I wouldn't say that. I purchased two of the new hot ends (without knowing that they were a new design), and both of them failed. Solidoodle sent me replacements immediately, and the new ones had some minor design changes that appear to have solved the problems I originally had. I would not hesitate to purchase a Solidoodle based on that one issue. Solidoodle are always in the process of trying to improve their product.
Living on the other side of the world where postage is not an overnight deal, I don't think that it's acceptable to beta test new designs on your paying customer base, rather sort it out in house before hand. I also wasn't given the immediate replacement option, rather I have to ship it back and wait for them post the replacement. If I had known before hand that it was an issue, I'm not sure I'd have bought one, at least not yet or maybe would have bought additional hot ends. May I ask how yours failed and why you think that a 100% failure rate on the 2 extras you bought is OK? My idea of improvements are extra features, not correcting design flaws based on customer feed back - I believe that's the definition of beta testing. Please feel free to correct me if I'm wrong.
There was a small run of defective hot-ends. We fixed the problem.
Now, we do test everything in house. One thing that is hard to test in our situation is "long term" failure.
I.e something that will fail in a month or so. That might not pop up in our radar until it's too late.

We've heard of issues like this on Mac. Does your printer print at least?
Ya it prints. I wanted to be able to change the extrusion rate via EEPROM instead of firmware though.

Thanks for the honest response, even though you've had some difficulties with your own unit. A proven track record of good customer service weighs heavily in the decision of who I purchase my first 3D printer from, so it is great to hear that the Solidoodle support staff are willing to work with customers to resolve issues, even if they are a bit overwhelmed at times due to the popularity of their products.

]]>My solidoodle 2 arrived with the new heat core... Lasted 2 weeks, and the resistor burnt out. I also had problems with the temp fluctuating +-10 degrees C. Ordered these replacements which will hopefully work ok:
ebay: "(3) 6.8 Ohm 3 Watt Power Resistor, Hot End Heating Element DIY 3D Printer Parts"and a few of these:
bilbycnc "Heat Resistor 6.8 Ohm"
My other options are paying more for the postage than the hot end is worth or wait 5-7 weeks. Sigh..
Is the new hot end design prone to failure, and standard on all new Solidoodle 2 printers? If so, that's a damn shame. I've been doing lots of research on sub-$800 3D printers and am about to pull the trigger on the SD2, but I don't want to spend nearly $700 on something that has these types of design flaws.

I guess not!
The following picture shows how the new hot end is constructed. A block of aluminum with a hole drilled through it and a resistor stuffed in the hole. The resistor does not fit snugly in the hole, nor is thermal compound present (probably would just melt and drip out anyway).
My first attempt at soldering things failed. I'm in the process of trying again.
You cannot solder this heat end. Solidoodle has a new design. There are teflon wires attched to resistor. This will prevent connector from burning out. Check out the solidoodle store. This design works perfect. The problem with your Heat end is that the resistor is not insulated in the connector. Also, if you try to solder your own connections... solder will melt out. Even if you use lead free solder.. it will still ooze due to the constant high temp. Try to get the new heat end. IT WORKS 100%
