Even though there are upgrade on Ubuntu 14.04, for the most part, its only security fixes. If you are using 14.04, of course the problem will still be there. This is because of the development model Ubuntu uses is more of a "frozen cycle" model, there is pretty much no software versions changes unless you change to a newer Ubuntu release. This is done to help stabilize the whole system, and to loby swe3tdave - General
From this article: [3dprintingindustry.com] There is apparently a way to produce lactic acid 17 times more cheaply. Hopefully it involves more simple steps... The paper is available here: i dont understand any of this stuff so i hope someone has access to the paper and can tell us what processes it involves.by swe3tdave - Polymer Working Group
well, i only tried black ABS so here goes away my part of the complaining.. What are you guys using as an extruder? I've had problems with my E3Dv5, i changed the heat break two times because the smallest part always ends up curved inside and it clogs like hell. One bad setting in slic3r and you end up with a few bumps on your part, that seems to be enough to wreck it(the heat break)... ABS dby swe3tdave - General
i went through the trouble of trying my best to give my 6kg of ABS a chance. i didn't know what i was getting into when i bought it... i went through the trouble of buying a PEI sheet, i even built a wooden box for my delta... it did help with the small parts though, but the quality i was expecting is just not there. Impossible to get rid of the stringing completely, large part always curl and tby swe3tdave - General

look if its hidden in a folder in /dev, i've seen that in a few old version i think... unplug your 3d printer and plug it back and give me the result of: dmesg EDIT: you can use paste.ubuntu.com or attach a txt file, you can generate it with: dmesg > dmesg.txtby swe3tdave - General
to connect to your 3D printer using 250000 baud rate, you need pyserial 2.7 or better. the package's name in ubuntu is python-serial or python3-serial or you could try connecting at 115200... as for the COM port, on my PC its /dev/ttyACM0 you can also try /dev/ttyUSB0 as for skeinforge location try: whereis skeinforge it should give you the location /usr/bin/skeinforge you can also try Slic3by swe3tdave - General

oh and i just realized, there is a package of pronterface for your version of ubuntu... so try it first sudo apt-add-repository ppa:richi-paraeasy/ppa sudo apt-get update sudo apt-get install pronterfaceby swe3tdave - General
Your version of Ubuntu is a bit old, if you have 12.04 its 2 years and 6 months old... if its still not working, check the requirements: you can use synaptic to verify the installed version of a package. If you see something is lacking you're going to have to install that particular package from source... Did you try installing 14.04 with forcepae?by swe3tdave - General
the installation is supposed to make you enable to start pronterface without going into the folder and running ./pronterface.py this is what i get: swe3tdave@server:~$ pronterface.py Traceback (most recent call last): File "/usr/bin/pronterface.py", line 32, in from printrun.pronterface import PronterApp ImportError: No module named printrun.pronterface it does work when running fromby swe3tdave - General

did you make a bug report on the github/issue link i gave you earlier? and even before that, make sure you are running the latest github version... and yes, i agree with isonoob, you might have more luck with repetier host.by swe3tdave - General

seems like a missing dependency, sometimes a needed package get flagged as "suggested" instead of "required" and is omitted when installing. i suppose you followed this page? It might be a bit outdated... (it didn't work for me since i run 14.10) In any case, the GCoder line is not the issue here, its the DBus.Error that's bugging me... might be related to a missing library...

My bed heater is home made, with nichrome wires, 24 gauge, about 350 inch, at 120VAC, its about 300watts. Since there is no power supply, its hooked up directly to the wall with a relay in between. I calculated that the max temp should be at 250-270°C, so it is fine wiring it with kapton tape. i did install muffler tape as well because i had a problem once when the thermistor got off the plate, mby swe3tdave - General
for those having a problem with slic3r in linux, look on the slic3r.com web site and download the binary version you will find there... uncompress and run Slic3r/bin/slic3rby swe3tdave - General
Unless there is a bug in the Linux Kernel, or somewhere else, there is nothing that should prevent you from connecting to an arduino at 250000. With that said, in the case of Ubuntu 14.04, the problem is the use of pyserial 2.6 that does not, normally, include the patch to allow the use of custom baud rates in python programs. For those with other GNU/Linux versions, the next version; pyserial 2.by swe3tdave - General
i had similar problem with abs filament from filament4less, there was too much water in it. i bought 500g of desiccant from my hardware store and stored my abs with it in a sealed container. It took a week before i could finish a print.by swe3tdave - General
i think that you could think of it this way. If you go back in 1976-77, you would be asking the same question about computers... Was that the right time to buy one? It depends on what you would've bought, and what use you would've made of it. But it would've been easy to regret not getting in the train when the time was right. I can't say for sure, of course, that 3D printing would generate the sby swe3tdave - General

sorry for not replying to you sooner, an optoresistor is a device that looks at the quantity of light that reaches it, what makes you think it would be better than an encoder? and did you even read what ErikZalm said? he said that the electronics he tried worked perfectly. so the encoder is the way to go, and he is looking at a good bearing or wheels combo i guess i could say, that correctly convby swe3tdave - Developers
Delta printer being what they are, it would be a lot better if we could have a sensor, optical or mechanical, so that we could adjust the extrusion automatically. Does anybody know of a reliable way to do this? An Optical mouse sensor is the first thing that comes to mind but it might be too unreliable. there was small discussion here about it, but since the request as been closed we will contby swe3tdave - Developers
when using a pressure sensor like the dynisco, i think the hotend would need to be built around the sensor. it would double or tripple the size, that particular sensor is for a 7 or 8mm extrusion... i doubt its sensible enough for our needs.by swe3tdave - General
i dont know if this is close to what they are doing with linuxcnc, but i found this: Modified Slic3r for Bowden i'm not sure about my settings, but it does seems to help a lot.by swe3tdave - General
how about using a current sensor to monitor the motor current being used by the pololu board itself. i dont know about the coding needed in marlin but the wiring should be simple enough. using a board like this: i dont know about sensitivity though, 185mV/A of sensitivity, what does that means? i suppose you divide the mV/A by the voltage you are using, that would mean 15.4 mA of sensitivity aby swe3tdave - General
there are two diode on the ramps, the one located under the pololu, you need to remove it if its still there. If its not there, or you already removed it, i do not know what's going on, i suppose there might be a weird feedback somewhere...by swe3tdave - RAMPS Electronics
