Done, I know its taken a while, https://www.thingiverse.com/thing:2388496 including a link to a youtube video.

If you are using this combination, do you just essentially have G30 in your Home Z

or

Do you need to turn of mesh bed levelling with a G29 S2 then run a G30 probe to set Home Z and then turn the Mesh bed levelling back on with G29 S1

Thanks to everyone for their comments, so, and let me take a moment to reflect here, but yes, you are all accusing me of being a cheapskate

I can't use Noctua as they don't do 24V 40mm axial or 40mm
blower and Sunon don't do any small blowers.

Any other suggestions?

Here's the one I have at the moment

dc42: you say 500Hz may be a bit fast. what would be the standard setting?

Thanks

Hi, I appear to be getting through fans, both hotend and part on a regular basis. They seem to present the same fault, at first they run absolutely fine, but after a few months then they don't start up on their own, but if you manual flick the blades then they start spinning properly. after a while though they just wig out completely.

Now I may just be buying bad fans, but I have experienced this phenomena 4 times in four months with both axial and radial fans. Everything runs at 24V. Do I have the correct settings?

; Fans
M106 P0 S1 I0 F500 H1 T45 ; Set fan 0 value, Extruder 1 Fan. PWM signal inversion and frequency. Thermostatic control is turned on
M106 P1 S0 I0 F500 H-1 ; Set fan 1 value, Extruder 1 Part Fan. PWM signal inversion and frequency. Thermostatic control is turned off
M106 P3 S1 I0 F500 H2 T45 ; Set fan 1 value, Extruder 2 Fan. PWM signal inversion and frequency. Thermostatic control is turned on
M106 P7 S0 I0 F500 H-1 ; Set fan 2 value, Extruder 2 Part Fan.PWM signal inversion and frequency. Thermostatic control is turned off

Thanks for your help, have now applied full resettable fuse and 10K resistor fix. Funny though as could not find original fault.

Whilst fixing I have also recognised a further issue but as is unrelated I have created a new thread.

Its a V1.01 board and that measurement is 60KOhm so guess the fuse has blown

Everything has been working fine for a long time, I was printing fine yesterday, but after the print had ended this fault just presented itself. I have obviously tried switching the unit on and off multiple times, but it always comes up with the error. I know the FW is old, but since its been working fine, I don't think its related

I have, its linked in the message under the picture.

Hi, My DuetWifi is showing a permanent fault on heater 1 as per the attached PNG. I have measured the resistance of the heater 1 thermistor and it reads 159kOhm. Just in case, also checked the heater 2 thermistor which is showing 157KOhm and the Bed which is showing 158KOhm
The above measurements were taken at the board end of the cables.

I have attached diagnostic and setup files.

Hi dc, as you can see from the bed.g I run the leadscrew correction 3 times, and yes it goes down each time, for instance I get readings such as
first correction difference 0.3
second correction difference 0.08
third correction 0.02

but the issue arises if I run the bed.g as above, then I run it immediately again, then I am back to having say a 0.3 difference on the first shot.

I don't know why that is occurring as I would expect a 0.02 difference or below.

Hi I think I am having trouble with my Idex bed file. I have an Idex with separate Z motors, one on each end of the X U axis.

Therefore I have a bed.g file that firstly tries to balance the z motors then does a bed compensation.
The reason I say I might have an issue is that if I rerun the bed compensation staright after running the bed compensation then the z alignment is up to .2mm out so the z motors realign themselves again. the bed.g file is below, comments really welcome.
