Heater Error message, don't know what's wrong!

Recommended Posts

Hi all. I've been getting the Heater Error message on my UM2 lately. I had installed the Olsson block a couple of months ago, and I've had no problems whatsoever up until last week, when I got the Heater Error for the first time. I noticed that the temp sensor was loose inside the block (I pulled it from the back and it came right off), so I tightened the screw on the block and I thought my problem was solved. But the next day, after about an hour into the print, I got the dreaded Heater Error message again. This time the sensor was firmly fixed inside the block. I've been using izzy's shroud (https://www.youmagine.com/designs/um2-fan-duct-v2) and the stock 25W heater. I'm printing with PLA at 210C and using Cura 15.04.4.

Yeah but it can be print design dependant. A area where the fans airflow is deflected towards the nozzle long enough to cause the error.

I had the same issue where it happened a few weeks after changing my fan shroud.

Could be that the temp sensor is not sitting in a slightly different spot then before maybe. Or have you upgraded firmware recently?

Thanks again @Labern. I started using the fans at 70% and it looks to be working fine so far (I will, of course, install the 35W heater as soon as it arrives).

I don't think this is related to the aforementioned problem, but I also started noticing that my first layer looks like this (it looks like it's transparent on a specific portion of the bed):

This is only on the first layer, all the other ones look ok:

Any ideas?
