Thank you, I upgraded the firmware

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2.2 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-02-11

now fiddling around with the settings. I'm sure I will annoy you guys again :-))

@droftarts said in Totally confused about bltouch setup:

leave the homing files as they are. The probe will be used for G29, G30 and G31.
However, the Y offset doesn’t matter, as you can move X and Y to anywhere you want, because they are homed first. So just m

Ok, thank you thats understood! I think its better to have the z endstop as a security measure. I will try to calibrate the Z offset and then measure the X/Y. Looking forward how the grid measurement will look like.

So,

from my understanding of your config example above, I have to use the bltouch for Z-Homing from now on?

How does the firmware handle this? -> My problem is that the probe is offset -40 something in the Y direction, so after homing X and Y, the probe is "in the air".

My original idea was, to use the probe for bed levelling measurement and the endstop switch for homing. if that is not possible, i have to find another solution

Hey guys,
good morning

Hey guys,

normally I'm not such a terrible noob about tech stuff, but I might need your help.

I have connected a bltouch, and it also selftests after power up.

I have connected the servo pin to PIN8 of my Duett 2 Wifi board (Heater 3)

This is my config:

; Endstops
M574 X1 S1 P"!xstop"                            ; configure active-LOW endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop"                            ; configure active-LOW endstop for low end on Y via pin ystop
M574 Z1 S1 P"!zstop"                            ; configure active-LOW endstop for low end on Z via pin zstop

; Z-Probe
; BLTouch - Heaters
M558 P5 C"^zprobe.in" H5 F120 T4000            ; set Z probe type to switch and the dive height + speeds
M307 H3 A-1 C-1 D-1 ; Disable the 3rd Heater to free up 
M280 P3 S10 I1
G31 P500 X0 Y0 Z0                            ; set Z probe trigger value, offset and trigger height
M557 X25:205 Y25:175 S20                       ; define mesh grid

As you can see I'm still using the old Z-Switch maybe this is the problem. However, I also created a bltouch_selftest macro I have tried inverted and not inverted, but no success here. Measuring the pin, it shows a constant 3.6V, so i take it the PWM output might not be working.

M280 P3 S120 I1;

I have also tried to enter the command via the command prompt but it doesnt help

Any suggestion, where to start? I guess calibrating etc makes no sense, when not even the self-test is working

thanks in advance and have a nice evening

Thank you! That was an easy one

@jay_s_uk said in Fan not controllable - config error?:

n of the active tool not the hotend c

Ok . Sorry for using the wrong words for the fans. I'm a noob

The part cooling fan is connected to the Fan0
The hotend cooling fan is connected to Fan1

If I want to control the fan1 with PWM, I have to deactivate the thermostatic control and add the fan setting to the slicers gcode instead?

M950 F1 C"fan1" Q25000                           ; create fan 1 on pin fan1 and set its frequency   
M106 P1 S1 H1 T60     

changed to

M950 F1 C"fan1" Q25000                           ; create fan 1 on pin fan1 and set its frequency   
M106 P1 S1 H-1      

Hi all,

I have converted a Wanhao Duplicator i3 with a Duet 2 Wifi board.
Basically at the moment I have one issue.
The printer has 2 Fans, one to cool the hotend, the other one for cooling the filament, of course.

• I can see both fans in the jobs and dashboard sections.

• The 60°C turn on value also works as expected.

• However, when changing the cold end fan manually, for example, because I think the radial fan has no need to run at 100%, there is no reaction. (Fan control of the extruder fan works fine however, but this is set by the slicer)

• You can see the screenshot, however one fan is running at 100% in reality, instead of 20%

Am I maybe making a common mistake?

Thanks in advance and

Greetings from Germany

Sebastian
