I'm currently trying to get some movement into this issue on Github. I just left a comment there... Preheating the bed is of general interest, I think, as e.g. Cura first heats the hotend and then the bed (yes, I know the work-around by using the start.gcode... ).

As I was one of those who could not wait until the official kit arrives, I've built my own heated bed. It offers the possibility to print on the surface of choice. I started today with 3mm Aluminium with Kapton tape. Great stuff! The PLA I printed on it is sticking very well (maybe even too good). I could easily lower the print temperature for the first layer. Ok, as you guys usually want to have a photo... :grin: Here it is:

The code works as it should. As I now have a heated bed, I also added a menu item 'Preheat XXX Bed' to both XXX=PLA and ABS. Sometimes it's very convenient to have the bed preheated separately...

L'option que tu cherche est peut-être celui là: Advanced -> Cut off object bottom... Si il n'y a pas 0 là, tu enfonce l'objet ...

Ooohhh... silly me! :wacko: It was a typo in the name 'script.py'... I have it now. Thanks for the assistance!

Line width and Slic3r reminds me of a http://www.extrudable.me/2013/11/03/slic3r-strange-defaults-causing-qu-bd-woes/. There he is writing about line width settings in Slic3r. Maybe you found settings in Slic3r which give you a nice result with the original (0.65mm I think) line width settings? Taking all other settings such as e.g. a tweaked filament diameter to Cura which doesn't know a line width setting would then result in too thin lines. It's just a rough theory... :wink:

I included it in my personal Marlin code as I had to recompile it due to the new heated bed. The menu looks good so far but further tests are needed.

Das klingt sehr stark nach 'Pillowing': In diesem Fall ist die Kühlung der Oberfläche zu schwach. Ich vermute, es handelt sich um einen nicht allzu hohen Print? Die Standardeinstellung von Cura im Full-Modus lassen die Lüfter (UM2 nehme ich an?) nur langsam hochfahren und erst ab 5mm die volle Stärke erreichen. Das kann man in den Expert Settings (Ctrl-E) ändern. Ich persönlich drucke mit meinem UM Original immer die erste Schicht ohne Lüfter danach mit 100% Lüfter-Kühlung. Auf welchen Wert habt Ihr denn das Heizbett eingestellt? Einer der Moderatoren hier im Forum, gr5, weist immer wieder darauf hin, dass der Standardwert von 75°C für PLA zu hoch ist und empfiehlt schrittweise auf 70°C, 65°C, ev. sogar 60°C zu reduzieren.

Very nice summary about thermal imaging, gadgetfreak! :smile: You may add another point to be taken care of: the background. It is reflected on the part you are observing (although you don't see any reflection in visible light at all) and should therefore have a reasonable temperature (room temperature). An open sky as background is e.g. very bad (-80°C). :wacko:

@owen: I just did as you wrote. The new 'Pronterfan' option does not appear in the preferences. Only 'basic' and 'Pronterface UI'... what am I doing wrong? Tried it with RC5...

Maybe some of you have seen it as well on Github. Quite a lot of open Cura issues have been closed today by Nallath. There also seem to be new / modified issue policies since today / yesterday. As Cura gets a new GUI, I can understand that issues which will be solved by implementing this new GUI are closed. For some of the closed issues, the relationship to the GUI is obvious, for others it is not (at least not for me). Thus, I would like to express my slight concern about this 'new' way to deal with issues submitted by the community. I hope, that Ultimaker is following the up to present path of improving the software together with the community. If this is the case, the Cura road map, which is mentioned in the issue policies, should maybe be published. If it is already, Daid and Nallath, please provide a link. I think everybody is aware who has written this excellent software called Cura (for the few ones who don't: Thanks Daid!). However it might not be completely unfair to say that this community had its share in the success of Cura. And I guess many of us, including me, would be glad to help improving it further. Please let us. Thanks!

There is no 3D assembly a.f.a.I.k., but you may find step files of all UM1 parts here: https://github.com/Ultimaker/UltimakerOriginal

What time range are we talking of by 'early' or 'at the beginning'?

Everything is possible... :wink: For an Ultimaker, two extruders are right now the maximum, I agree. But Standard Marlin has to stay open for the other RepRaps. It might be possible to limit it for the UM2-Marlin which has, a.f.a.I.k., a separate software repository due to the UltiGCode.

It's correct. There is no filament diameter for an UM2. You would have to switch the GCODE flavor to RepRap. Edit: I was only referring to Cura...

at the bottom of the basic settings tab

I found the Colorfabb filament to be quite temperature-sensitive. At what temperature did you print it? Did you check the diameter and adjust it in Cura? I remember Colorfabb filament to be thinner than other filament I have.

Nice extension...! :smile: It's a good idea to collect print interfaces in this thread for the moment. However, on the long run, I would see a new 'Cura print dialog plugin' category in the Ultimaker Wiki where the designs could be collected... similar to the 'standard' Cura plugins.

I just could compile it with #define EXTRUDERS 1... I then also set TEMP_SENSOR_1 = 0 and the problems began... but it can be solved: two functions in ultralcd.cpp have to be adjusted: static void lcd_preheat_pla_menu() { START_MENU(); MENU_ITEM(back, MSG_PREPARE, lcd_prepare_menu); MENU_ITEM(function, MSG_PREHEAT_PLA0, lcd_preheat_pla0); #if TEMP_SENSOR_1 != 0 //2 extruder preheat MENU_ITEM(function, MSG_PREHEAT_PLA1, lcd_preheat_pla1); #endif //2 extruder preheat #if TEMP_SENSOR_2 != 0 //3 extruder preheat MENU_ITEM(function, MSG_PREHEAT_PLA2, lcd_preheat_pla2); #endif //3 extruder preheat #if TEMP_SENSOR_1 != 0 //both extruder preheat MENU_ITEM(function, MSG_PREHEAT_PLA012, lcd_preheat_pla012); #endif //2 extruder preheat END_MENU(); } static void lcd_preheat_abs_menu() { START_MENU(); MENU_ITEM(back, MSG_PREPARE, lcd_prepare_menu); MENU_ITEM(function, MSG_PREHEAT_ABS0, lcd_preheat_abs0); #if TEMP_SENSOR_1 != 0 //2 extruder preheat MENU_ITEM(function, MSG_PREHEAT_ABS1, lcd_preheat_abs1); #endif //2 extruder preheat #if TEMP_SENSOR_2 != 0 //3 extruder preheat MENU_ITEM(function, MSG_PREHEAT_ABS2, lcd_preheat_abs2); #endif //3 extruder preheat #if TEMP_SENSOR_1 != 0 //both extruder preheat MENU_ITEM(function, MSG_PREHEAT_ABS012, lcd_preheat_abs012); #endif //2 extruder preheat END_MENU(); } It's not yet a proper solution as it would fail if extruder 0 and extruder 2 but not extruder 1 would be present...

There is no difference. PTFE is the abbreviation for Polytetrafluoroethylene, Teflon is the trade mark for this material by DuPont.

Thanks for the feedback. I will try it myself and check how to solve the lcd_preheat_pla1-issue as soon as possible... b.t.w.: I also found a way to switch off the unused extruder motor... it doesn't have to heat while doing nothing, does it?

No, you're right...the menu (and not the single commands for extruder 0) should be displayed if Sensor 1 is also present but not if only Sensor 0 is present... Maybe that's the reason why it is not yet in Erik's version? EDIT: something like this? #if TEMP_SENSOR_0 != 0 #if TEMP_SENSOR_1 != 0 MENU_ITEM(submenu, MSG_PREHEAT_PLA, lcd_preheat_pla_menu); MENU_ITEM(submenu, MSG_PREHEAT_ABS, lcd_preheat_abs_menu); #else MENU_ITEM(function, MSG_PREHEAT_PLA, lcd_preheat_pla0); MENU_ITEM(function, MSG_PREHEAT_ABS, lcd_preheat_abs0); #endif #endif

Analysis -> Unit/Scale...

I see one problem: TEMP_Sensor_2 is for the third extruder/hotend (it begins with 0)... I think you missed to delete the old menu entries... the two lines which should replaced with exactly the part with the IF section... About the buzzer sound: you can adjust it with LCD_FEEDBACK_FREQUENCY_HZ and LCD_FEEDBACK_FREQUENCY_DURATION_MS in configuration.h...

Hi drayson If I got you right, this is what you did: you downloaded the Marlin code (from which repository? ErikZalm or D-Link?), adjusted the settings in configuration.h, made some changes in ultralcd.cpp compiled it with the Arduino tool or another C++ compiler and uploaded it to the machine. Correct? Or did you use the marlinbuilder? About the Ulticontroller-sound: There is http://umforum.ultimaker.com/index.php?/topic/4543-switching-the-ulticontroller-sound-off-any-ideas/ right now where some people complain about the originally very loud sound. Different people - different meanings...
