[Printhead freezing at random]

Hi Bandy, thanks for the information.

 

Could you kindly share the procedure for this  'firmware recovery flash'? I updated the firmware via USB this morning, but it still end up freezing halfway through an 80 minutes print  (the printer was already installed with the latest firmware).

 

Elsewhere I only found the procedure for recovering a bricked UM3, but I probably want to find out more before opening up the machine. 

 

I do not think it is bad power supply though. I had swapped the power outlet and adapter of this printer with that of another one that is working fine. The printer still froze.

Hello,

I'm looking for some help/advice. When using my UM3 the printhead just stops moving in the middle of a print job. The fans on the printhead stay on, the head keeps it's temperature, motors still on, but no movent. The display is still responsive, I can navigate and choose pause/tune/abort, however the hardware does not move. I currently do a reboot to get the printer to initial state.

 

I'm having the problem since a long time (1 year), but I always restarted the job, now I want more reliability to do longer print jobs.

It happens quite often, but since I'm an 'occasional' user, I lived with the issue. If I remember correctly, the issue started after a major Cura and firmware update (at that time I didn't realise it would be a repeatable long-lasting problem)

Printer firmware: 4.3.3.20180529

 

any help/ideas? somebody with similar issues? (Also, is there official support from ultimaker? or only community?)

 

Hi, I will like to ask is there any updates in the aforementioned issues? 

 

One of the UM3 in our workshop has been experiencing the exactly same issues described above for the past ~1.5 yrs. We had sent it to the reseller for servicing twice but still the issues persist. 

 

Initially it really didn't bother us that much as the freezing was rather infrequent. Then it got so bad until the machine just freezes at the "Ultimaker" screen. That's when we sent it for servicing the first time. The reseller flashed the drive and it got back to working condition for a while before the issues surfaced again. Once again, it didn't bother us until it started to freeze on every print job. That's when we sent it for servicing the second time.

 

On both occasions when we sent it for servicing with the reseller, the reseller told us it's an issue with the "motherboard" (main board). On the second occasion, the reseller replaced the main board with a used one which, beside having a faulty power switch, was otherwise in good condition. The printer worked well for about a week before the freezing issue returned again. This is the current situation now.

 

We are now hesitant to contact the reseller, who would most likely advise us to purchase a new main board. We really do not think getting a new main board will solve the issue. Therefore, anyone who can offer any help/suggestion? Greatly appreciate it.
