I've recently started using Fusion 360 and I'm wondering about the "Mesh Refinement" setting when I'm exporting a file for printing through Cura on a UM3. Under the "Save as Mesh" command, I select STL and Millimeters and then there's several "Refinement" settings. There's the basic HIGH, MEDIUM, and LOW setting, plus a CUSTOM setting which lets you adjust 4 different "Refinement Options". Does anyone have any understanding and or suggestions as to how these settings affect Cura and the finished 3D print? Thanks for your help.

I updated to Cura 4.11 and it's working fine now. 😀 So... "Never mind."

This just started after I updated my UM3 with the latest Firmware Ver. 5.2.18.20210820 In Cura, the Monitor Tab does not update when a job is running or when it finishes. It shows 9% complete all the time even when the job finishes. When I start a new job it updates to show the new part but still shows 9% complete. I'm running Cura Ver.4.10 on a Mac running OS Ver. 11.5.2 and communicating to my UM3 via WiFi. Not that big of a deal. I can look at the status on the web page, but it's kinda odd. Am I doing something wrong?

I think you nailed it! That fan has a broken wire. Thanks for your help.

I have a UM3. It all started with a big print fail, The Material backed upped into the head and in the process of trying to clean it up, I damaged the head. Fortunately, I had a spare AA 0.4 head. I installed the new head, loaded PLA and, as expected, it wanted to calibrate XY. When it printed the test pattern the Y outline looked OK but then it started printing dots. Kind of like the head wasn't getting fed enough material. I have unloaded / loaded material and tried to calibrate numerous times and it does the exact same thing. I tried cleaning the head and the feeder and still get the same result. Immediately after loading, it starts out OK but, within a few minutes, it starts laying down dots. Another symptom I've found is that when loading material, it starts out coming through the head good but if I don't hit "Confirm" and let it run, the material will start coming out slower and slower. Eventually, the feeder puts a notch in the material and won't feed anymore. I tried increasing the pressure on the feeder spring but that didn't seem to do anything. I have tried 2 different heads with the same results. I have watched the temperature graph and the head appears to be holding the correct temperature. I've run out of things to try. Thanks for being patient enough to read all this, If you have any ideas...

I am having trouble connecting my UM3 to my WiFi. I go to Systems>Network>Run WiFi Setup and it creates a WiFi Network. I connect to the created network on my phone or computer and click "Start WiFi Setup". I name the printer "UM3-5" , then select the my local WiFi network and enter the WiFi password. The UM3 reports "Connected". WiFi is selected on the Network Menu. Now I go to Cura and try to Add the Printer. Today it can't seem to find the UM3 when I click refresh. Other days it works? Even when it's working, it seems that when I leave it off for a few days I must go through this hit or miss process of resetting up WiFi. What am I doing wrong?

Is this still available?

I ask because this is the first Ultimaker material that I have bought that didn't include a resealable bag in the box. Thanks for your assistance.

Thanks so much Smithy.

I'm interested. Do you have the boxes that it came in or how would you pack it for shipping to Texas? How do I contact you?

Are the print heads used on the S5 identical to what is used on the UM3. I'm upgrading from a UM3 and wondering if the printhead selection I have will work on the S5?

Thank you so much! That was a great help. I went so far as to remove the heated bed and no brown wires there. Also looked at the PCB. I didn't take the board out to look at the back side but I don't see any toasted components, PCB, or brown wires there either. I wiggled all the connections and cleaned every thing (it needed it.) After re-leveling the build plate, I tried printing again and it worked this time. (Yea!) I don't know what's going on but I guess I'll just keep an eye on it unless you have another idea I should check. Again, thanks so much for your help!

Wow and oh c__p! Thanks for letting me know. I’ll look into it. You don’t happen to know where I might find some instructions or diagrams as to how to take the printer apart? Thanks again!

I have a UM3 and I'm trying to print with CPE+. Cura defaults the Build Plate Temperature to 107, but with the bed heater set to max (255) the plate never quite reaches 107. Looks like around 104. So the printing never starts? Any idea what's going on? It did work 2 days ago.

The "Custom Printjob Naming" plugin does do the trick. I can't select an object, I open the "Custom Printjob Naming" plugin dialog box, click "Cancel", and then I can select objects. Maybe that info will help the developers?

That's interesting... you're "open a plugin dialog box" work around does not work for me. The only plugin I have is Auto Orientate. Maybe you have a plugin that does something different?

Giving Cura "Full Disk Access" did not solve the problem for me. I find it interesting that it seems to have worked for at least 2 people.

I have done 5 prints since I followed Smithy's recommendation and raised the bed slightly. It appears to have solved the problem. Thanks Smithy!

I ran Maintenance>Diagnostics>Bed Level Sensor 5 times and each time it says "Sensor Performance is good". I then turned all 3 screws and raised the bed slightly and did a manual bed leveling. I then ran the active level process 3 times with success. Now, back to printing and we will see what happens. Thanks for your help.

I frequently get an Auto Leveling failure at the start of the print. I find I can fix it by taking an x-acto knife and scraping a little blob of material off the nozzle tip. I'm wondering if anyone / everyone else deals with this minor but annoying issue? It seems that the material is not retracted quite enough and then a little oozes out on to the tip and then hardens. It makes sense that the auto level would fail with that blob on the tip. Thanks for your insight.

Thanks for your efforts. At least I'm not to blame! Usually it's me doing something wrong. 🙂 Hopefully they will be able to quickly find the problem.

Well that’s encouraging. At least it’s not just a me problem. Thanks for your efforts in reproducing it.

It's not consistent, but after loading a simple model, if I repeat Rotate, Move, Slice, Monitor, Preview, Prepare it will stop allowing me to select the model after a few loops. I did this 3 times in about 5 minutes.

I do have a 3DConnexion Mouse! How'd you know? It seems that if I piddle with Cura long enough it always happens.

I'm running Cura 4.8 on a Mac with Big Sur Ver 11.0.1. When I first start Cura, all is well. (Works as expected) Typically, the problem appears after I print a part and then load a new part to be printed. I cannot select any parts. If I close Cura and restart, I'm back to normal for a while. It happens as described but it has happened at other times too. Cura is not locked up because I can right click and the menu drops down. This is annoying! Any help would be greatly appreciated.
