I had been working on this for a while. I came across some helpful libraries and ideas scouring old posts. Here is some code I came up with. You may have to tweak your thermistor and hardware, I deviated a little since I had to write my own. I am able to change speed and temp with buttons. I got myself an IR thermometer so I could double check my temp. Stune is what I used to set the values for tby bartlee45 - General

TLDR: z axis not working after configtool upgrade from 91.6 to 91.7 Previously I manually updated to version .91 manually and then used the configtool to upgrade around March 3, 2014 with no real problems. Now I wanted to upgrade again, seeing some changes/fixes. I used the configtool and uploaded my previous configuration file and then downloaded the complete firmware.

Another thing I found after more looking Should have used ORIG_FAN_PIN which is 9 to get fans working again, I believe. Also saw what I believe is a mistake: new not working #define ORIG_Z_STEP_PIN 46 #define ORIG_Z_DIR_PIN 48 old was working #define Z_STEP_PIN 44 #define Z_DIR_PIN 46 I am changing in mine to #define ORIG_Z_STEP_PIN 44 #define ORIG_Z_by bartlee45 - Repetier
I was trying to upgrade to latest firmware code. Went through online config tool, got latest firmware master and placed Repetier from that inside master to mimic the 0.83 that I had previously. Then I thought I was all set, but got an error relating to fan pins. I noticed that I had #define FAN_PIN FAN_PIN #define FAN_BOARD_PIN -1 I changed that to #define FAN_PIN -1 #define FAN_BOARD_PIN -1 aby bartlee45 - Repetier
I had wondered this all along and have come to these conclusions. It seems that the sturdiness of the motors and the mauling of the filament is what makes it work so far. I shouldn't be surprised that if you have varying thickness of filament you wouldn't notice much of a difference in the output. Output should be the right size and as long as the pressure is sufficient. At a lower limit if yourby bartlee45 - General
AOI (with approprite addins) supports Wavefront in and out so you should be able to use that as transfer medium between Autodesk Inventor (with approprite addins) and AOI.by bartlee45 - General
I was looking at some circuits and this caught my eye. This puts a finished touch on a project.by bartlee45 - Mechanics
The utility that I have seen as others have pointed out would be in a cardridge. If you had a cartridge of rods and a mechanism for inserting the new rod as needed, then you could walk away as long as your cartridge didn't empty or you didn't run out of cartridges taking the next step. Those will be improvements down the line maybe, depending on needs. Maybe the soda bottle on a swivel will be goby bartlee45 - Reprappers
If only we had some mechanical engineers to comment on the feasibility of removing more material as appropriate from pieces with bulk. Maybe someone familiar with the current design, and having experience with creating and modifying AOI/STL models. Say, who was it that made those cute little RepRap logo drip holes in the parts. Wonder how much plastic and therefore extrusion time could be squeezeby bartlee45 - General
Yeah, really nice. Looks like over engineering a bit, but when you have a mill, you mill stuffby bartlee45 - Reprappers
I think the joining one end to another wouldn't be a big problem as long as you can thread in the new material before the old one leaves the threaded piece (maybe as soon as you can, maybe a sensor to warn/activate next feedstock), at which point pressure ceases. If you get the new piece in in time, it will follow behind the first one and push it out. That is assuming that the path is able to beby bartlee45 - Reprappers

If you are missing any packets, I would say that it's likely hardware. Make sure you don't induce any noise. The caps are supposed to handle it. Do you have any potential noise sources you need to isolate from the circuit via shielding etc?by bartlee45 - RepRap Host
Cygwin does work on xp. I think I've posted info on where to get started. I went with the info found in the manual for sdcc setup.by bartlee45 - RepRap Host

Maybe a design time add-in honeycomb selected area. And it could just bore hexagonal holes in a pattern mating up to the enclosing area. You would have to carefully chose x, y or z axis as well as enclosing area and width of walls for appropriate strength etc. We could even do this with existing designs we have.by bartlee45 - General
Yup, this is a hard one to remember. Even after converting lots .stl files I still forget sometimes and try to open it. Only option for .stl is importing. You can naturally export or save in other formats as you choose. I think Adrian posted in the AOI introduction what addins you need. I may have posted recent info on how to do it relating to the cleanup we did.by bartlee45 - RepRap Host
That would be worthy of whole new technologies that are currently being pursued academically and industrially. Just producing the circuit boards and some motors would be a real good start and that will still take a lot of figuring out. I love the idea of printing parts but we will need lots more precision and control. Something to look forward to down the road.by bartlee45 - General
Can't discount bad or intermittent connections. This might include loose/broken/nearly-broken wires, contamination on sockets/pins etc. Glad you have it working. Sometimes just reseating components wear off a slight oxidation layer. I was in component testing for a while and saw that there were all kind of weird effects caused in trying to test circuits. At low voltage an oxide layer can form a rby bartlee45 - RepRap Host
Could it be a noise issue on the Y-axis? Make sure you have bypass cap. Maybe try swapping cables?by bartlee45 - RepRap Host

It's not an afterthought, its been bounced around quite a bit. It is 3D scanning that brought me to reprap. I found the scanning articles and started fanning out and looking at the methods and got some ideas about how they worked. Then I sat back, well 3d models are all very good, but what do I do when I have a model. And this was the answer that I found to that question.by bartlee45 - 3D Scanners, Book Scanners, and Optics

Hmm, thats a long one, but I was encouraged about the part that stated bright zinc deposition with or without added cyanide. We certainly want to be as safe and green as possible to allow the widest acceptance. Thats because after reading the howto's for plating, they say don't even think about doing this at home. Well if we can find relatively safe methods, we can decide for ourselves. We just dby bartlee45 - General
VPP does not need current, the PIC develops it's own programming voltage internally. The applied vpp is only a reference voltage. This is from the 16f6(27/28/48)(a) specs. Yeah, I like circuit 2. Nice and simple. Now what I'm not sure of.. can we do ICSP on connected boards, and do we need any protection from running (programming software of choice) while reprap is powered up?by bartlee45 - Controllers

I got a bunch of the stuff a while ago. I tried heating it up with my ~$20 oven (which I got per your suggestion) when I was melting some plastic bottle caps. I was hoping I could make some nice looking red parts with them, still have to see if that can work. But I did find out that nylon bubbles when it gets hot and I'm not sure if that happens as it gets too hot or shortly after it starts meltiby bartlee45 - General
