heater cartridge died after 6 months

[TheRealJoost 5]

Like the title says, my heater cartridge died in my UM2+, about 6 months old. My Ohm meter reads 130k, so it is definitely done. Perhaps 250hours total printing done with it. Seems a little soon for a repair, no? Should I count on having a few in stock?

Not knowing how warrantee and that sort of thing works out in the USA, I decided to purchase a replacement cartridge (57 bucks) and do the repair myself.

btw, the cartridge and PT sensor just slid out ever so easily, no friction whatsoever. How do these things normally stay in place?

Mine has about 6K hours on it and still running. (Knock on wood)

Those items are not covered under warranty so you were good to buy them.

Hi,

The middle screw hold both, the heater element and the PT100B thermistor.

Be careful and not rebend the wire when removing the PT100B, if needed.

Just buy one heater as a spare, this is the one that's work the hardest. But they also can last "almost" forever..

PS. Robotdigg sell each of them for 6 USD.. But takes a little bit longer to get.

The heater should last a lot longer than this.

Thanks.

@Torgeir; I did have a look at Robotdigg but they don't list the UM2+ cartridge (35Watt), only the UM2 (25Watt).

Hi,

Yes, forgot that you're using the 35 W version. Well, I'm using the OB and 25W heater element and no problem at all. But I'll guess it will depend of what kind of material to be used etc.

Good Luck.

Torgeir.

In USA you can get UM2 heaters at 25W, 35W, 40W, 50W in my store. And much cheaper than $57. Wow - I didn't realize how expensive some people sell them for. thegr5store.com.

Bummer, I wish I knew, care to share your store's web link?

Um. Are you kidding? You know that when something ends with ".com" it's probably a web link right?

(grin) yep, I do understand the .com thing. My browser didn't show that .com nor did it look like a clickable link when hovering over so my bad I missed that.

On another note; I installed my new heater and noticed that the temperature stays _a lot more_ constant. With the old heater element I had a swing of about 4-5 deg C around the set point. With the new it is pretty much spot on. (Using Simplify3D to monitor the temps). I wonder if that swing was a sign of failure or if it meant it wasn't screwed down well enough so it could not dissipate its heat properly and failed as a result.

The good thing is I am printing again, yay!
