Hi Michael, sorry for the late answer ... I was on holidays Yes, normally you should just connect the three wires following the photos and all should work ... have you already tried? What is the result? All work fine? Guglielmo

Go on TinkerGnome GitHub, download the firmware for your UM2 (for the standard UM2 is Tinker-MarlinUltimaker2-16.03.1.hex) then, connect the UM2 to your PC USB, start Cura and use the function to upload "custom" firmware. Select the .hex that you have downloaded and ... that's all Guglielmo

Hi, if you look in my old message you see two important pictures ... the firts one show the connector and the wire on the UM2 side (from the top: black, white, red), on the third you have the wire and the connector on the "filament monitor" (from the top: white, black, empty, red). So ... just open the pictures, look the wire position and compare with your wires Guglielmo

Then add that most filaments have tolerances of +-0.05mm in diameter which, for the 2.85mm diameter filament, is only a volume difference of 7.02% while for the 1.75mm filament there is a volume difference of 11.43% so ... with 1.75mm prints can have more variability ... And don't forget that you have a quite long "bowden tube" where you have to push a much thinner filament ... Guglielmo

To replay I take the words from the site of "Diamond Age Solutions Ltd" (a filament manufacturer) ... in the FAQ ... Quite clear Guglielmo

Please ... for respect for those who read this English section, still reply in English or open the discussion in Italian section of the forum On my UM2 I changed both the extruder (with the Bondtech), that the hot-end (with the Olsoon block), but ... remaining on 2.85mm filament which I consider much better than 1.75mm Guglielmo

Installed more than 6 month ago ... very, very satisfied. But remember that you have to modify and recompile the firmware because, with the Bondtech extruder, the insertion and removal speed are too high. Next you have also to change the steps per millimeter (all is well described in the installation notes that you receive with the extruder) If you don't know how to modify/recompile the firmware, you can download a customized version from the Bondtech web site. Guglielmo

Hi Johan, as gr5 said, the original firmware totally ignores what happens on pin PC7 of the ATmega2560 so ... the sensor work only if you install the tinkergnome firmware which monitor the pin (PC7) and pause the printer if it goes LOW. Guglielmo

Hi, yes, it is constantly installed on my UM2 and I have not encountered any problem. Guglielmo

Yes, I still use it The big problem with "esun pla" is that it actually becomes very brittle just after a few months since you bought it, so ... don't buy too much, but only the reels that you really use. Guglielmo

@Nicolinux: ... can I give you a suggestion ? One very nice possibility of the new IDE (if I remember well is starting from the 1.6.5) is to have "sandboxed" independent IDE ... you can have many versions of the same/different IDE and each one is totally closed i herself. To do that, on OS X (... where I'm) first give a unique name to your Arduino copy (eg. the last version, for me, is "Arduino 1.6.9 Portable.app"), next right click and select "Show Package Contents", next go to "Contents/Java/" and inside create a new folder named "portable" (so you have Contents/Java/portable/"). Close and restart the IDE ... you have a sandboxed IDE, totally independent from other IDE installation (so ... NO the same libraries, NO the same packages, NO the same boards, ecc.) very useful to create specific IDE installations. If you download the IDE 1.6.9, give a unique name, make "portable" (as explained), select "Arduino MEGA 2560", open "Marlin.ino" and compile ... you should have just one warning that you can ignore Guglielmo

Thanks derbroti, I didn't know the use of "package.sh" ... reading in it is pretty straightforward to derive the parameters to be modified into the source code to compile directly from the Arduino IDE without running any scripts. Guglielmo

@tinkergnome: mmm, I think (... but i could be wrong) that Nicolinux needs info (... and me too I would like to know) in which file you define for which kind of Ultimaker2 (std., Go, 2+) you compile the firmware and what are the parameters to modify. @Nicolinux: me too I'm on OS X 10.11.4 and, for my Ultimaker2 std., I just used the last version of Arduino IDE (1.6.9) to compile the Marlin code that you download from the tinkergnome github (... just tried now, selecting as board "Arduino/Genuino Mega or Mega 2560", compiled Marlin.ino with just one warning ) Hope this help (... still if I have correctly understood the Nicolinux question ) Guglielmo

I have sent you a message Guglielmo

... just downloaded, from GitHub, Tinker_16.01 source code and delighted to discover that can be compiled, without additional libraries and hassle, with Arduino.cc IDE 1.6.7 So ... modified UltiLCD2_menu_material.h to change the two values, compiled, installed on the UM2 with BondTech QR Extruder and ... everything works fine Guglielmo
