what I find most annoying is that, the solidoodle compares well to most rep raps because, well by and large it's exactly the same as most repraps.
simple cartesian machine, open source extruders, open source nozzles, open source circuit boards, open source heaters. running with open source software...
yet even though they've borrowed most of the design from the open source hardware community, (and there is nothing wrong with that), it's a little galling when you ask, what's the resistor part used in the hotend, and they can't/won't say. pretending it's company secret IP, but if you go to the reprap pages then you can narrow it down to a couple of choices. the only secret is which design was pulled down and chosen as the one that they were going to copy!
The solidoodle people perhaps need to start remembering that a lot of designs that they are using at the moment are released under GPL. meaning, if they are using as is, then no they don't need to release source files, (in which case there is no company secret at all! -just let us know what design so we can fix out machines!!) if they have changed the design, using different components then it is an obligation under the terms of the license that they release source designs. -in which case, it's not really an ask nicely what design did you copy so I can know what replacement parts to use, it's a case that you must tell me.
1) No Included Software - Multiple open source software that the user has to download isn't acceptable for a mass-market product. Instead, a set of software packages need to be bundled together and wrapped with a decent polished UI (one interface, no multiple windows) and installer and delivered on a single dvd included with the printer. The existing external packages should still be available for people who want them, but the average consumer doesn't want to have to assemble them.
I've never felt the need to throw my computer out of the window, despite the fact that it didn't come with any office software and I had to make a choice between multiple open source office type applications, or several commercial applications.
2) Un-Smart software - The software needs to be smart enough to recognize printability problems with objects and recommend solutions. For instance, if the base layer is too small relative to the object height, it should recommend or automatically add a raft or brim.
I agree with you on this, it seems like it should be easy to implement as well.
3) Clogs - They're too easy to get and the consequences too severe. The printer should ship with a warning label on the extruder that says "WARNING - Do no leave print head heated above 80 degrees C when idle for more than 10 minutes." If possible, the firmware should automatically prevent this from happening. To make the consequences less severe, the nozzle needs to be easily removable (ala mk4) and an extra nozzle needs to be included. Not only does this keep the printer from being immediately incapacitated with a single clog, it sets reasonable user expectations and turns nozzles into a consumable item.
this would be more practical with a more powerful heater, so one that could come up to temperature in seconds, but whilst people are going to need to wait a couple of minutes for the hot end to heat, they are going to think, I'll just be a second to quickly change this...also, yes, I wish that there were spare nozzles too, considering how cheap they are! I wish they'd just stick one in as a part of the pack.
4) Leveling necessary but too hard. Thumbscrews should come installed beneath the bed leveling screws and the z-stop adjustment needs to be made more accessible, potentially by a knob whose edge extends through a slot in the frame. A built-in depth gauge would be nice, but at the very least, the software could have a built-in bed calibration procedure, perhaps by printing predefined circles at different locations on the bed. In fact, simple calibration cubes and starter objects should be included as well.
and have the added advantage of not having to poke holes in the kapton square.
5) Curling - Some sort of insulated case needs to come standard, even if it's made mostly of cardboard or MDF.
to be fair they do offer a case, but it's billed as some kind of non-essential optional extra. it'd be better if it's virtues were more extolled.
6) Printed manual - A $500 printer needs to come with a well-written printed manual, even if it's culled from wiki articles and just manufactured in limited runs or printed on the fly using lulu or cafePress. Making customers search online is unbecoming for a product in this price range.
I disagree here, the trouble is that most documentation for reprap style machines is written by rep-rappers themselves, not necessarily a bad thing, but there are a whole load of people with a load of different writing styles, for some of whom English is not their first language, any manual compiled like this would be disjointed to say the least.
if there was going to be a printed manual the then they should just do it properly, write it properly, in house not try to rely on the world to support a commercial product for them. though it's still great that this forum is a better resource than the official FAQ or the google group. but it also feels a bit like... why can't they get it together a bit more!
which kind of leads back to the tech support...
I'm kind of tired of hearing about how people get no response, or how people get told that they can't be told what the part numbers are as they are trade secrets...
first you must pay to ship a part back and then we'll pay to ship a part to you...
as I say, at the end of the day I just think get it together a bit more...
I don't really think it's the product that's lacking... the only part of the experience that's being a real let down is all the stories that we keep hearing about the company!
