We have now a full Ultimaker S5 with material loading and air control. when a material filament break inside the loading station (where all 6 loading tubes converge in 1 tube), it gives a ER54 and we have 2 options : 1) disassembling the material loading machine, which requires to put the ultimaker with air manager on the floor, which requires to unplug and unscrew about 10 screws, and 10 cables (electricity, filament tubes and data cables). Once the loading machine opened from bottom, clear all filament ways (again minimum 4 screws and 4 tubes) 2) or test all the materials ways one after the other. This option could be fast if the button "load" would be active directly after adding a filament. but no, it is greyed out. why ? A second functionality which would really increase the diagnostic and usability is the "reprint last print". The function is available through the web interface http://myUltimakerIPadress/print_jobs ... so it means that the last print is saved in Ultimaker memory... so it would be possible to use it directly through the Ultimaker embeded screen I'm upset because I have lost 2 hours on this stupid error ER54. Which could have been 15min with these 2 functionality. But worse : the "load filament" was there in a previous Ultimaker (probably without the filament-loading-machine). And the reprint is also not very complicated...

I wanted to have my "single extruder" Ultimaker back, I though I just needed to place the 2nd Extruder (with magnets) outside my Ultimaker and config the firmware to disable 2nd extruder. But for each print, it heat the 2nd extruder and some mm of 2nd material flows... is that normal ? another question : since I changed the firmware, the adhesion for small part on the build plate is problematic (after the 10th test, I put some glue on my special coated aluminum buildplate which normally works with just pure aceton cleaning. Is there really no printing difference between the original Ultimaker firmware and the mark2 firmware ? Thank you

Thank you. So I just went to "machine Printers", then select the "mark2 for Ultimaker2" (should be activated to see the ...) --> "machine Settings" button. And here, I can change the parameter "Z (Height)" to 305 (which is the value set in "Ultimaker 2 Extended+" printer.

I know where I found the advice to use Cura 3.2 : it's in the Github folder, there is a "Cura-3.2-ressources" folder. Might I suggest some changes on this "Step 5 - Installing Mark2 firmware": the page might be renamed as "Step 5 - Installing Mark2 firmware + Software" you don't make any warning about "cura-ressouces" version. It seems there is 3.2 and an another one "cura-ressources". For which version should we use this folder ? Small tipping errors § "Adding the "Ultimaker Mark2" printer in Cura" : " which translates to "plugins / plugins / PostProcessingPlugin / " ("plugins/" is doubled) There you should find a new entry labelled "Ultimaker Mark2". : That's wrong, the new entry is "Mark2 for Ultimaker2" and appears in "others" ( I bet on "ultimaker" or "custom"...) Is it normal that there is non "mark2 for Ultimaker2 Extended" ?

I got it !!! I first retried with 3.4.1, and then I installed CURA 3.2 (and no 3.2.1) and it worked. Probably using the right firmware (extended+expension-board instead of just "expansion") helped So now, I'm going to follow all the "calibrations" steps. thank you.

Thank you. I have the expansion board (bought in Belgium 50€) and I have the extended UM2. so I have to use the " Tinker-Mark2-extended-expansion-board-17.09.hex " perhaps this will solve the problem. I try if few seconds!

Hi Mark2 community. First of course, I want to thank you for your big work on Mark2. The website is beautiful, the 3D models are printing OK (even if I could not print without support as advice in the website), and it's cool to have the expansion board availlable to buy. So I passed the most difficult parts : 1) mounting the 2nd printhead 2) connecting board, motor, printhead. Here I had to make 2 cables prolongations (temperature and motor). The heater cable prolongation was part of "mark2 board package", just had to strip insulation. and now, I'm blocked by firmware. first, it's not clear which one I need. I guessed that I need to use an "expansion" firmware ( for example : Tinker-Mark2-expansion-board-17.09.hex ). I'm not sure I want the "tinker" things, but it seams that the last version is only with Tinker. So a small "readme" file in the firmware folder on Github ( https://github.com/foehnsturm/Mark2/tree/master/firmware ) describing the option like "what does mean 'extended', 'expansion', 'dual', what is the changelog between the 3 availlable version, which firmware is the recommended one..." would be very appriciated I'm actually blocked by "uploading a firmware". I downloaded the last CURA version 3.4.1, and the "upload custom firmware" dialog just freezes after I choose the firmware. I used another computer with CURA 3.2.1, the same dialog say "starting firmware upload" .... but the waiting bar is falling in a infinite loop for more than 15min. when I tried to print after these test, I could prove that there no firmware damage/change have been done. Do you think I badly connected a cable ? should I use another CURA version (I thing I have seen somewhere 3,2, but I can't find where I read that) Thanks a lot in advance, and again, thanks for the job done.
