@jay_s_uk I powered down as you suggested, changed the plug to pin Fan0 and now it all works ! i have a controllable part fan thanks so much for your help, it was driving me crazy ! turns out i was changing things with power on.

@jay_s_uk ok lol ill wait till its finished, but that will be tommrow. Ive tried it before but never has it run whilst printing

@jay_s_uk i have a print running right now, if i swap to pin Fan0 will that create any problems whilst its printing?

@jay_s_uk i can change the plug easy, ill swith to fan0 and i have to change S0 to S1?

@jay_s_uk ok so ive got the fan plugged into the wrong pin, its in Fan 1 , so i need to change to pin fan0?

@jay_s_uk is fan 0 the part fan? i thought that was fan 1?

@jay_s_uk i tested the fan this morning while everything was cold at around 15c. plugged the fan into Fan1 pin and it was off, and then heated the nozzle, the fan came on at 45c and stopped when i stopped heating and temp dropped below 45c.
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on

I gather that T45 starts the fan at 45c and one of the other parameters P1 S1 or H1 controls the speed of the fan?

@jay_s_uk thats the issue i have on pin Fan1 its always on, never goes off, i cant switch it off and its at 100% speed. On pin Fan0 and Fan2 it wont turn on at all. I've put in fan speed into my slicer and even switched on fan whilst printing to no avail. i'm using a blower type fan which i used before on a Rumba board, but since changing to Duet i cant get it running correctly.
Ill double check once these current prints stop that the fan is always on regardless of print activity.

@jay_s_uk

Thats the M563 command

M563 P0 D0 H1 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C

Hello everyone, New to the world of Duet2 Wifi boards and have been tinkering with my own design printers using the Duet2 Wifi board. my issue is i cant get the part fan to work as a variable speed fan controlled by the web interface. i have tried the PWM fan pins Fan0 Fan1 and Fan2 with no success, although when plugged into Fan1 the fan runs continuous and at full speed regardless of when print is started or running. My config file for fans looks like this:
; Fans
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 fan1 and set its frequency
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on

Is there something ive done wrong here? I kinda really need to get my part fan running as i'm printing with LDPE in a pellet extruder and need the part cooled as i print. Any help would be greatly appreciated.

Thats gotta be it ! i never realized the slicer was sending a command to heat the bed. The printer i have been using must have the heated bed disabled in config as its a mains supply heated bed. I have a print running and in about an hour i will delete the heated bed command and see if that fixes the problem ! thanks so much for the help !

One thing that frustrates me is the homing of Z is really slow its showing as 2mm/sec how can i increase that speed? The initial raising of the bed is at 2mm/sec but after the probe has been activated the movement is much faster. It moves down then moves up to meet the nozzle faster than the initial z axis movement up. i looked in the config files M558 which shows

M558 P9 C"^zprobe.in" H5 F100 T2000 ; set Z probe type to bltouch and the dive height + speeds

Is the H5 the speed setting for the initial probing?

Thanks in advance

so delete the M140 command?

@Phaedrux I have tried changing the T0 around and no difference really. I keep getting a M140 error which is the heated bed which i don't have connected. I would start a print and ill get these errors which i close and resume print as its been paused automatically due to a heater fault. if i start the print it will run for 600 seconds and stop. the strange thing is once that occurs as long as i dont switch off the printer or reboot the board i can send a file to print and it does without a problem. Maybe i need to disable the heated bed?

@Phaedrux Thanks so much mate, ill try it out

@Phaedrux In my config file?

@Phaedrux this is the last code:
; layer end
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G91;
G1 Z50;
G92;
M84 ; disable motors

@Phaedrux i assume you only need the start file?
G90
M82
M106 S0
M140 S110
M190 S110
M104 S285 T0
M109 S285 T0

@Phaedrux its a huge file to cut and paste?

@Phaedrux i'm not sure how to do that?

@Phaedrux uploading the file through web interface.
The heater can be set manually and work fine and i have PID tuned them. I upload a gcode file then click start print and i get this error message,
Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

the printer will continue trying to print without heating the extruder so i just stop it. if i heat the hotend first then start a print it will print as i'm manually overriding the temp settings.
i think?
