and we can set this right.
