    • Home Z with IR probe with Mesh Bed levelling

      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

    • RE: Strange failure rate of fans

      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
      0_1558076099453_fan.jpg

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

      Thanks

    • Strange failure rate of fans

      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?

    • RE: Heater Fault

      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.

    • RE: Heater Fault

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

    • RE: Heater Fault

      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

    • Heater Fault

      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.

    • RE: Idex Bed.g

      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.

    • Idex Bed.g

      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.
