Itty Bitty Double FLEX Extruder

OK, lowering the extrusion multiplier is making a huge difference. I have used an extrusion multiplier of .90 in S3D forever and gotten great results. I'm down to .50 and getting ready to go a bit lower yet to get the right print.

I responded in your other thread as well. Check your microstep settings. The 615 value assumes you're running 1/16 microsteps. If you have a RAMPS board, make sure you have all three jumpers installed under the driver.

I have all three jumpers installed, this board is just acting very strange. I may switch it out

So, in desperation I decided to take my RAMPS board apart and start all over.


And then I see that I had three jumpers on every stepper drive EXCEPT the extruder.


Mea Culpa!


Thank you to everyone that helped me!
