UM2 - motors not working

Posted · UM2 - motors not working

Hi,

one of the cable of my Hot-End cooling fan broke and possibly caused a short circuit.

I replaced the Hot-End cooling fan by a new one.

When I start my UM2 the display works normally, and I'm able to heatup the nozzle (and the Hot-End cooling fan is also working again).

But no motors are working. I'm not able to "Move Material", lower/raise the building plate or home the head. (All tested in the Maintenance menu of the printer).

The error's displayed vary between "Z switch stuck" and "X or Y Switch broken".

 

I already checked the standard things of those errors:

- checked that nothing is blocking the switches (e.g. stuck filament).

- checked that the switches still click when activating them.

- checked the connections at the mainboard (actually unplugged and plugged all connections).

 

I checked the safety jumpers (J16 & J17). When I unplug them there is eighter a specific error message displayed, or the display doesn't light up at all. So them seem to work both.

 

In another thread I read that possibly the relay K1 (24V?), could be broken. But in that case heating up the nozzle should also not work, correct?

 

Anyone knows what could be the issue or how to narrow it further down?

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
