Fan shroud (Labern) Heater Error on first layer (no fan)

[markusmaker 2]

I printed the labern fan shroud for olsson block https://www.youmagine.com/designs/um2-dual-fan-shroud (also got I2K)  and taped it with kapton.

Mounted it (2 spacers used on right side of heat block):

On the first layer I got a heater error (with fans off):

I printed colorfabb XT white at 235C.

Anyone can tell me where I did go wrong?

Thanks!

Which firmware version do you have (you can check using the menu system on the printer).

heater error (as opposed to error stopped - temp sensor)

You get an error if the heater can't move a certain amount in a certain time while driving full power (when it is close to goal temp it typically runs well below full power):

Firmware

Version

14.09 - does not have the feature

14.12 oct 16, 2014 - feature introduced. 20C in 20 Seconds

15.01 jan 14, 2015 - from 20 secs to 30 secs (now 10C in 30 seconds)

Hi gr5,

I am using TinkerGnome-MarlinUltimaker2extended-15.10.2.hex at the moment.

Switching back to the standard fan shroud everything works fine.

Kind regards,

Sorry to hear your experiencing problems.

So you are getting the errors even when the fans are not working? Strange.

Did you put the spacers as per grey ones in this photo?

Are you using the original nozzle?

Hi Labern,

yes it happend on the first layer, fans were at 0%. I use a M4 screw nut as a spacer. The screws come out at about 1mm on the other side. I use the Olsson block with a 0.4 nozzle.

You might want to either disable the "heater error" check or alternatively get a 35W heater. The 25W heater that comes with the UM has quite a bit of variation from printer to printer and may actually be as low as 20W.

I go with gr5, when I did the conversion I went with the upgraded heater and have had no problems with Labern shroud but I do introduce the fans gradually I do this as to not shock the Olson block and cause a sudden drop in temp.. I also made 4 spacer about 3mm thick under all 4 thumb screws. I also got a new Bowden tube as I'd cut the old one to use as spacer in iRoberts feeder design.

I ordered a 35W heater, when the printer is back from iGo3D (z-axis problem you know :-) then I will change the heater.
