No Homeing after fw update to 3.2

fragle

Hello,

i ve updated my duet2 wifi to 3.2 and i am struggling with the home funktion on my delta.
i i say home all axes, i am getting an G28 Failed to enable endstops.

Thermistors an already working, display too.

homedelta.g

G91 ; relative positioning

G1 H1 X470 Y470 Z470 F1800 ; move all towers to the high end stopping at the endstops (first pass)
;G1 X-5 Y-5 Z-5 F1800 S2 ; go down a few mm
G1 H1 X10 Y10 Z10 F360 ; move all towers up once more (second pass)
;G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
;G1 X0 Y0 F6000 ; move X+Y to the centre

Maybe someone have an idea ?

best regards

post the config.g (section with your endstops at least)?

i assume you are comming from a version 2 firmware

please read

found it

But now i am stuck with the print cooling fan

i the old config.g i use for the print cooling fan /Heatsink

M106 P0 S0 I0 F100 H-1 C"Print Cooling"
M106 P1 S1 I0 F100 H1 T45 C"Heatsink"

if i understand the new system correct, for V3 it should be

M950 F0 C"Print Cooling" 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"Heatsink" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1 T45

But no print cooling fan and the heatsink fan is running permanent

@fragle said in No Homeing after fw update to 3.2:

M950 F0 C"Print Cooling" 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"Heatsink" Q500 ; create fan 1 on pin fan1 and set its frequency

those are not valid pin names

fan0-fan2 are the pin names

i switched back to 2.05, i do not get warm with the new System. On my others printer there is klipper and reptier running, which i can understand, but reprap is too high for me

just use the configurator to generate a rrf3 config

https://configtool.reprapfirmware.org/Start

put in the relevant details and it should not be that hard.
