You changed something else than just "104gt for ext0 and 100k epcos for bed", the firmware you posted does not match these settings. Well if it worked 30 seconds, it means that the build generated valid Arduino code, so the builder itself is not broken. It remains 2 possibilities: Marlin is broken for your selection. I am skeptical, but there is always a possibility. However I can't investigate that until I know exactly which options have been used in the builder There is something wrong with your hardware setup (obviously neither the hotend nor the bed are standard Ultimaker components and they both require changes to your electronics) 1 more thing i ve chosen was 500ms pwm. Right now i couldn't receive my arduino and made this setting 200ms, now everything works find.

The problem was with old firmware!

Only sensor to 104GT, and baud rate to 115200. Nothing else. First unresponsive board was to 104GT and sensor for heated bed + 225000 baud rate (I thought that baud rate caused that I cannot upload firmware either through Cura or Arduino IDE). I mean Arduino Mega 2560 (pretty much regular arduino board). After disconnecting original Arduino Mega board I wasn't able to upload anything (timeout) Cura / Arduino IDE. Same happened with second board (original Arduino Mega 2560). I have uploaded other firmware (Cura/Arduino IDE) before this one and had no issues. After I've uploaded a firmware from this site for Ultimaker, Arduino Mega is dead, unresponsive and can't install any firmware (even just few lines of random code, just to clean it out) I got the same problem, but i found the solution! 1) take the arduino off the ultimaker pcb 2) turn off usb from arduino 3) take jumper and place it on the right (lighted it) 4) open arduino with ready to upload scheme 5) connect arduino to usb and upload firmware as fast as you can if fails try to hold reset button and turn off and turn on the jumper ( with usb ) At 3rd attempt my arduino work nice now!

This is build that i installed. It worked for about 30 seconds. Then arduino became warm and now i cant upload nothing to it. this is build that i installed. http://dropmefiles.com/vUGUW

I've got the same problem.... I made a firmware with 104gt for ext0 and 100k epcos for bed and now i cant connect to 3d printer with any tool and can't update the firmware...

Hello everyone! I have a problem with my ultimaker original. There is an error. [ERROR] Error:0: Extruder switched off. MAXTEMP triggered !Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting) If i connect UO electronics without any wire connected, should it give me this error? Sorry for my bad English. Thank you!

Maybe someone has an UMO? Really need this, because my pcb lies near printer...

Yes! and another one is a little bit longer. Can you help me to find it?

i'm not sure this will fit ultimaker original... They are like a nuts.

Sorry, can't open this page(( http://prntscr.com/8sq8zr I need them to hold on electronics on ultimaker original

Hello everyone, i have a problem. I lost my threaded spacers. Can someone tell me the exact size of them? these white things i'm talking about.

Hi there, is there any way to help you to translate cura to Russian for example? I will do it myself for free, only mention my name. If you need such a help, let me know. TY

I think that problem is with your feeder stepper driver, try to increase voltage a bit, and loose your feeder screw. As for me, my ABS settings are - 250 temp, 100 HB, 0.1-0.15 layer height ( more than 0.15 my ultimaker feeder stop working on 4th layer.

Hi there guys , I had a trouble, my z axis started to miss some steps when going up. Tried to increase voltage on stepper driver, lubricated the 2 z rods. But it still miss, thx for your help!

So the problem was that filament just couldnt het through the tube to the hotend, because of bad tube positioning and i forgot to use blue clamp. Now its okay, but ive broke my thermistor . Can i connect k type thermocouple without dissoldering 4.7k resistor?
