Fans not working after updating to RRF3.2

These are my fully working fan settings for 3.2

M950 F0 C"fan0" Q500                           ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1                                 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500                         ; create fan 1 on pin out4 and set its frequency
M106 P1 S1 H1 T45                            ; set fan 1 value. Thermostatic control is turned on

Then the firmware is not processing the parameter according to the documentation.

If my setting of 1 is only setting 1/255 of the fan speed, then my printer would be able to fly with a setting of 255.

I am simply following the documentation:

Snnn Fan speed (0 to 255 or 0.0 to 1.0)

Perhaps the firmware treats 1 as a special case - I don't know - I never tried it.

@jay_s_uk I used to have it 1 in RRF2.05 and worked.
I do not think that is the problem either, and tried the 255 too as a value.

No change

From the DWC console do this M98 P"config.g" and see if it reports any errors.

Why would I ignore the documentation?

@fcwilt This is the reply

M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Error: Heater 3 not found
Error: Height map file 0:/sys/heightmap.csv not found
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 255C

I don't know if this error could be related to the fan problem but it cannot hurt to fix it.

Error: Heater 3 not found

You should not be trying to load the height map in your config.g file - so remove the G29 S1 - I doubt it is related to the fan problem but you never know.

It should not matter as I did not change anything in the fans connections. But I added a BLtouch so posting a picture of the wiring just in case you see anything weird.

GPetropoulos

@fcwilt I do not think so either.
But not sure why there is an indication about heater 3

GPetropoulos

@Phaedrux Can you please take a look?

GPetropoulos

One thing I can note for the installation of BLtouch that did not really make sense,
But it does not respond to M280 P3 S10 as I expected for the config,
but it responds to M280 P0 S10.

jay_s_uk

@GPetropoulos
can you post the outputs of the following

M950 F0
M950 F1
M106 P0
M106 P1

Well if it worked before you added the BLTouch I would, as a test, comment out all of the commands related to the BLTouch.

I see one that is wrong for v3.2: M307 H3 A-1 C-1 D-1

As to the M280: When you used this M950 S0 C"exp.heater3" the servo index parameter for M280 is P0 - as you have discovered. The P3 is for v2 firmware.

@fcwilt Why is the M307 wrong?

jay_s_uk

@GPetropoulos its setting the fan pin up correctly.
Can you send

M106 P0 
M106 P1

GPetropoulos

@jay_s_uk 15:18:26
M106 P1
Fan 1, speed: 100%, min: 10%, max: 100%, blip: 0.10, temperature: 45.0:45.0C, sensors: 1, current speed: 0%:
15:18:19
M106 P0
Fan 0, speed: 0%, min: 10%, max: 100%, blip: 0.10

jay_s_uk

That shows that they are definitely being setup correctly in the firmware then.
Can I suggest reverting the installation of the BLTouch to confirm that hasn't caused an issue?

@GPetropoulos said in Fans not working after updating to RRF3.2:

@fcwilt Why is the M307 wrong?

That is only used with v2 firmware - v3 firmware uses a different approach - M950 - to assign pin function.

It's also likely the cause of the heater 3 error message.
