Ultimaker original software crash when heating

Recommended Posts

Posted · Ultimaker original software crash when heating

I have an upgraded Ultimaker original - it has the addon controller with SDcard reader.


Though it can still print the UM 'crashes' when heating prior to printing - the controller screen blanks to a low flickering blue.

This problem only occurs when heating up prior to beginning a print.  I need to power it off and begin pre-heating PLA again until I get it up to temperature.

Sometimes it will take 4-6 power on/power off/power on cycles to get the head up to print temp.


Once the device is up to temp it can maintain it and print without stopping.  Even long jobs seem to be no problem.


I've tried most of the usual things I think to fix this.  Reinstalled the firmware (some version of Marlin - not the latest, which IIRC had problems) plus a lot of physically jiggery-pokery such as disconnecting all the cables, removing the motherboard reconnecting everything, looking for signs of poor connections and such.  I've also reconnected the power cables to the print head.

Thinking that it might be power supply related I've measured the output of the power supply and tested continuity of the power supply connectors - all appear sound and supply is of required current etc.


It seems the problem must be some physical sensor or failure such insufficient power to the mainboard when heating is in progress causing the system to crash - otherwise I would experience the crash when printing or at other times when the print head is not being heated - and that isn't happening.


I suppose the next step is to replace the power supply.  Any other suggestions most welcome.

Attached is a pic of my UM original doing good work beside me as I type this.

I should also add that I've tried removing the controller and printing via USB connection to my computer with CURA - the same problem during heating cycles occurs.
