Re: Believe heater band has failed, specs please

If I remember correctly, you're using a beta version, correct?

You ran it on 110VAC, correct? If not, that could lead to early failure.

At any rate, a 50 watt heating band is appropriate. Do not exceed 100 watts.

Thanks Tim,

Yip beta, im uk spec power so its 240v rather than 110v

Do you have internal diameter, think its 30mm

Page 4 of the instructions wrote:

Power: 110VAC, 175watts peak, 50 watts average

You're very lucky all that happened was the heater going open circuit! You were pumping 4x the rated power through it!

Diameter is 1.06". 30mm should be fine, 25mm would be better.

My bad, assumed with you sending a uk plug for the dc power block that it would have been a 240v heater band.

One now on order so normal guernsey delay should see it about the 10th, this one is 240v so should go a bit longer smile

Re: Believe heater band has failed, specs please

It appears my heater band has quit working. Ive tested other heating elements and the Sestos PID controller is indeed working. I keep looking for heating bands / heat bands / injection mold bands but only find 110v, 120v, 230v but none for 12V. Not happy that it has already failed with about 5 to 6 lbs of pellets through it, and barely 2 months old. Any ideas where I can find this heater? I prefer to use the band heater as I do not want to bastardize a pipe coupler and use reprap style extruder heaters.

Like was posted in the other thread, please get in touch via the Filastruder contact page. Out of 2700 heaters out in the wild there has been only one reported failure, so I'd like to learn more about what happened. I'd be happy to provide a replacement via exchange.

The beta Filastruders used a completely different type of heater band. Could we please not bump 2 year old threads, in order to avoid confusion for other people who may not check the post date?

Re: Believe heater band has failed, specs please

Sorry for bumping an old thread. I don't do forums much, another reason why I usually buy from a company that has PHONE support. Email and forum is very time consuming and waiting to get replies is a pain.

I don't understand your attitude though. Everything is a COMPARISON. Ever think that maybe that 1% failure can happen? Or maybe QC didn't check and a few slipped through? Your not the only dedicated buyer of those 12v heaters, I'm sure they supply companies everywhere, so there could have been a bad batch and I unfortunately got one. No where did I mention I was pissed t filastruder, I mentioned I wasn't happy that it lasted that short of time.

I also didn't realize it was such a hassle for you to tell me to send a mail through filastruder contact page, when you could have just told me here. Makes no sense to have to send the same information 2x. Why should I have to pay shipping back to you when I can just order one and get a few extras incase? I have no problems sending in the bad/defective one, but if I am gonna get one I might as well get 2 or 3.

I generally reply to emails within an hour. Same goes for forum posts, I replied to yours in under an hour, on a weekend.

There is no attitude, I simply stated that such a failure is exceedingly rare and I'd like to have a look at the actual heater to diagnose what went wrong. 1/2700 is not 1% failure rate, it is 0.03% failure rate.

Actually these heaters are custom made, by a company here in North America that produces them to my specifications in accordance with UL/CSA certifications. They are not an off the shelf part.

I asked you to get in touch via email because doing an exchange will require personal details such as your address, which should not be shared publicly.

You don't need to pay to send anything back, doing an exchange means I'd cover shipping both ways. Before doing that, you'll need to test the resistance of the heater at the high temperature heater wires in order to rule out any bad connections.
