ToolBoard: 2 wires fan, heater fault and how to extrude ?

Pseud3mys

I mean invert A+ with B- and B+ with A- ?

Veti

@Pseud3mys

like turning the connector 180 degrees?
yes that inverts the motor direction

Pseud3mys

yes, okay thank.

R25 (kΩ): 500 ± 3%
β25/85 (K): 3800 ± 2%

I find this for the thermistor.

M308 S1 P"121.temp0" Y"thermistor" T500000 B3800

so I put this, the temp is 12°c when it must be ~19 I think. I have always the fault, do you now what I nead to change ?

Pseud3mys

I send M302 P1 to allow cold extrusion, and I test if the command went good:
"Cold extrusion is allowed (use M302 P0 to forbid it)"

but I still can't use it:

Pseud3mys

I test the "extrudeur 2" here, see it heat 5°c and then it stop.

in the online configurator
https://configtool.reprapfirmware.org/Heaters
click on the beta field and in the popup select slice high temperature.

I connected the 2 wires fan on OUT2 (3 pins) and when I start it nothing happen (I have tested all wiring possible).

how did you configure it? post your config.g

; Fans
M950 F0 C"121.out2" Q500                            ; create fan 0 on pin 121.out2 and set its frequency
M106 P0 S0 H-1                                      ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"122.out2" Q500                            ; create fan 1 on pin 122.out2 and set its frequency
M106 P1 S0 H-1                                      ; set fan 1 value. Thermostatic control is turned off

I put this, directly from RRF config tool.

Veti

did you verify that the fans are working? by connecting them to the always on port on the duet 3 mainboard?

Pseud3mys

@Veti yes, On Vin and GND it work

Veti

@Pseud3mys

change the S0 to S1 for testing

Pseud3mys

@Veti with S0 or S1 It work just when It is at 100% now. But not for all other value it don't work

Veti

@Pseud3mys
some fans do not work with pwm.

Pseud3mys

@Veti I just see that is a 24v fan, I power the board with 12v. But if I power with 24v did the output will go up 24v as well ?

no
see the wiring diagram.

https://duet3d.dozuki.com/Wiki/Duet_3_Tool_Board

the out is 12v

Pseud3mys

ah yes, thank you

Pseud3mys

@Veti have you an idea for the heater fault or the cold extrusion ?

I send M302 P1 to allow cold extrusion, and I test if the command went good:
"Cold extrusion is allowed (use M302 P0 to forbid it)"

but I still can't use it:

Veti

what is the error message in the console?

Pseud3mys

@Veti there are no error message. When I click on the "extrude" button nothing happen

Veti

@Pseud3mys
for the heating. how did you get the error?

you still have not posted your config.g
