Hello, again to return to the topic, here it is not a real case, even if the question is worded as if someone needs help. I have therefore als the topic only as a request for dicussion. This is of course a technically possible solution has to be taken into consideration. For who is because even his UMO+, just because a driver is defective, his UMO+ such piles. Because it would be an easy to obtain a new driver and have to replaced. This would however is much cheapter and with less work. If I only think that all of the connection cable to the connector board with new cells(plugs) must be assigned to which can still be ordered from the Far East, because otherwise it will be on the market. In addition a second power supply, as well as thermo sensors , I do not know, but from the economic perspective, it would be simply can not be represented. We will continue with this board installation even an outsider, which in the event of a fault, hardly anyone can help because the beautiful interior life of his UMO+ total mess up. By the time not inconsiderable time not to mention, because it was the simple change of driver in the question above, yes no role at all. My mind is that it would already be feasible, but wheter it is worth is gone. Without doubt has such a GT2560 also has its benefits, probably more on any 3d-printer as a ultimaker I since the Member Amedee and say: I do not know if I have my UM in which only one driver is gone, would do. But it is still interesting to me when I have a blank UMO or UMO+ (total without electronics), then I would also install a GT2560. But when is one had already been an emty Ultimaker. Greetings to all, Conni

Hello to the unknown seeking help, I have now once again all possiblities into consideration and come to the decision that GT2560 only in a UMO can be implemented, but even then the temperature sensors hat to be replaced, the UMO are thermo couple(TC ad595 or 597) installed, which must be exchanged against PT100K, so that it corresponds to the GT2560. Then it should work and it can definitely an additional extruder and a heating bed with operate. Provided it is the appropiate power supply avaiable. But to the Marlin firmware on the GT2560 to get, since you have some tricks. Because it does not simply, via the USB connector on the Board, the Marlin firmware over, because here must send an ASP/ISP. But this must have been previously prepared for this pupose. Because there are on the GT2560 no official slot. It must be on each of the pins of the SD-Card-Slot is improvised. In the case of interest like like the pin-layout publish it. Therefore als a UMO+ should operate with the GT2560, but board moderately, it would be a step back to the old UMO-board, only walk with the possibilites for 2. Extruder and heating bed, but even here the temperature sensors and replace the GT2560 appropiate power supply. So it should in the theory for Hardware, it only remains to how do you get the Marlin firmware on the GT2560. But as already announced that there is an ASP/ISP-solution.

Hello amedee, thank you for your feedback. Because of the temperature sensors, i have my post edited. I also think that it will be difficult, but there should be a test value. It ist not my UMO+, but he belongs to the writer (the man needs help or the man of Help), which this thread has started. I am a 73 year old pensioner and I bought a used UMO. I will now "bring to front man" ( a german saying), that is either set or modify something correctly. A heated bed is not excluded, but he is still on the way to me, so I am waiting time as I the thing to run(print) would bring. So now I wish you and all our readers a Happy Printing. Greetings, Conni

Hello SandervG, thank you for the nice post. Would like to quickly make the translations to enable all readers understand. I hope the automatic translation makes it almost correct. I have written in German the following: Hello, i prefer to write in German, since I can better. Unfortunately, thr unknow reader now with the translation effort. If Ardino IDE has checked the program and it is uploaded to the board, then you can still somewhat in the program is not correct and it results in a different pinout etc ... Is to ensure that the power supply is working and that the correct voltage arrives on the board. Are the fuses in order ? The board has two separate power inputs. Both are connected correctly ? Even if the Hardware everything ok, then there is still some software problems. Because ultimaker is not equal ultimaker, because there are some things that are in the Marlin firmware must be defined accordingly. For example: Which number was after #define Board __ be used ? I am first circuit and wait for more information. (I think of those seeking help.) Greetings to all readers Conni PS. Sorry for the poor, perhaps, English, in this and the prvious post, lent it is the free I-Net translator.

I am again, I have a free internet translaters are selected and my idea again refreshed. Thank you for the welcome. Now to the problem. Hello, you have now a UMO+ with one geeetech main/motherboard GT2560. In the UMO+ was previously a UM-Board V2.1.1_(x1), for Marlin must now be informed in wich board is used. As the first of the processor is selected, here ATmega 2560, then for general ultimaker is the index 7, otherwise 71 or 72. For example: #define BOARD_ULTIMAKER 7 or #define BOARD_ULTIMAKER_OLD 71 (old electr. 1.5.4 etc..) or #define BOARD_ULTIMAIN_2 72 (use TEMP_SENSOR 20) In addition to Marlin is written: #elif THERMISTOR_ID == 20 #define THERMISTOR_NAME "PT100 UltiMB" (I think it means PT100B) GT2560 recommend Temp_sensor 100K, but UMO+ and UM2 the PT100B, the last then corresponds to a ultimainboard V2.x, which is before in the UMO+ was installed. My knowledge, can a GT2560 but only ramps 1.4 with arduino 2560 or the older ultimakerboard with the arduino2560 replacement. Whether it is the ultimainboard V2.1 replaced, that will now. Have fun to try. Greeting, Conni

Hallo, ich schreibe lieber in Deutsch, da kann ich mich besser ausdrücken. Leider muß sich der unbekannte Leser nun mit der Übersetzung bemühen. Wenn Arduino IDE das Programm überprüft hat und es ist auf das Board hochgeladen, dann kann immer noch etwas im Programm nicht in Ordnung sein und es ergibt sich eine andere Pin-Belegung etc .... Ist sichergestellt, daß die Stromversorgung funktioniert und die richtige Spannung auf dem Board ankommt. Sind die Sicherungen in Ordnung ? Das Board hat zwei getrennte Strom-Eingänge. Sind beide richtig angeschlossen ? Selbst wenn mit der Hardware alles in Ordnung ist, dann kann es noch einige Software-Problem geben. Denn Ultimaker ist nicht gleich Ultimaker, da gibt es einige Sachen, welche in der Marlin-Firmware entsprechend definiert werden müssen. Zum Beispiel: Welche Kennzahl wurde hinter #define MOTHERBOARD __ eingesetzt ? Funktioniert denn wenigstents die LCD-Anzeige des Ulti-Controllers ? Ich mache hier erstmal Schluß und warte auf weitere Informationen. Grüsse an alle Leser Conni
