  1. My students are not in the classroom right now, so the network traffic isn't what it was earlier.  I can attempt to get that information next week when everyone's in the classroom again.  The CPU (i7) and memory (32GB) are not shown as bogged down in the TM, and LanSchool hasn't caused issues with other intensive programs, such as Solidworks or Adobe CC.  While Cura is locked up, the rest of the machine is fully functional.  There is a log loaded into my response on the 3.3 Beta Introduction post that ought to show what the logs look like when it's bogged down.


  2. I think I have isolated a major software clash.  LanSchool, software used to monitor computers in a lab setting, and Cura ran together results in very poor Cura performance.  However, if you exit LanSchool completely, including the LskHelper in the Task Manager, there is a significant increase in performance.


  3. I haven't tried it with my Macbook, but with my Windows machine, disconnecting from the network enabled it to work like a champ. You could give that a try to get your settings right, reconnect and send to the printer.  If you haven't already gone into the plugins menu for customizing Cura and deselecting Octoprint, I would do so, as it made a substantial difference for me.


  4. With a wirelessly connected printer and a wirelessly connected computer in a school setting (large network), is it possible this is causing the issue?  I can do things on the internet/computer just fine, but whenever the wireless network adapter is active, Cura dies.  I started Cura 10 minutes ago and the processes are active in task manager, but Cura has failed to pop up yet.


  5. I tried this and there was no improvement.  Without looking at the Cura code itself, I noticed in the logs there are communication requests to the printer, which it obviously needs for the monitor aspect. Is it possible this is what is slowing it down? Could there be a way to toggle the feed/communication? Perhaps have it send a picture every .5 second versus video?


  6. My guess would be the orientation of the lines is providing greater surface area across where the force is being applied, specifically layer to layer. If you were looking at a compression force along the sides (perpendicular to the z-axis of the print) I would imagine the triangles would hold up to more.


  7. It would be better for the longevity of the electronics if you fabricated a door system and hood onto the frame itself and pulled the X and Y axis steppers out into a direct drive setup. You could leave them inside the enclosure if you wanted, but I would recommend getting some cooling fans then. You won't have to worry about the spool as the glass transition is much higher than the printing environment would be.


  8. Hey, there IS a manual for the kit! I was super confused, because the link on the product sheet is to assembling a whole UMO+... Dang, I was making inferences on that and trying to figure out how it was designed to be incorporated into older electronics...


  9. Gotcha... See here I was thinking the "SWITCH" was wired to the physical switch on the shield to disconnect power from the PCB... Now that makes sense... Wow...

    Is there not a power disconnect to the small PCB?


  10. I think I've got the wiring for adding this to my UMO correct, but I'm having some issues. I've got the dual extrusion kit up and "should work" (I haven't done any calibration but both hotends heat display temps correctly). Now I'm trying to get my HBK working and there are a couple of things I've got going on. First, I don't think my "switch" is working correctly. The LED is constantly on for the small PCB, regardless of the switch position. I would normally be okay with manually disconnecting the power if everything worked, but I'm not getting any power to the heated bed. Thoughts?
