I've gone through lots of debugging scenarios for this and I'm hoping someone can help pinpoint how to fix this. Running a UM3E 5.3.1 with Cura 4.11. The tl;dr is active leveling constantly fails before a print, but I also can't turn it off because the z offset is not being stored or remembered with the printer. Scenario 1: Active levelling fails when set to "Always" before a print. Error of unrealistic value between print cores. However, active levelling can be performed as normal through the build plate menu. Scenario 2: Active levelling is set to "Never". Set manual levelling, perform active leveling. Print 1 prints sucessfully. Print 2 - same print, same settings, same everything - fails because the nozzle is trying to print about 2-3mm above where it should. Scenario 3: Active levelling set to never. Perform manual levelling. Did not perform active levelling. Print fails because print head is 2-3mm above the configured z offset. What do I do? This seems to be some sort of firmware issue because active leveling works 100% of the time form the build plate menu and 0% of the time before a print. And I can't turn the whole thing off because the z offset never gets set correctly with manual levelling.

Just adding I've had nothing but problems with the latest firmware version on my UM3E. I have a UM3 thats running just fine. * Active leveling constantly can't be performed * Can't even turn off active leveling because the manual leveling values don't store correctly * Prints stopping mid-print, the timer still remains but the print head is frozen I've been fighting with my UM3E for weeks now and I'm ready to throw it into the sun. Wholly disappointed in the lifespan of this printer.

This issue still persists in 5.2.18. After upgrading both my UM3 and UM3E, the UM3E started exhibiting this exact behaviour although the UM3 did not. After performing manual levelling and running the active levelling procedure, Print core 2 would print WAY too close to the bed. Was pulling my hair out trying to troubleshoot thinking it was a mechanical issue. Also tried swithcing print cores for both slots (all stock) and the issue persisted. After finding this thread and setting active levelling to "Always" (it was previously set to once a week), I could resume printing with active levelling calibrating the values correctly. These are the steps that introduced the issue on my UM3 Extended (again did not apply to my UM3) 1) Perform manual levelling 2) Run active levelling from the build plate menu 3) Try to print with print core 2 -- core 2 is too close to the bed ^ worth noting I repeated the above steps multiple times for troubleshooting so maybe an error was introduced due to redundancy

Hi, I attached the log file in the first post.

Well this is a bummer. I successfully went through the steps of doing firmware recovery with the 5.2.16 recovery image via Olimex board and the issue persisted on the first print. Video of the behaviour: https://www.dropbox.com/s/qqcjvb8ktkdjr33/IMG_3383.MOV?dl=0 I didn't update the firmware to 5.2.18 after the recovery. Printer just freezes, timer still going and when I tried to pause it it gave me a "detected move outside of normal printer volume" error. I've been printing this same file with the same settings for months back to back and it was only after I installed the latest firmware did I get this issue.

Have a UM3 Extended which has been operating with no issues. After updating to the latest firmware, I've tried to run about a dozen prints and each time they fail silently or with a z switch or travel move error. I've tried reinstalling the firmware via USB and the issue persists. About 5 times in a row now the printer silent fails, with no error on the display and the printhead just stick mid print. I've also tried resetting all digital factory settings and the issue persists. Can someone please assist on what to do? I run a store and being down a printer is costing me money by the day. Attached the most recent log. dmesg.log

@ctbeke I'm having the same problem with both my UM3 and UM3E. Trying to troubleshoot the UM3 now. Did a factory reset. Connected to wifi. Will not connect to digital factory at all. I've attached the log files. I've also tried connecting via my phone and browser, neither work. UM3 log.zip

@nallath This is incorrect. I have specifically set up the printers to NOT be in a group, however there seems to be a bug where it thinks it's in a group. I had to ungroup them because it seems the "Select printer" option has been disabled in 4.9. For example, look at the below screenshots. Noah (the UM3) is the selected printer. But it's displaying as the UM3E. When I print over network, it gets sent to the UM3E and not the UM3.

I have two Ultimakers, a UM3 and UM3 Extended. Trying to managing printing to both from Cura 4.9 is riddled with bugs and there seems to be a new one every day. UM3 = Noah UM3E = LongBoi I'm trying to send a file directly to Noah. That printer is active in Cura, but when I print over network it keeps sending files to LongBoi. I've turned everything off and on again multiple times but this keeps happening. Noah says waiting to print, no print jobs, and the file I want to send to it keeps getting queued with LongBoi. Any advice on how to manage a dual UM workflow without grouping them? I have different filaments and settings for each printer, they need to be managed seperately.

@nallath I have tried doing that, though it keeps trying to put the printer in a group. All day yesterday I could toggle between the two, then just now I tried to print and it said I couldn't send something directly to LongBoi because it's not configured as part of a group. Really inconsistent behaviour. I've already set up each printer individually, twice. Per the screenshots below it keeps shoving LongBoi into a group which is super frustrating since it's random if I can print to it or not.

I own two UM3's, normal and extended. I rely on being able to select the specific printer I send my files to since each runs different filaments. Now in 4.9, I cannot choose which printer to send the file to. The selection is disabled for anything besides "Automatic". Worse, I can't seem to target a specific printer from the web manager. Help? How am I supposed to manage targeting a specific printer? I had to spend hours connecting and disconnecting printers to get this workflow figured out in the first place, it's very unintuitive. Cura and digital factory are always yelling with notifications that groups aren't supported anymore, then I'm forced to make a group to target a specific printer, now I can't even do that anymore. Was planning on buying two more UMs by the end of the year but if this basic feature can't be sorted in a somewhat intuitive way I'm not sure how to move forward.
