My SD3 is still pending, so I have no experience with the printer, but I will shortly. I used to operate a Komo CNC machine a number of years ago, so I do have some experience running a complex CNC system.
I do, however, have experience with this forum, and I put in a lot research time before buying my SD3. The reason I went with Solidoodle was, primarily, the hundreds of users contributing their comments for fixes, hacks, improvements, techniques, etc. A big hats off to the amazing super users in this community! I also went with Solidoodle because they use Repetier and other open source software and electronics, which go through their own improvements on a weekly if not daily basis. It now makes me really happy to see that Solidoodle is firmly standing alongside their "online" community, looking for ways to better connect, and improve. Furthermore, Solidoodle is rolling out an all new aluminum z-carriage and new extruder design. These are substantial product improvements, done in a relatively short amount of time, and this gives me a lot more confidence about this company.
I truly believe that no matter which printer you buy, you're going to go through an awful lot of trial, error, frustration, and learning. Every company I researched suffers the same maladies. At least with Solidoodle we have resources. We can download and reprint nearly every bracket on our machines, and make them shiny and blue - for about 20 bucks in materials. We can go to ten websites and get new motors, and controllers, and hot ends, etc - for cheap. Even after adding enclosures, and glass beds, and filament spool holders we're still in the money. What makes this all possible is the Solidoodle community - guiding us, reprinting a part for us if our printer is down, warning us when we're doing something less than advisable, suggesting cool modifications, etc.
I shutter to think that with so many higher end printers the only resource I would have would be myself and the company. Crash your hot end and ruin three brackets? No problem, just pay the company a lot of money or get out your calipers and prepare to spend 8 hours designing a new one, and hope to heck you can find somebody to make you one. These types of scenarios go on and on.
In my opinion, the only 3d printer companies that will still be around 5 years from now will be the ones that are amenable to outside development, more or less open source, have strong online communities, and stay in contact with their communities. For my printer to fail would mean that we in the community would all have to fail.
My positive changes for support is this: keep asking us, your customers, for help - like you're doing. This is awesome customer service. Second, get your own version of Thingiverse for downloads and sharing, and start with a category for printable improvements to your own printers. Finally, why not put more emphasis on your blog, and begin with more timely updates. For example, why not include the following topics: "modification of the day" or "printing tip of the day" or "top 5 most asked questions this week" or "best user mod of the month" or "factory tip of the day", etc. To build excitement, it might be helpful to run a contest every now and then for user submitted modifications or tips. Good luck!
