Hi Monty, mmm, no, I have not noticed these "noises" ... perhaps the screw that adjusts the distance of the ball bearing was too tight and requires a greater effort from the feeder ? Guglielmo

Hi gr5, for the AVR memory map (AVR is the Atmel series of MCU used on Arduino UNO, Mega, Leonardo, etc ... NOT in Arduino DUE, Zero, and other using ARM) you can read HERE. They use for the tutorial the ATMega8515, on the Arduino MEGA 2560 you have the ATmega2560 MCU which have : Flash (program memory) : 256 KB (of which 8 KB used by bootloader) SRAM : 8 KB EEPROM : 4 KB Hope this help Guglielmo

Sure ... In Cura ... layer_height = 0.1 wall_thickness = 1.2 solid_layer_thickness = 0.6 fill_density = 20 nozzle_size = 0.4 print_speed = 30 print_temperature = 200 print_bed_temperature = 65 filament_diameter = 2.85 bottom_layer_speed = 20 On the UM2 ... Filament Flow 105% ... as you cans see you have just to print slowly, temperature 200° and increase a little bit the flow Try and adjust depending on the results you get ... Guglielmo

... a while ago ... is ... 6 months ? 9 months ? 12 months ? Because, more and more, people here have problems with old PLA (> 9 months) that becomes brittle, rigid and very difficult to print. Guglielmo

Hi Scott, I don't use OctoPrint (... I still believe that USB printing is NOT reliable, but it is just my personal opinion), but, as also tinkergnome said, this should not happen so ... please follow thinkergnome instructions and open ad issue on GitHub ... ... and you help all the community to have a better firmware Guglielmo

With the Tinker firmware, when the sensor put LOW the PC7, triggers the pause menu (... exactly like if you choose "pause" from the control panel). Solved the problem, you have to push the "reset" button on the filament monitor and to manually resume the printer. You can read from HERE Guglielmo

@scottd listen to me ... ... one time you install "Tinker" firmware ... you never go back to the "official" :D Guglielmo P.S.: I hope ... maybe one day ... "Tinker" firmware becomes the "official" one

Sorry, but you're talking about two different things ... ... with your optocoupler you just detect that the filament is finish/broken. What the "filament monitor" do is much more complex ... with a "rotary encoder" he detect the movement of the filament (... counting steps per time) and can alert you also if something goes wrong and the filament can't move (e.g. nozzle clogging, filament grinding, etc. ...) !!! Guglielmo

@tinkergnome: :D... believe me, it works like a charm You have just to adjust the timeout to avoid "fake positive alert" (default 8 sec. is too short, go to 20/25 sec.) . Yes is expensive but ... the time to make the board, to mount, etc. etc. ... not worth it, better buy it Guglielmo P.S.: the only annoying thing is that you need to remember to reset the sensor before each print.

Yes, sure Just because I have made many tests and these are the settings that have given me the best results Please ... keep in mind that I have old roll of PLA/PHA ColorFabb (more that 9 months) and, although closed, are still aged and are still more difficult to print than fresh ones. Guglielmo

I'm not a big GitHub expert, so ... I hope to have done properly ... HERE Guglielmo

What about adding a simple switch (on/off) in Cura General Preferences to rotate or not ? Should be quite easy and anybody can choose Guglielmo

... and I would like to add that, today, after many prints, the only real negative point that I found on ESUN filaments is ... that they age even if sealed in their original packaging and, after 6/9 months, become brittle and difficult to use. :( So, don't buy more than you need Guglielmo

ESUN it's only a difficult filament which requires patience and time to figure out the right parameters for printing. For me too, at the beginning, was a nightmare, but, after spending one week changing speed, temperature and flow (... with the great help of one of European distributor, La Boutique du 3D), now ... (25 hours print) Guglielmo

... maybe is not coded as a series of "gcode" commands, but directly as a "motor movements" instructions inside the firmware. It runs if, at the beginning of gcode, is found the statement ";FLAVOR:UltiGCode" ... Guglielmo

Mmm ... I suppose they are these HERE Guglielmo

Nice to know that you have solved Guglielmo

I suppose you download from HERE and I'm quite sure that they were designed with OpenSCAD, so ... will be nice to find the .scad original files Guglielmo

It's exactly my file ... Spiral-02 But, if I scale down to 150mm ... I can't print (... probably because of my other settings and because I'm using a 0.6 nozzle) Anyway is never a good idea to scale an STL file ... you must preferably start from the 3D model and scale the model, then export in STL Guglielmo

Can't see your "Enable combing" ... ... my Expert Config is (ignore my fan settings, leave your) : Guglielmo

@edis Can you show all your Cura settings ? Because I just tried now with Cura 15.04.2 and I don't have this problem ... Guglielmo

Nice and useful , but the "Tunell Monitor", as the name says, is different and does much more because he monitors the movement of the filament and automatically pause the printer not only if the filament is missing, but also if the filament is not moving for a certain period (e.g. clogged nozzle) Guglielmo

Quick answer ... with a 3D CAD Going back to being serious, what is your "experience" with 3D design? If you are a "beginner", it is probably easiest to start with something simple ... e.g. you can try Tinkercad ... is on-line (you do not have to install any software), is quite easy and is "free" Guglielmo

Should be THIS one Guglielmo

@tinkergnome: After 2 days and some prints I can confirm you that all is working fine Guglielmo
