I don't know of such an option. Perhaps you can try to align to Z, and then repeat 2 more times for all edges? There is a convenient option in the rotate menu where you can select the face to align to the build plate. I just tried and it seems to work.

What Cura version are you using? This might have been fixed in a newer version. If you are willing to share your project we could have a look and see if the issue is reproducable. Also, since you are printing at 'Ultra fine' resolution, you might want to try out the new Cura beta release with Arachne engine. This next generation of Cura will be able to print details better.

Some settings have also been changed to a more reasonable default. Most logical explanation for this big difference though is that you are printing at a different layer height. Perhaps your previous print was at 0.1mm and now at 0.15mm. That would roughly reduce a 6hr print to 4 hours. When you do have the original print file, then you can compare the used slicing settings. At the end of the gcode file the used settings are listed as comments.

I suggest to use the automated pause function over a manual pause, you'll be sitting a long time in front of your printer. Fun to watch, but not efficient. When you don't know the desired height, then it is easiest to set the 'Pause at height' plugin to stop at a 'layer number'. In the Cura preview page you can use the slider on the right to browse through all layers. Both the top and bottom handle of this slider can be dragged individually to change the number of layers shown simultaneously. I often drag these handles close together so they only show 1 layer at a time. Then grab the slider in between those handles and you can view your model 1 layer at a time.

@jeremymorgan @wdwms @DemonicYoshi This forum is for users helping each other. When you want Ultimaker to take action, then use the support link posted by @gr5. By coincidence I see this topic and created a ticket for you guys. Being curious I also had a look into the problem and I think I found the problem. A led driver chip is used for the LEDs in the print cores and a few spare pins are used for controlling the fans. The LED's brightness can be controlled from 0 to 99.6%. The fan function is inverted and ranges from 0.4% to 100%. This means the fans are always a tiny bit on and that might be what creates the noise. I'll test a firmware fix this week. No promise on when it will be released.

I don't understand the question. Perhaps other people do, then they can jump in. But, until those more understanding people join, it would be helpful when you could provide more info. So far I have discovered from your posted files that you have sliced an object for the S5 printer on Cura 4.12.1. This is for the material PLA and you are only using the left extruder. You also posted an obj-file. Many programs use such an extension. For what kind of program is this file used? Blender? Please give more details about your problem. What is happening and how would you like to see this different?

Cura does have this functionality since ancient times... Cura menu Extensions / Post Processing / Modify G-code. Click 'Add a script' and then select the 'Pause at height' script. One known caveat though, the current UM2+C printer v1.5 firmware doesn't support this feature yet, this will come in a future release.

This is weird, you describe different types of problems that I've never seen before in this combination. First try to get your printer to display again by running the recovery process described in this thread. Then, when you run into printing problems again, could you dump the log files to usb and send them to me in a private message (click my avatar and on top of my pesonal screen is a 'message' button). Dumping the log files can be found in the system/diagnostics menu.

Yep, there is an extra motor driver on the UM2(+) pcb for a second extruder that was never used (E2). When you are willing to make some software changes and compile a new firmware version, then you could assign this spare motor driver to the Z-axis. It's a bit of work, but do-able and you'll learn a lot and save some money. The firmware can be found here In the file pins.h at line #1010 you have to modify 3 lines: #define Z_STEP_PIN 37 #define Z_DIR_PIN 39 #define Z_MIN_PIN 30 #define Z_MAX_PIN 32 #define Z_ENABLE_PIN 35 into #define Z_STEP_PIN 49 #define Z_DIR_PIN 47 #define Z_MIN_PIN 30 #define Z_MAX_PIN 32 #define Z_ENABLE_PIN 48 Then compile the code as indicated on the given website and deploy to your printer from either the Arduino environment or from Cura. Other options: In your profile I see you are from The Netherlands. The Ultimaker Mainboard has part number #1546 and can be ordered here, not cheap though at €295 ex. vat. On AliExpress they sell complete UM2 electronics sets for €180, but I can't say anything on quality. Ask for someone with good soldering skills to swap the broken stepper driver chip with the chip from the unused second extruder. It should be someone with experience in repairing smd components, preferably using an infrared rework station.

Cura is a tool for slicing objects and for many printers it can also send the sliced object to the printer. The early Ultimaker models were Arduino based and for those printers a firmware update function is available. Updating firmware can be very different for all printer models and is not the target functionality of Cura. Check the manual of your printer for how to update the firmware, contact your reseller, or check the manufacturer's website.

@polygonfuture Yep, the r1 feeder was updated because brittle materials like PVA got micro cracks in the filament. This can lead to filament breaks where retractions will be ineffective. Not a really big problem for the UM3, just some extra oozing, but in the Material Stations we do many more retracts and broken filament can get stuck at a location where you will have to dismantle the whole Material Station to fix it. That's why for the Material Station people can receive a free replacement feeder, even after the warranty period.

Most likely the problem for the printer rebooting is because the power supply can't deliver enough peak power and the printer reboots on the resulting power dip. That being said, you should try two more things before buying a replacement power supply: When did you last do maintenance on the printer? Dirt and dust on the rods will make it harder for the motors to move, increasing the power consumption. Oiling the rods can reduce peak power consumption by 10 Watts. Never tried myself, but just read a tip for rebooting the power supply: disconnect the power cord, but leave the printer connected and switched on. As mentioned, it could otherwise take days for the power supply to drain. Just some more random tips: Here a link to a topic discussing where to buy these power supplies. And another topic where flickering led lights are recognized as an indication for a power supply going bad. It seems like the Ultimaker spare part is more expensive then when you buy this component from other sources. I see respectable sources for €86 where our American distributor sells it for $185. The power supply is a Mean Well GST220A24-R7B (perhaps your printer has the older, but comparable model GS220A24-R7B (without the 'T')). Get it from a respectable source, not from AliExpress. In Europe I recommend Conrad, but they are out of stock now for 7 weeks.

The S5 isn't an option as it has an internal power supply. Because of the larger build plate, the S5 requires a stronger power supply. The power supply we have on the UM3 is about the largest external power supply available (has to do with safety regulations which don't allow more than 10 amps on these type of connector pins). That's why we had to change to an internal power supply type. The UM2, UM2+, UM3 and the new UM2+Connect all share the same external power supply model.

The printer rebooting is a very rare error. All unhandled software errors result in the printer hanging, not rebooting. Also, many other people use your same 5.3.0 firmware version, which makes me think it's not a software but a hardware problem. The printer heating up the build plate stresses the power supply to its maximum capacity and I suspect the problem is there. Do you have by any chance access to another identical power supply? For example from another UM3 or UM2(+) printer? Then you could swap those for testing. Perhaps you can get a deal from your reseller where you agree on trying a replacement power supply and can return it when no improvement is seen? Perhaps your reseller has a cheap use power supply you can buy? When you are confident with software there is another route you could test: in the firmware we have a setting to reduce the max consumed power. When you reduce that setting it will take longer for your build plate to heat, but at least you can see if this improves behvior without making costs. Put the printer into developer mode (in the System/diagnostics menu) From your computer create an SSH connection to the printer (login with: root/ultimaker) Edit the configuration file with: vi /usr/share/griffin/griffin/machines/um3.json Around line 132 you'll find the setting: "total_power_budget": 221, // [WATT] Change the value 221 to a lower value like 180 (you can start typing values in VI by hitting the 'i' key first) Save results and exit vi by typing: ESC :wq reboot printer and test the new settings Installing new firmware will reset these values again, so a more sustainable solution is to test this and when confirmed to work, then order a replacement power supply.

2. How much are you willing to pay for such a device? My guess is that less than 100 of such units will be sold, so engineering costs will make up the majority of the production costs. Ball park figure for consumer price for a very simple looking device would be around €1000. I doubt Ultimaker will create such a device. My suggestion is to buy multiple spare cores and then use a quiet day to clean the clogged cores in a batch. Cheaper and more flexible than having another tool lying around.

Too bad the UM3 (and S3/S5) doesn't track running hours. What you can check are the running hours for the print cores. Sum all times for the nozzles used in position 1 to get a rough indication of total running time.

Some additional info on the S3/S5 feeders: The S3 and S5 use the same feeders. The feeders for the left and right side are different. Around June 2020 a new feeder revision was introduced: r2 The r2 feeder better handles brittle materials. PVA filament got small cracks and to reduce this the feeder wheel was changed into a finer knurl pattern. The feeder revision code r1/r2 has no relation to the S5 revision code r1/r2 For automatic detection of the different feeder wheels, the electronics was changed Both feeders should be the same revision level, mixing is not supported UM3 firmware v5.3.0 only supports the r1 revision https://support.ultimaker.com/hc/en-us/articles/4408416927122-S-line-feeder-versions I've made a note to support the r2 feeders in a next UM3 release, but no promises here. Ordering codes: 203732 S5 feeder, left, rev.1 203733 S5 feeder, right, rev.1 225720 Feeder assembly left (1), rev.2, fine knurl 225719 Feeder assembly right (2), rev.2, fine knurl 225984 Fine knurl feeder kit (set containing both the left and right fine knurl feeders)

The discussion of the UM3 flow sensor based on S5 feeder has been moved to its own topic:

Just a small note, these configurations are provided by the community, not by Ultimaker. Ultimaker can't test all the hundreds of different printer models. Every user can add new printers, or add improvements to existing printers, on Github.

@varrader Ultimaker made it confusing, but there are two different variants of Digital Factory: the cloud based version and the 'local network' version (previously named Cluster). In Cura, when you sign out of the Digital Factory, you can still access your local network printers. Or, alternatively, use a web browser and surf to the printer's homepage. On the web page of the local printer there is an option for "Set to 'Not available'". This has the same functionality for temporarily stopping the print queue.

@Gero I agree that we can do more in software to resume a print after a power failure, but it's no trivial task. Given that the requested list of new features and bug fixes is large, we have to make decisions on where to put our priorities. Knowing that a cheap UPS will do a better task than whatever we can come up with in software, made us decide to give this feature a low priority. The resume feature might be implemented in a future release, but an UPS of €80 sounds like a more professional solution for a €3000+ printer than any stop gap we could come up with in software.

It must be very frustrating to have such a long print failing on a short power outage. Even a cheap UPS can cover a 10 second power failure without the need for the S5 to stop the print. In Ultimaker we have discussed UPS features several times, but problem is the heated bed. When the heated bed cools down, then even a few degrees of temperature change can cause the object to detach. The heated bed is the largest power consumer in the printer, so when we want to prevent object detachment, then there is little power we can save by shutting down other parts of the printer. Implementing some intelligent communication between printer and UPS didn't seem to add real advantages, other than a check mark in the list of supported features. Best approach seems to be to investigate the quality of the power system in your country and the duration of power outages. Then multiply your maximum power outage time by the approx. 200W consumed by an active printer to determine the required UPS capacity. A high quality brand like APC sells multiple models covering half an hour outage for less than €100.

@CCLMakerSpace You post this in the firmware 6.3.0 topic which is quiet old, stable version is now at 6.5.2. Better is to start a new topic when your subject has such a thin relation to the existing topic. Did you read the help information at the Ultimaker website? ultimaker.com/er86 Especially take note of the last paragraph. There has been a batch of fans with a hardware problem. When your fan's serial number is in the affected range you have to contact your reseller for a (free) replacement fan.

I agree it would be nice for the printer to give priority to a local user, and would only allow remote commands when there was no touchscreen input for 1 or 2 minutes. This feature is still under debate. In Digital Factory you can select 'Disable Printer', this will disable the printer in the DF, including starting new jobs. The printer continues to finish the active job and you can execute all local commands. The queue in DF should restart again when you enable the printer again.

Sounds very similar to another thread: Can you send me all your log files? Send them to me through this forum. Click my avatar, and then on my personal page you see a 'message' button on top of the page.
