Screen/Input Freezing But Still Printing

Recommended Posts

Posted (edited) · Screen/Input Freezing But Still Printing

One of our UM2s started acting up today. The screen will freeze soon after the print starts. The input wheel does nothing but the part is still printing fine. When the part is done printing it will retract a few mm but then stop. The screen is still frozen and the input still doesn't work. I have to power off and restart the printer to get things working again.

Any ideas what might be causing this?

I am having a similar issue with my UM2+ running with the firmware that came with Cura 15.04.4 (will be updating to 15.04.5 once the print finishes). Did you ever figure out a fix for this issue?

Backstory:

I am running a 28-hour print (scaled up version of the included tetra-wire example model), the screen seems to have locked up around 13 hours left with a line through the top line of text (and part of the second line) like a strike-through. There is no response to the control wheel, either rotating or pressing. The print itself however is still chugging along, I just can't tweek any of the print settings on-the-fly now with the UI unresponsive.

Hi,

I'm also seeing this. I upgraded to 14.04.5 and I think I saw the issue then too, but I am not sure becasue I downgraded again on the advice of UM GB support due to a stepper motor issue.

I have seen this issue 3 times now in the last few days. I thought is was due to an overheating main board due to the steppers issue

Did Upgrading to 14.04.5 fix this for you?

Thanks,

Greg

Having the exact same issue. Screen and control knob freeze during print. The print finishes but the print head doesn't retract after finished job. Did a 2.1 firmware upgrade but no changes. Any kind of help considering this issue would be higly appreciated.

Sorry for the late response, I didn't get email notification. I ended up replacing my mainboard, and I also typically now run a separate fan across the underside of my UM2 because there was definite heat-staining on the MB around the stepper controllers. I can't say now whether that was responsible for fixing it, but I haven't seen the issue recently.

My Ultimaker 2+ started showing this exact symptom a couple of weeks ago.  At first I thought it was a firmware problem caused by static discharge, but after reloading the software the problem continued.  I eventually realized the problem occurs only when I put my new thermal cover on the machine for use when printing ABS (which does help the print quality immensely!).  Without the cover on for PLA printing, there was no problem.  

I had a spare Rotron blower that happened to fit under the printer, and blows through the main electronics enclosure.  It has printed several ABS parts for the last 40 hours or so with no further problems, so I think it was heat related and the fan fixed it.

I've got a UM2ext+ and had the same freezes, used tinkergnome 16.08.1 and 16.08.2

Downgraded to tinker 16.03.1 and it never happend again for more than a month now

with several long prints (+ 24H prints )

So i stay on 16.03.1 for now

hey hey, our UM2 has just developed this error. often during a print the screen lock up with a couple of lines through it and the interface will stop working. when this happens the print will still _finish_ but the nozzle never retracts so it just sits melting wherever it stopped.


i’ve updated the firmware (a couple of times) and tried with new SD cards but the issue still occurs, and i haven’t found any useful way of getting data out about how/why.

 

my gut feeling is that it’s a hardware failure somewhere, but, i’m just wondering if anyone has worked out _what_ that is likely to be or been down this path already?

 

it doesn’t seem to be a reset, because you’d expect printing to stop and the ui to function again, so i’m wondering whether it could be a power supply issue / brown-out, but there’s also not much in the way of power circuitry on the board that you’d expect to go wrong and i’d kindof hope the firmware would detect that.

 

i’d much rather repair the existing mainboard than replace it if it’s possible, but, i’m grasping at straws at the moment as to _what_ would cause the problem.

So is this tinkerMarlin that is doing this?  Or Ultimaker Marlin?  This exact problem has been reported quite a bit for tinker Marlin but I"m not too surprised if it's in regular marlin also.

 

I recommend you go to tinkerMarlin version 16.01 and/or if you have tinkerMarlin (any version) it seems to crash less if you turn off "geek mode".

 

https://github.com/TinkerGnome/Ultimaker2Marlin/releases/

 

Scroll to the bottom and hit "next" to find 16.01.  Then click "assets".  16.01 with geek mode off seems to work really well.  Even with geek mode on it seems to crash less than all the newer versions.  There's a long discussion on this topic on github in tinkerMarlin in "issues".

hey thanks for the response!

 

i've been using ultimaker marlin (for it's previously excellent stability) for a couple of years prior to seeing these issues crop up. and i've factory reset and re-flashed the ultimaker version following the issue a bunch of times in the hope it was something weird.


do you think it's worth trying tinkerMarlin 16.01? i'm wondering whether i should revert the stock firmware back to something from 2016.

I recommend 16.01 even though, yes, it's from 2016.  Marlin for UM2 really hasn't changed much since the UM3 came out so 2016 is actually a quite good version.  You can always switch again.

 

A warning about moving *backwards* in versions - always do a factory reset after installing.

interesting, so i actually have a UM2+ (upgraded from UM2) which has the inverted feeder. i see in a bunch of comments you've suggested tinkergnome has an option to toggle axis inversion, but, i can't seem to find it or any reference to where it _should_ be?

(also, do ultimaker make old versions of _their_ firmware available anywhere? it seems like the GitHub repos were never updated and their software download section that's linked from everywhere else is now _gone_)

I have this phenomenon very occasionally in one of my two UM2s, not in the other. There is no clear indication why, although it is most often when playing around with the control-knob a lot. If I don't touch the knob, it doesn't happen. And it gets worse in very dry weather. So I don't know if this is a firmware-bug, electromagnetic spike issue (heater or steppers switching on or off, causing spikes), electrostatic discharge issue (like sparks in freezing weather), communication-issue between knob/display/mainboard, mainboard hardware, or a combination... The randomity makes me think it might be some EMC-issue interfering with the communication between mainboard, knob and display. But this is pure guessing...

It should be in "advanced" "preferences" "motion settings".  Last item in there.

 

I'm not sure if 16.01 has the invert axes, sorry.

I've also had good luck with any of the other versions of tinkerMarlin if I turn off geek mode.
