I'm still a big fan of the connectors I'm using. They can't be connected backwards and they're simple, small, decent current, pcb mountable, reprappable and moderately cheap to buy.

Yeah, and I don't think google maps represents the tree hierarchy either. The nice thing about a hierarchy is that it can represent a fallback regional distributor where there isn't a country or city distributor.by sai - General

This seems like a nice idea. It's a shame it's an offline file format. To represent this, all we really need is a tree, not a more general graph. Surely there must be something we can use for this that's a bit more onliney and that multiple people can edit?by sai - General
Yes, I've aimed for high thermal mass in my machine. I'm curious to know why low thermal mass would be a good thing too. The high thermal mass smooths out the effects of starting and stopping the extrusion, which suddenly sucks energy away from the system. I specifically add mass to my extruder just to maintain a steady temperature.by sai - Reprappers

It's always been my understanding that there would be PIC firmware binaries available directly for download. Obviously there needs to be a build process somewhere which is why there is one, but not everybody needs to run it.

It would definitely be a cool thing to make one day. I believe the main reason for not using them (which you already suggested) is that it has some stability issues. Making it as precise and stable with a tool on it is much more difficult than something that is supported on both ends. But, guaranteed, somebody will make one...by sai - General
I basically agree too... and his structure sounds pretty reasonable too. Though if Development was opened, I think we could ditch Contributors entirely. But as you say, I also think it's premature by a few months. Based on other earlier discussions and decisions, I think it should coincide with release 1.0.

Some PC power supplies (particularly older ones you're likely to scavenge) have a power switch on them. It's not quite the big red button kill switch, of course... That would look much fancier. The software has an option to pause after each layer or after each segment, and can be turned on at any point during production. So that gives you a way of pausing if you want to, although it's a few mby sai - General
Within reason, the specific resistance and beta values aren't too important. The more difficult thing to find is a thermistor that is rated to go up to a decent temperature without breaking down or having its leads fall off. You probably also want one with some kind of thermal conductor to transfer the heat to the sensor efficiently. For example, some thermistors have a metal tab that you canby sai - General

My Repstrap uses an MDF work surface. It's pretty durable, has reasonable adhesion (but not too much) and is cheap. I haven't printed much on my machine yet, but what I have done was with CAPA and it's been great as a surface for that.by sai - General
Yeah, probably not a bad move. Compared to the time to build the JDM programmer, the cost isn't really that high anyway.by sai - General
Yeah, I always build everything on a breadboard to start with. It's a good way to start, but I find once you start using a breadboarded device too much like a real part, you end up getting loose connections or shorts that you don't normally get under prototyping conditions. They're sometimes a pain to track down and could potentially damage other components, so I always like to make a proper boby sai - General
I have a bunch of Intel boards, and I've never run into that problem. Perhaps there's just something wrong with your JDM programmer (?). I don't know about Dell because I avoid that stuff like the plague, but I would have thought they'd be using the same sort of serial chipsets as all the other major vendors.by sai - General
Yes, I'm one of those that have had a very different experience I've been using a JDM programmer for perhaps 7 years, and I've never fried a single PIC after programming literally thousands of PICs. I'm not even sure quite how you'd do it. Prior to using a JDM programmer, I used a relatively expensive commercial programmer from Microchip, but it wasn't as good as the very cheap JDM programmerby sai - General
Perhaps you should just etch them yourself. It's not very expensive or complicated to use photo etching, and you'll get the levels of detail you need to test the real designs without paying the price.by sai - General
