Silent hot end switch up?

Silent hot end switch up?

Postby AmazingSpanoMan » 2014-Jun-Mon-21-Jun

So I love my red limited edition metal simple so much I decided to grab a white metal kit. I finally got around to building it, literally took an hour to put together. One thing I noticed when adjusting the height on the probe was that the hotend is different from the one I got on my Red. The wires going to it aren't as thick and the metal on the bottom is the same size as the barrel compared to the older one that is bigger on the bottom.

Was there a silent swap out? Does anyone know if this smaller one has any benefits over the bigger?

One (bigger) uses a heater cartridge and an aluminum heat block, the slimmer one uses a heating wire wound around the barrel and a ceramic cement covering. IMHO the bigger one is better as if the heater fails it can be swapped out with a new cartridge, the slim one is a write off if the heater fails unless you are willing to try constructing your own. IMHO the aluminium heater block based one has a better thermistor mounting method, which is easy to replace.

Its the reason why i decided not to buy my replacement hotends from printrbot, as they announced that they would send either for any order, and you don't get the choice, so its a crap shoot. I dont want the ceramic cement coil ones, i want heater cartridge based ones. Instead i ordered two anubis hotends from QUBD, as I know they are heater cartridge based.

What about those 3DP hotends? You think one of those would work well with the metal setup?

It would seem Printrbot chooses these hot ends at random. My original hotend was a nichrome wire heating element. It failed just outside of warrenty. Their replacement program although enticing, isn't really economical enough since You have to ship your part to them, wait, they ship back, etc. Lots of down time. Only a 19$ difference, so I ordered a new hot end and I'm hoping it is a cartridge style. In the mean time I ordered 30ft of nichrome wire off ebay for 6$ and will at least attempt to repair the original.

RRS,

I ordered a qubd one-up in Feb, I would love to give you feedback, but here we are in June. Still no printer....Promised delivery in april...then May. Maybe their delivery on individual parts is a little more expedient...But for the time being, given how upset most people seem to be about their orders not being filled (some people have been waiting close to a year). Perhaps a more reputable supplier would be best. Your printer looks like an awesome machine. Can`t wait to see it print something!
