What I would like to see in Cura is a change in the Post-processing plugin, that it checks whether a given script is supported by a given Ultimaker printer. As Cura is an Ultimaker thing, it is perfectly fine to only check for Ultimaker compatibility. Now the case is that almost none of the Post-processing steps work on my Ultimaker 2+ Connect for instance, so that change would be cool 🙂 Also, I would recommend people NOT to use post-processing scripts at all, or only use it when you know what you are doing. Maybe make it an Expert only section for instance, that you can only access when you start Cura in Expert mode?

Confirmed now that M0 and M1 do not work. What I have also confirmed is that you should not fiddle around too much with the gcode if you are using a Ultimaker 2+ Connect. The M104 and M109 are problematic commands and somehow it seems they are not properly implemented. Sometimes the printer just hangs and can only be restarted by a flip of the switch. The same gcode runs fine in other occasions, so that is weird. Somehow waiting for cooling down with M109 R90 for instance also does not work. Anyhow, I will stop experimenting to prevent the printer from getting ruined and basically you dont really need to fiddle around, only when doing multicolor prints 🙂

Here is the result:

So yeah, the following worked for me, I had enough time to change to black filament, push it through manually, flip the lever, clean the nozzle and it started printing the black part perfectly 🙂 Only thing that could be added is a nozzle cooldown to 90 degrees, do a cold pull, heat up the nozzle again and push through the black filament. That way you unclog the nozzle too. But I don't need that right now. Here is the code for you guys and gals wanting to change filament during print for instance and have no pause function on your printer: ;FILAMENT_CHANGE_SCRIPT_START G0 F1000 Z1.0 G0 F1000 X0.0 Y0.0 G0 F1000 Z200.0 ;MOVE UP AND DOWN A FEW TIME IN MM/MIN, TIME TO CHANGE MATERIAL = 2 minutes (if the feedrate is indeed mm/min) G0 F60 Z170.0 G0 F60 Z200.0 G0 F60 Z170.0 G0 F60 Z200.0 ;TELL THE ENGINE THAT THE EXTRUDED POS IS ZERO NOW G92 E0 ;MOVE SLOWLY TO THE RIGHT (SO NOW YOU HAVE TIME TO CLEAN THE NOZZLE) G0 F60 X50.0 ;EXTRUDE TO ZERO POS G1 F1500 E0 ;MORE TIME TO CLEAN THE NOZZLE G0 F60 X0.0 ;FILAMENT_CHANGE_SCRIPT_END

Thanks for your extensive reply gr5! Yes unfortunately M0 did not work, I am almost sure, but I will give it another try to be certain!

Yeah the pausing is a problem though, as it takes a long time to click on the skip cooldown and then the change material etcetera. I am going to try some stuff now and will post it here, so maybe others can benefit from it too 🙂 I tried to create my own Cura build yesterday, but couldn't get the Docker buildchain running, so I am going to invest some more time later on maybe to make a native buildchain, but maybe I will also stick to S3D.

Ah yes, well I also really love the Ultimaker 2+ Connect, excellent and reliable prints and a bottom surface that is jaw-dropping 🙂 The thing is, now for the first time I am printing a foil, consisting out of white letters and a black background (it is for an Enigma machine) so I need to first print the white letters, then change material and print the rest. Unfortunately Cura does not let me print two objects on top of eachother, so I need to merge the gcode manually and put some pause in between where I can change material. So as there is no pause possibility, I just add gcode to move the extruder up and down slowly and during that process I simply pull out the material and push in the new material until material comes out. Of and before that issue a gcode command to set the current E value to 0. Only way I can think of doing this without the bed/extruder cooling off too much. If there are better ways I would gladly hear them! Oh and probably I will use Simplify3D, as I cant get Cura to print just one layer, somehow it is always a minimum of two, no matter what I change in the settings.

Aaaah that explains it, cool 🙂

Awesome, thank you so much! Where did you find this? Unfortunately that means I cant pause my printer using gcode 😞 A workaround I though of is moving the Z up and down with a very low feedrate that takes a while and then I have time to change filament. I dont really understand why something like the filament change command is not supported. I do understand the Arduino/firmware situation, where you cant control the lcd from the gcode, but then again…printers like prusa also have kind of the same situation but there it works right? I understand though that the 2+ Connect is geared towards the “just print my stuff without tinkering” people, so i understand the less dependencies the better.

Hello, Something I havent been able to find anywhere, also not on Github is which gcode commands are actually supported by the Ultimaker 2+ Connect machine? For instance, when I look in the supported gcode commands of most of the Ultimaker machines on Github I see support for the G4 dwell command and for the M600 command for instance. Both of these do not work on the Ultimaker 2+ Connect. So I would be very happy to get a correct listing of supported gcode commands for the Ultimaker 2+ Connect Thank you very much in advance 🙂

@fbrc8-erin thank you very much! I will also tell my reseller this, as presumably they are not aware of this. I am looking forward to the exact explanation from @Szahari if he/she would be willing to explain.

These replies help me alot!! Thank you very much @gr5 and @fbrc8-erin I indeed have the GST power supply. I wanted to experiment with lower bed temperatures for a specific type of PLA. I try the workaround and will also ask my seller for a new power supply, because the printer is 1 month old.

Hi! i have a brand new Ultimaker 2+ Connect and whenever I set the bed temperature below 60 degrees celsius and start a print, the preheating process starts and after a few seconds the printer shuts down and reboots. So, basically I cant set the heatbed to temperatures lower than 60 degrees celsius 😞 Above 60 degrees no problems at all. Anyone recognizes this problem and might know what to do? Thanks in advance!

I just bought a new Ultimaker 2+ Connect and I noticed that I hear a clear sand grinding noise when the bed is going up (either manually or automatically). What could this be and how can I fix this? Everything is lubricated correctly. Thanks for the help!
