  1. This never was fixed. They "updated" our firmware to a mess and left it. Active leveling is a train wreck and has been for a year. I went in another direction with a few different other printer manufacturers instead of yelling at clouds about this.
  2. This is usually a print cable issue where it loses connection between the print head and the control board. You can try reseating the print head cable.
  3. But it seems like Cura wants to pull in certain Digital Factory settings. It is also duplicating each normally connected printer as a "cloud" printer as well so my list essentially has a full set of duplicates. Some features (camera) are available on the cloud if the "cloud version" is selected, yet you can't tell which on is a "normal connected" printer and which one is a "cloud" printer until you select it and then see the tiny blue and white icon at the corner of the name. I think I will be dropping Digital Factory asap.
  4. I have been using UM3s since 2018 and I liked how Cura worked, I liked the groups, I liked seeing all the printers in on spot with all the jobs printing and those waiting to be printed. Now it seems like half of that has been farmed out to Digital Factory and Cura has been cut off at the knees. What am I missing? I am reading they are all in on cloud printing but Cura is on my machine, I'm in the office next to the printers, why am I feeling like I'm having to switch between Cura and Digital Factory for information on the printers sitting in front of me? What am I not seeing?
  5. I have been troubleshooting this issue more this morning and decided to reset the printers to factory settings and try using just a WiFi connection. The printer was stable and able to be seen by Cura all morning. I then connected the LAN cable and tried switching the connection and the printer was immediately lost. Kind of running out of ideas except to bring a few printers home and see if they behave similarly on another network.
  6. I don't expect a solution but I figured I would lay out what I have happening and see if anyone has suggestions. I manage a makerspace at a university and we have a workgroup of 4 UM3 connected through LAN, each with their own dedicated IP address. I have managed this group for about 5 years with only an occasional issue, until this week. The group of 4 UM3, initially they were on a mix of older firmware but with the issues, I updated them all to the latest "maintenance" firmware to rule out any incompatibility problems. I first noticed an issue when a printer was labeled as "Unreachable" in Cura 4.13.1 under the monitor tab. I restarted the printer and it would initially boot, show the Ultimaker logo, and then just a black screen and green ring around the controller circle. I let it sit for an hour but nothing. Eventually after a lot of experimenting, I realized that if I unplugged the LAN cable, the printer would start up as normal. I then plugged the LAN cable back in and it showed up in Cura, but...later it was unreachable again. That is when I thought maybe it was the differing firmware so I updated them all to 5.3.0. After the updates, they still wont boot with the LAN cables plugged in but I can unplug the LAN, boot them and plug them back in. Now they are all unreachable in CURA BUT I can still click on the camera and get a live video from each printer so the network must be working somewhat?!?! If I click on Manage Printer button in Cura, it launches a web browser and then I choose "Print Jobs" tab in Ultimaker Digital Factory, they all show "This printer currently can't be reached" but once in a while, one will connect and then disconnect again almost immediately. My next step is to maybe take them home or somewhere where I can put them on another network to see if it's a network issue or a printer group but I really don't want to go through that amount of troubleshooting if someone had a better idea. I plugged my laptop into the LAN cable and my computer got out into the network without an issue so I don't think it's that. I was also thinking of trying to use the WIFI grouping but setting up that in the University is a bit of an issue since me have to register each device and I don't think I could keep a specific IP address for each printer or at least the amount of work it would entail seems greater than figuring out why the LAN that was rock solid for 5 years now won't work.
  7. Are you connected to your network by LAN? Try unplugging your LAN cable and see if it boots up.
  8. I have 4 UM3 and 3 of them are running the exact same configuration of .4 nozzles, Generic PLA in Extruder 1 and Breakaway in Extruder 2. I have my class learn to use the printers and CAD software by creating and printing a key fob. When they are finished designing it, they open Cura and I have showed them how to slice it and print it to a networked printer. They choose "Print over network" and then "Automatic". When I launch Cura, it shows the queue and the jobs say waiting for "First available" but only one (sometimes 2) printers are printing while the third sits idle. I open up Manage in browser and it shows they are all waiting for one specific printer. What is going on here and what can I change to make sure the load of printing is distributed evenly? To investigate further, I went and sliced a fob and chose "First available" and it went right to the idle printer and started warming up. Weird behavior...
  9. Can I remove the USB stick from the front port of a UM3 once the print starts? Does it load the gcode into an internal memory? I don’t want to put the machines on my personal network since I am hoping to take them back to work once we have some normalcy.
  10. Tree supports are designed to support the overhangs without touching the actual model. Take a look at this video for a better explanation:
  11. Has anyone dumped Lulzbot Cura and successfully just run Cura for their Lulzbot printers? Wanting to simplify things and trying to keep track of various settings and manage materialas as well as printer settings is a bit of a hassle. Any advice?
  12. Solved. The model "came in" to Cura at some weird angles due to how it was designed. I took the STL back into Fusion (I think you could use Tinkercad as well) and reoriented the model. Once that was done, I brought it back into Cura and support blocker behaved like normal.
  13. I am trying to use Support Blocker to do custom infill percentages. As soon as I scale the support blocker block, it goes completely skew and becomes a mess. Using Cura 4.4.1. Any help is appreciated.
