Oke, that sounds plausible! thank you very much for your time and effort! If I'm correct the heater cartridge is 18V right? I will order a new heater cartridge and see if it will work again. I will let you now if it works!

I measured the resistance of the heater cartridge (the two wite insulated wires) and it is 0.03 ohm. When I disconnected the heater cartridge and wanted to preheat the printer the temperature setting went up and nothing happened as expected indeed. I hope this helps.

I didn't think about that indeed. Thanks for your help, I will keep you updated!

Yes, it is definitely an 'old' printer and it has worked fine for me the last couple of years without any major problem. But after finishing a print I wanted to preheat for another print and suddenly the printer shuts off. I didn't do to, or modify anything on the printer. Personally I don't think it's a power supply issue since the printer can be switched on, the problem occurs when I want to increase the temperature. This afternoon I will measure the resistance in the heater cartridge, do you have any expierence with that? Can you suggest me some cables/connectors that I should measure? Thanks for your suggestion!

I have a UMO, without heated bed. With the preheating I'm referring to the option preheat PLA/ABS. Basically to warm up the printer. As I mentioned in my previous post it also happens during manually warming up so to me it seems like sort of a protection which the_shire suggested.

Thanks for your response. No, everything is original and i didn't add anything. I also think it is going into some kind of protection. Today I also tried to manually heat the printer but that also doesn't help. Do you have any suggestions regarding the over current protection? Thanks in advance.

Hi, When I want to preheat my Ultimaker Original the complete system shuts off. The display turns off and I have to wait a couple of minutes before I can turn it on again. Does anyone have an idea why this happens? Thanks in advance! Tom

Thanks for the reply's! I also submitted a ticket and it all will be arranged, I will receive new X, and Y - motors from Ultimaker. Cheers!

Dear all, I have a question relating the X, and Y - motor. I think I received two wrong motors with my Ultimaker Original kit. All the motors with the long wires have a flattened axis (see the attached pictures). Does anyone of you know if I can still use them as X, and Y- motors or should I really have the round axis instead? If the latter is the case does anyone have a suggestion with which step I can continue my build? That would be really helpful!
