Cooling fan 0 generates M106 S8

Sat May 01, 2021 1:12 pm

Settings:
Layer 1 has Fan 0%
Layer 2 has fan 70%.

End result is gcode that sets the fan to 3% (8/255).

This is generated before startup script:

Code: Select all

G90
M82
M106 S8
M140 S40
M190 S40
M104 S200 T0
M109 S200 T0
What am I missing?

This offset of 8/255 seems to carry on through the whole job, 80% becomes 83% and so on. It does not occur always but most often. Hadn't noticed this ever before but haven't really had to until now that I needed to add minimum level for my new Duet based printer as my blower fan didn't co-op well with Duet's PWM at low duty cycles.

Can you attach your G-Code file?
