Hi Daid, honestly, I don´t think it "sucks" - I get good results if putting in the right settings. Nevertheless, from my point of view, due to the extensive testing and development of you and your team, I´m sure you will build one of the best versions ever... :smile: RC6 seems to work also in my strage SW environment at my office notebook without issues... Update: At my private notebook, when switching into layer view, I get an phyton error and the program shuts down... :-( Yipeee.... :-)

Hi Daid, installed R6 and tested the support structures - it seems that there is still a bug in the X/Y distance setting. Setting it to 0,7mm (default) gives nearly no support so printing mid air is the result. Setting it to 1.0 or more, it gives a good value and no mid-air printing. Here the screenshots: I can remember that such behavior was also reported a while ago (but not sure if in this thread or related to this release). Nevertheless, thank you for your great work !!

Thank you, I will add it of course with reference to you.

Hi! Great adaption! I have not mounted my heater pad yet so I had no chance to check the bendig behavior of my original cables - just tested it with some other cables and there it worked. Would be great if you could also publish this modified part. :-)

Seems that the dual extruder topics might come up now again... That´s a great idea if it could be done this way... and without extensice efforts...

Really??? I have not recognized this... My experiance is that I adjusted inpropper flow via setting a much smaller diameter on the second nozzle - and I got better results in dual print... Independent settings would be really necessary - also for E-Steps and flow.

If you just want to extrude the main part @ nozzle1 while the support structure is printed @ nozzle2, cura is able to manage it. I have V14.1 installed and it works. If you are looking for another application it would be good to know the use case first. B.t.w. - my intension is to print PVA on the second nozzle as soluable support... Same idea?

Oh yes, I support this... inner islands of the skirt are horrible when printing parts with smaller holes in it but I like skirts for priming therfore swich off is no "real" solution...

I read a post on this topic a while ago - don´t know if you mean this, but take a look here: http://umforum.ultimaker.com/index.php?/topic/3590-individual-use-of-dual-extruders/&do=findComment&comment=27680 If you try, please post your experiance as I also started using my second nozzle a week ago...

Ok - I also found the corresponding posts. I will have to consider this, when finally setup the HB. Thank you for your hint!

Thats an important info as I have not remembered/recognized this behavior and I'd like to get my HB working soon. Workarounds are always a second hand solution so hopefully there will be enough attention on this topic. Is there a way to switch the heating sequence in the FW permanently?

Thats a great idea! I have my HB-parts already at my desktop, PSU is missing so I have to update mine soon. Would you share your code?? Would be great if I could use it at my machine too... :-) Thank you in advance!

Looking at your designs Sigi let me think that I also should start producing.... a son :smile: Otherwhise I can´t explain why printing toys... That´s one of the best examples for usefull useage of a "men´s toy" as my girlfried always name it. Imagine, how expensive such nice toys are in the shop... "Honey, we saved money..." Congratulation to your designs!

I agree... Unfortunately I had no time up to now to give your code a test. Hopefully over the weekend. Nevertheless, I hope that this feature will be implemented in the standard Marlin soon... :-)

Hi! Does the extruder itself stop moving or is it a matter of not moving filament? How old is the filament? Have you tried other ones? You could try to heat the nozzle and tell the extruder via print window or UC to move a few mm - what happens?

Me too - therefore I recently built it myself... 18V relais, silicon heater, alu plate, glass plate, PSU??? :-)

Great!! I will also implement that in my version :-) Do you think somebody uses Temp2 instead of Temp1 when only having 2 extruders? It might be an issue for non-UM machines but as far as I recognized, more than 2 extruders on an UM are impossible due to missing Polulu contacts on the PCB - isnt? B.t.w. - I managed to get my second extruer working sucessfully !!!

Great, I will also try to investigate but as I have basically no knowledge about programming, I don´t know if it will be successfull... @ extruder - nope, guess, staying cold could effect the lifetime... If you find a solution, weould be glad to act as a "trial bunny" (hope you know what I mean... :mrgreen:)

Hi, your attempt seems to work for a dual head :-) Yeppeeee... Compiled it also for a single head - just to test. Unfortunately it failed due to not declared scope (!?!) (lcd_preheat_pla1). Nevertheless, for the moment it´s fine the way it is. Now I can setup my secodn head...

Hmm... might be a reason. Else, looking a few lines above at the temperature settings, it looks similar to the initial code... #if TEMP_SENSOR_1 != 0 MENU_ITEM_EDIT(int3, MSG_NOZZLE1, &target_temperature[1], 0, HEATER_1_MAXTEMP - 15); #endif #if TEMP_SENSOR_2 != 0 MENU_ITEM_EDIT(int3, MSG_NOZZLE2, &target_temperature[2], 0, HEATER_2_MAXTEMP - 15); #endif #if TEMP_SENSOR_BED != 0 MENU_ITEM_EDIT(int3, MSG_BED, &target_temperature_bed, 0, BED_MAXTEMP - 15); #endif Nevertheless, I will give it a try when back home and in front of the UM...

I found the particular code I mentioned... #if TEMP_SENSOR_0 != 0 MENU_ITEM(function, MSG_PREHEAT_PLA, lcd_preheat_pla0); MENU_ITEM(function, MSG_PREHEAT_ABS, lcd_preheat_abs0); #endif #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); #endif For me, it seems that the "else" is missing... so if there is one snesor, display lcd_preheat_pla0 and lcd_preheat_abs0 if there is the second sensor, display the menu additionally... Or am I wrong??

Sorry, you´re right - as mentioned, it´s just what I remembered by heart. I will check when back in front of the file. Thank you for the buzzer hint !

Hi!! Please find my answers below... :-) downloaded the Marlin code: yes, UM original fork adjusted the settings in configuration.h: yes, acc to the infos from this forum and in comparison with a version from marlinbuilder made some changes in ultralcd.cpp: yes, winmerged the changes Arne did compiled it with the Arduino: yes, V.0023 uploaded it to the machine: yes :smile: Or did you use the marlinbuilder?: partially, for comparison @Ulticontroller-sound: true, different people, different meanings... :smile: Maybe someday this can be customized via configuration.h too... Basically, the builds worked. I made an addon to the FW-version so that I can check it via ulticontroller. Looking into the code, I found that there is an IF section comparing the TEMP_Sensor_2 - if it is !=0 (I assume "not zero"), then it should display the menue, else the normal view (I´m not in front of it so that´s what I remember by hart from yesterday).

Hi guys, as I´m "alone at home" I took a few minutes to try to compile the FW by myself... honestly... not the right work for a mechanical guy... :smile: The implementation of the two menues worked...partially... When uploading, I expect due to the settings that only the PLA and ABS menues are displayed. Instead, I get the following: ... Preheat PLA Preheat ABS Preheat PLA => (menue) Preheat ABS => (menue) ... Further I recognized that uploading the new FW will not reset my changed settings e.g. for z-axis acceleration. Is there a bug or just an "error80"-issue... Another thing I recognized is, that moving the extruder via the move-menue has no affect - not with the original, nor with a version from ginges builder (b.t.w. - the implemented tiny beep sucks) nor with my compiled FW. Any hints appreciated...

Guys, its great to have you all here helping and assisting - and make fun :-) Thanks everybody, you deserve it (and yes, Ian, the statistics shows :-) ) PS: now, I also like to get also a like *LOL* PPS: good night johnboy... :-) damn waltons...
