Definitions." defines: This License Copyright modify covered work propagate convey interactive user interface Then follows section explains what source code is. In whole document there is no string "private use", while term "use" is routinely used throughout in many phrases like:by miso - General
@vegasloki: Yes, that kind of use is allowed by GPL. Its just both licenses (GPL, NC) put some restrictions, or conditions that one has to obey. on use. You can use NC protected material as long you stay noncommercial. You can use GPL protected material, in your software, as long as you wont distribute it, or if you do, you have to distribute complete source. That especially comes up with librby miso - General

You can't use GPL software to make your own closed source one.by miso - General
Quotebobc Open Source is a formally defined thing, it is not just a woolly concept that you or I might want it to be. All Open Source licenses allow "for any use". It is one of the defining features of Open Source that distinguishes it from Closed Source! No Open Source organisation will ratify a license as OS if it includes a "restriction on use" clause. Just out of curiosity, about definitionby miso - General
Basic physics says that acceleration determines the amplitude of driving force and, if you want amplitude of oscillations to remain constant, it should be inversionally proportional to system frequency response. Constraining acceleration to constant value throughout whole frequency range results in inefficiency - it will be unnecessary low for frequencies far away from resonance. I don't say thatby miso - General
Why to ban just sale, when they can buy possession? And put nice 5 years penalty on it. That will make wonders. And how will they track it? I don't know, but that's not my area of expertise. There are people that are educated and trained to do it, and I guess that they are pretty good at it. That's just like with tracking those TVs, layman would say so its not possible, unless they can see screenby miso - General
I would say that heat insulation of fridge is much better than that of oven. Fridge is designed for continuous 24/7 operation, so it makes sense to provide better insulation, and it doesn't have to withstand high temperatures. Also ovens have quite high thermal capacity. I think that best material to build heated chamber are polystyrene foam tiles, like the one used for thermal insulation of builby miso - General
Linux allows files (including character devices) to be opened simultaneously by multiple processes. First read removes data from the buffer so they can be read only once. Which process will read newly arrived data is determined by process scheduler, but saying that its at random is fair simplification. This makes possible for some process to steal data from another one, say avrdude what is then pby miso - General
Are you sure so there are no other processes concurrently reading serial port? You can use fuser /dev/ttyUSB0 to check. Also make sure that you use correct baud rate, bootloader baud rate may differ from the one that you use to communicate with printer firmware. Can you post output of avrdude command when it finds programmer but fails to read?by miso - General
I(C)SP is different from serial line, it works over SPI lines and requires special, though simple, hardware to use. On Gen6 board its 6-pin connector just over reset button. To program via serial (usb) line you need to have bootloader installed on board. In that case stk500v2 works fine as programmer for me.by miso - General
It should work, but you should check insulation strength and overall quality, 12V heater cartridge may not be certified to operate with 120V. Operating them at 120V may be life threatening, especially if not galvanically separated from mains.by miso - General

aduy: With pressure or similar sensor, firmware can sense as force is gradually approaching hobbed bolt limits and possibly take counter-action (adjust temperature, slow down extrusion). With sensor on idler you get signal only when its too late.Though I think so, using tensometric sensor to measure axial force exerted on hot-end (already done, there should be topic somewhere here about it) shoulby miso - General
QuoteOptimist Do you think the Polulu is capable of double current for the two steppers? It's commonly being done. Some electronics (Gen7) have only one driver for Z axis. You don't need much torque and thus current on Z axis, because its usually geared down by threaded rods. You can wire steppers either in parallel or series.

Check that you don't have cold joint on enable pin at carrier board. Or possibly short circuit on carrier board, remove board from ramps socket and measure enable pin resistance against logic GND. You should get aprox 90 kOhm. EDIT: Pinout pictureby miso - General
It works for me. Key is to use tape designed specially for heatsinks.by miso - General
QuoteLoboCNC This is something that I feel the company making money off of Marlin (the board manufacturer) should provide - basic documentation about what their product is designed to do - even if they aren't providing the firmware themselves. I think so many of them do, they (I hope) provide MCU pinout, some of them even schematics and PCB layout. Firmware is completely unrelated, they can hardby miso - General
Have you checked your idler tension and hobbed bolt? When filament strips its likely that it will leave chips in hobbed bolt grooves that negatively impact grip. Also check if there isn't some debris inside hotend partially blocking nozzle.by miso - General
There's a lot of difference between technophobia and understanding how technology works. People generally don't t care how technology that they use everyday works. Look at technical shows/documentaries in TV, they are becoming less and less "technical". Look at promotional materials of car manufacturers.

That's because 3D printing is becoming increasingly popular and readers thus media generally prefer negative information.

Also check if you have no backlash from loose belts or worn bushings. You can rotate motor pulleys by hand and closely observe if it immediately transfers into linear motion of printbed/extruder carriage. You can also print cylinder, and check if first layer really comes out as circle, and not rather like ellipse.by miso - General
QuoteuGen so, the last question for me is: how is Makerware structured? Attaching filelist. Its just 7zip extracted, so expect slightly different structure when properly installed. Skeinforge version used is 12.03.14 (version.txt) respectively 12.03.15 (http://fabmetheus.crsndoo.com/).by miso - General
Dark Alchemist: I am not personally familiar with Makerbot case, I was merely stating, that the facts named in uGen's post, alone, AFAIK are not proof of GPL violation. So its possible, again I am not familiar with specifics, that, what you call theft is in fact fair course action, in accordance with authors (Enrique Perez) free will (hopefully he read, understood, and chosen AGPL voluntarily), oby miso - General
uGen: Author can licence his work under multiple licences, this is being routinely done. So its no problem for original author to later close once GPLed software, as long as his work isn't itself GPL derived. Packaging together GPL and closed source software shouldn't be problem either, as long as source code and license for GPL part is provided.by miso - General
