You're welcome... :smile: The issue with copy the ini files is that one should deactivate all plugins before version change. Otherwise it's looking for an old plugin which might not exist in the new installation anymore and will block newly selected plugins from working. However, on the next start of Cura the issue seems to be solved automatically.

Falls Du Dir nicht die extrem mühsame Arbeit des Direkteditierens machen willst, benutze doch einfach ein Cura Plugin, z.B. das TweakAtZ-Plugin, das ab Cura 14.02 Teil des Standard-Cura-Umfangs sein wird. Bis dahin findest Du das TweakAtZ Plugin natürlich auch auf der Ultimaker Wiki.

Safety by hardware is always better than safety by software. It's e.g. higher rated in safety checks for a CE declaration. The 20k pull-up resistor would mean changing the Marlin configuration tab; maybe extending it with a 'new' sensor type.The values themselves could be calculated with a small spice simulation. It might get nasty if UM would decide to deliver future UM1 with such a hardware modification. A version check by the firmware must then be possible.

Daid, thanks for this very interesting update! I've read about the project but this is the first picture of a printed part I see. But I think most of us would have some troubles finding a happy corner for THAT printer. So please, don't exaggerate for the Ultimaker 3... :shock:

I see now where the EOL character issue comes from. I guess you do these three clicks on a Linux machine. Then the Windows version also gets the terminal character of Linux.

I would rather vote for a solution which physically stops the floating. As Daid has pointed out, the floating could be quite small and setting limits wouldn't trigger anything. On the other hand, floating could be large and then the hotend could get very hot within one minute (as it usually needs two minutes from room temperature to 200°C). Certainly the issue has some seriosity as Jonny has clearly pointed out. I don't know about other RepRap electronics, but maybe other boards running with Marlin are not that different for the temperature sensing. So the issue could be far more widespread than 'just' within Ultimakers. Depending on your workload, Daid, it might be an idea to put that generally into the Marlin developer group?

Could you please give me the numbers you put into the plugin and the approximate dimensions of the print to which you want to apply the plugin? I would like to reproduce the problem with RC3.

I agree. Maybe my text was misleading. With 'postprocess plugin' I simply meant a standard Cura plugin.

Just to confirm I got it right: the connection between amplifier board and UM shield is broken, not the connection between thermocouple and amplifier board?

Hopefully still like an Ultimaker and not like a noname ugly box from China! :eek:

A look at the different criteria is also very interesting. Especially to see where Ultimaker is best in class and where it is second worst...

Maybe you get them also as fast if you buy ten at a time?

What about displaying the amount of material seperately for two extruders? This might be something for the new Cura GUI (although I somehow have a feeling it has been already thought of... :cool: )...

I guess this printer is rather printing concrete than PLA...

I just read somewhere that PVA should be printed without cooling (I guess this means fan off). Is that true? What's the issue with cooling and PVA?

Daid certainly has... :wink: It was discussed earlier somewhere in the Cura subforum if there should be the possiblity to change layer height throughout a print. If this is implemented some day, it most probably has to be in the slicer engine directly. There was once the idea to allow not only postprocess plugins but so-called UI-plugins which directly affect the slicing process (if I didn't get it completely wrong). However, I see a possibility for a 'simple' postprocess plugin which replaces e.g. two layers of a certain height with one layer of double the height using the x- and y-coordinates of the lower layer. It could be restricted to a start and end height or layer no. respectively.

@Zungara: Meinst Du das blaue Malertape von 3M für delikate Oberflächen? Das hat die Nummer 2080 während das 'normale', was Ultimaker beilegt, die Nummer 2090 hat. Das 2080 hat auch eine etwas feinere Oberfläche.

OK.... could you please specify 'not working': no gcode change or do you get an error? Errors are visible at the end of output.txt; but you have to close Cura for having this file updated.

The terminal character bug is not yet fixed in RC3.Might be the way it was compiled rather than the source code? This one is also not yet fixed in RC3. I hope for RC4/final version... :unsure:

Did you copy the ini files from an previous installation to the 14.02RC2?

Forget the fans. It's mostly the steppers. There is a reason why they get hot (up to 60°C). Daid recently posted that the standard adjustment of the steppers is about 1.1A. As it is driven with 19V (in steps down to 12V and something like 2-3V, but I think the voltage is not transformed but divided, isn't it?) this makes something around 20W per stepper. And as there are 5 steppers enabled and the electronics itself needs 14-17W the number makes sense... But don't forget that I measured on the primary side of the PSU. The power factor of 0.86 might also be overestimated. I think the accuracy of the measurement device relates mostly to the power measurement and maybe less to the measurement of the power factor.

Only one hotend was actually heated during the measurement.

I assume your office notebook runs with Windows. It's in c:\program files (x86)\Cura. And you have to close Cura in order to have it updated with the last messages. And good luck! :cool:

You can use the ooze shield for that purpose... minimum material waste...

I made some measurements on the primary side of the UM PSU. I used a device which was found to be very accurate in a independent test (Brennenstuhl PM231). And it said that while printing, the primary consumption is around 160W and the power factor 0.86. Further measurements showed that the 75W might be the power needed when not heating the hotend. I also have to mention that my UM1 has a dual extruder. Maybe you know that the idle extruder motor is always enabled as well (something I intend to bring up in the Marlin developer group sometime soon).
