Hello everyone
I just tried to use the virtual heaters 100,101,102 to control a fan (no. 0) as follows:
M950 F0 C"duex.fan3+duex.fan4"
M106 P0 T45 H100:101:102
Unfortunately I get the error "Sensor number out of range". Is there a new way on how to utilise the mcu temp and driver temp for fans?
I now get the same error during homing on RRF 3.0beta12.. DO you know the reason for that?
@dc42 Thanks for the last update. It solved one issue with the BLTouch v3.
The biggest problem I had was that I needed to invert both pins from:
M950 S4 C"exp.heater4"
...
M950 S0 C"exp.heater3"
to
M950 S4 C"!exp.heater4"
...
M950 S0 C"!exp.heater3"
That solved all issues. I've just discovered that they needed to be inverted for PWM.. 
@dc42 Do you have any news regarding the issue resp. could you replicate it?
@dc42 Duet Ethernet 1.02 or later + DueX5
@dc42 Having seen your post I also checked the frequency on a multimeter and indeed it shows 49.9Hz when using S4 or P4 Q50 resp. 499.8Hz when using P4. However, I can't get the servo running with the new firmware. Sometimes it moves once but doesn't execute the other commands. It works perfectly fine on RRF2 though.
I'm going to borrow an oscilloscope and I'll tell you when I find sth interesting. But I'm quite certain the issue must be software related..
Hi dc42,
unfortunately servos also don't work on the newly updated firmware. They move slightly on M950 P... (500Hz) but not on M950 S... (50Hz). Also using the Q command makes no difference.
This is the code I use to move a servo on the new RRF 3:
; The next two lines are in config.g:
M950 P4 C"nil"
M950 S4 C"exp.heater4"
; The next two lines are in a macro gcode:
;cutting code
M280 P4 S20;reset
G4 P10;wait
M280 P4 S170;cutting
G4 P800;wait
M280 P4 S20;reset
G4 P300;wait
;cutting code end
Would be great to here if you have any idea why that is? Thanks!
Ok I quickly found the solution myself: I had to free up the pin from the Y axis even though I didn't assign the endstop to it:
M574 Y0 P"nil"
I am currently trying out RRF3. I wanted to free up the pin used for homing my B axis so I could use he same endstop for the C axis. But I always get the message that the pin "ystop" is not free.
I tried
M574 B2 P"nil"
M574 C0 P"nil"
M574 B2 S0 P"ystop"
for the use as the B axis and vice versa for the C axis, but it is not working. What am I doing wrong?
Hi there
For some reason I can't get any servos (BLToucha and a cutting servo) running on the new beta firmware. It works just finde on the last RRF2. I get no error message, it is just not executed. Please tell me if you have any idea why executing M280 is not working. Here you find my config.g:
; above are only drive and endstop settings...
; Z-Probe (BLTouch)
M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin
M950 S0 C"exp.heater3" ; create servo/gpio 0 on heater 3 pin on expansion connector
M280 P0 S10 ; send control signal to BLTouch through servo/gpio 0
; Heaters
M308 S1 P"spi.cs1" Y"thermocouple-max31856" K"K"; define H2 temperature sensor
M950 H1 C"e1heat" T1; define H1 heater for Tool 0
; Cutting Servo
M950 S4 C"exp.heater4"
; Tools
M563 P0 S"Printing Nozzle" D0 H1 ; Define tool 0
M563 P1 S"Touch Probe" ; Define tool 1
; Define offset between Tool 0 and 1

G10 P0 R0 S0
; Small last settings
M302 P1 ; Enable Cold Extrusion
G92 Z0 ; Set Z to 0
; Automatic saving after power loss is not enabled
Hi there!
Is therre any way to print custom messages from somewhere in the firmware either to USB or to the console? I can't find out how and I would like to debug my code (currently trying a new kinematics..).
I am looking forward to your answer

Alright solved it. Was using the wrong build of RepRapFirmware..
Unfortunately now I have a different problem (Sorry that I ask these 'beginner questions'.. I'm new to this project..):
I can complie all packages except the RepRapFirmware. I always get these errors and the build fails:
Thanks! I had the wrong version of CoreNG..
Hi there! Can anyone help me? I am trying to build the Firmware for DUET Ethernet but I cannot build RRFLibraries (Mac). All other packages work (except RepRapFirmware of course..) The following errors occurs every time:
Looking forward to your answers
