@petrzmax said in Inconsistent Extrusion?:

Hi again!

The parts have come yesterday and I have rebuilded and recalibrated my extruder.

As You can see its much better and almost perfect. Almost, because now new lines have appeared. From my research I know that it's related to stepper settings. Changing TBL and TOFF had impact on this pattern. The question is does somebody made this lines disappear on TMC2660? I know that on prusa printers they can modify stepper waveform to make it disappear, but is there a fix for us, Duet users? I'm already on 0.9 deg motor with titan Aero.

I would try increasing or decreasing the stepper current a bit and see if that helps. You could also try to play a bit with the voltage regulator on your power supply , that changes the magnetic fields to be less ... interfering maybe and maybe gets rid of it.

Can you explain what you did when when you rebuilt the extruder? I´m chasing similar inconsistent extrusion problems to what you had before.

For a fan "full range" is usually limited by the lowest voltage the fan will run and start at (mind you those specifications are without any static pressure from a fan duct). But even at the lowest speed it will be running a lot faster than 1% of full speed.

In this case 4.5V, so you could try to measure the voltage and pick the frequency that gives you the combination of a voltage close to 4.5V for the lowest setting and smooth running. Then you need to decide if you want 1% to be lowest possible speed, or if you want to approximate the % setting to % of RPM, say having 30% equal to 4.5V and the lowest possible speed.

@phaedrux Thanks I have played with these settings and it's a bit better now. Thanks for help guys 🙂
