[BUG] Fan soft PWM stops extrusion [Hemera] #17197

Closed Mosher23 closed 4 years ago

Mosher23 commented 4 years ago

Bug Description

My part cooling fan is set to start cooling from layer 3. As soon as fan start spinning my extruder [e3d hemera] stops extruding, even the gcode is being send. I disabled fan_soft_pwm and now all is working, but i can’t control fan speed.

My Configurations

Marlin 2.0.5 Skr 1.4 Turbo E3D Hemera

Steps to Reproduce

  1. set Fan_Soft_pwm in Marlin
  2. Use Hemera as extruder (didn‘t verify with other extruders)
  3. Print
  4. when the part cooling starts, extruder stops

No help? I disabled Fan soft PWM and it still stops extrusion.

Initially I was going to make a separate issue since your initial comment said the extruder would work with fan_soft_pwm disabled, and my Skr Pro v1.1 has been disabling E0 upon pwm fan activation regardless of the soft_pwm configs, but your comment from yesterday is in line with my experience so I will hop on this thread and offer to keep the issue consolidated unless requested.

The last functioning revision was 1.0.1 but I was not actively tinkering with the printer for 1.0.2-1.0.4 releases.

I’m currently away from the computer but I will post zipped configs when I can. Though I have tried both BTT TMC5160 v1.2’s and Watterott TMC5160 v1.1’s that have been verified to be functioning.

I can update with verbatim output of M122 output as well, but for now I can say that all drivers are shown as enabled prior to PWM fan being enabled and then E0 showing as “false” when the fan kicks in.
