Has anyone ever used these heater cartridges ? Here's what they say on the website: Cartridge heaters are the industrial way to heat up your hot end. They will heat it up faster, more consistently and look a lot nicer in the process than power resistors. They are insulated with magnesium oxide and encased in aType 304 stainless steel sheath that is 5mm in diameter. 12v Power Required Maximum Temperature of 600° C. Here is the link, I noticed they sell them on eBay as well. I just wanted to know if anyone's used them or if they work better. Also has anyone bought extruders from qu-bd.com I also would like to know if they are a reliable company with good products. Thanks.

About 10 mm overall are exposed, so a lot of energy is wasted.
But other than that, I am quite happy with a heater cartridge as it also has the added benefit of not needing solder joints and heat shrink tubes subjected to high temperatures (yeah, saw a solder joint break on a resistor).]]> uGen General Sat, 30 Mar 2013 15:22:28 -0400 https://reprap.org/forum/read.php?1,195933,196185#msg-196185 https://reprap.org/forum/read.php?1,195933,196185#msg-196185 REPRAP SQUAD General Sat, 30 Mar 2013 12:04:39 -0400 https://reprap.org/forum/read.php?1,195933,196181#msg-196181 https://reprap.org/forum/read.php?1,195933,196181#msg-196181 i got some 20x20mm aluminium square bar and drilled an 8mm hole off centre to one side.
drilled and tapped 2x 4mm holes into the block which i attached to my aluminium bed with 2x countersunk screws.

it works like a dream.
Im using painters Blue tape on the surface of the bed.

just need to stop my x axis going off on a tangent now and i will be up there with the elite.]]> JT General Sat, 30 Mar 2013 11:40:25 -0400 https://reprap.org/forum/read.php?1,195933,196131#msg-196131 https://reprap.org/forum/read.php?1,195933,196131#msg-196131 -------------------------------------------------------

Ahh...good..also just realised I had 50W not 40W in my mind...don't ask me why..one of those days :)

May have to get one and try it out.

Thanks

Classic resistors are 6.8 Ohms so give just below 2 amps. And with less wattage, they have a higher duty, because the heat to furnish to the head is the same.

In any case that works flawlessly here. The circuitery may limit current to what it can furnish.

As I said before, there is a 30W version available too.]]> alj_rprp General Sat, 30 Mar 2013 08:15:07 -0400 https://reprap.org/forum/read.php?1,195933,196117#msg-196117 https://reprap.org/forum/read.php?1,195933,196117#msg-196117 Or am I missing something?]]> IceMan General Sat, 30 Mar 2013 07:25:28 -0400 https://reprap.org/forum/read.php?1,195933,196057#msg-196057 https://reprap.org/forum/read.php?1,195933,196057#msg-196057 www.ebay.com]]]> aduy General Sat, 30 Mar 2013 03:46:23 -0400 https://reprap.org/forum/read.php?1,195933,196039#msg-196039 https://reprap.org/forum/read.php?1,195933,196039#msg-196039 REPRAP SQUAD General Fri, 29 Mar 2013 23:28:45 -0400 https://reprap.org/forum/read.php?1,195933,196037#msg-196037 https://reprap.org/forum/read.php?1,195933,196037#msg-196037 aduy General Fri, 29 Mar 2013 23:23:30 -0400 https://reprap.org/forum/read.php?1,195933,196008#msg-196008 https://reprap.org/forum/read.php?1,195933,196008#msg-196008 Werner]]> BerryBot3D General Fri, 29 Mar 2013 20:35:40 -0400 https://reprap.org/forum/read.php?1,195933,195981#msg-195981 https://reprap.org/forum/read.php?1,195933,195981#msg-195981 aduy General Fri, 29 Mar 2013 18:09:12 -0400 https://reprap.org/forum/read.php?1,195933,195970#msg-195970 https://reprap.org/forum/read.php?1,195933,195970#msg-195970
the cartridge fit in the resistor hole, it is just a bit longer.
My J-head has a grub screw to fix it. I used fire cement to insure that there is good thermal conductivity both on cartridge and thermistor.]]> alj_rprp General Fri, 29 Mar 2013 17:32:10 -0400 https://reprap.org/forum/read.php?1,195933,195952#msg-195952 https://reprap.org/forum/read.php?1,195933,195952#msg-195952 REPRAP SQUAD General Fri, 29 Mar 2013 15:33:12 -0400 https://reprap.org/forum/read.php?1,195933,195951#msg-195951 https://reprap.org/forum/read.php?1,195933,195951#msg-195951 REPRAP SQUAD General Fri, 29 Mar 2013 15:31:44 -0400 https://reprap.org/forum/read.php?1,195933,195948#msg-195948 https://reprap.org/forum/read.php?1,195933,195948#msg-195948 In bang-bang mode, it heats so quickly that it would overshoot by 12°C or more. In PID mode, pronterface reports regulation to be less than 1°C so it is perfect. came with very nice wires long enough to go directly to the ramps

A 12V 30W version is sold by some german vendors so would heat a little slower.

here is mine. lot cheaper too :

I'm currently leaning toward using the resistor because that seems more common/known and reduces the amount of current running through my little Sanguinololu board (which has been a concern of mine after looking at those little traces).

I'll be interested in what you find out.]]> cobrageek General Fri, 29 Mar 2013 13:36:31 -0400 https://reprap.org/forum/read.php?1,195933,195933#msg-195933 https://reprap.org/forum/read.php?1,195933,195933#msg-195933
