Well cura has a little status window and it has a text box.... I'm assuming I can use that to send commands, but I don't know what the command is to stop the fan. It seems to be doing ok this time. The only thing I did was put a big old fan on the power supply just in case and cinched up the wires to the hot end a little better as they were hanging below the fan duct.

It's very annoying... one of those watched pot deals.... It was printing fine last time so I went in the living room to watch a movie and it crapped out on me. Right now I'm on my computer anyway and wouldn't you know it... no errors. I don't mind checking in occasionally, but this is a 6 hour print. It's about halfway done, so hopefully it'll make it this time. The solution for rapid cooling is to insulate the hotend, so I'll look into that. And of course overheating just needs more fans, so I'll go through my junk drawers and start throwing every 12v fan I have at it.

While I'm waiting for this to finish I took a look at tinkercad. it's surprisingly robust. The only thing I don't like about it is there doesn't seem to be any way to work on models at the vertex level or the ability to delete/add/weld vertices. I'm old school. I usually plop down the basic shapes and then do all of the detail work with vertices. I want to try one or two projects with it though. No having to install a bloated 3d modeling program is a big check in the pro box for me.

I went through the included tutorials, then a few from this youtube channel:

With that, I've been able to pull off everything I can think up, except for complex curves.

The only annoying part is that every single thing you do is recorded in the file, so designs you've worked on a lot and redone parts of get so complicated that they take longer to load and sometimes get glitchy. You can work around this by saving individual pieces as stl files, then importing them into a new design file. Then they only show up as one shape instead of all the shapes & changes that went into making them. Of course you can't undo or ungroup the parts that went into it.

You can also copy and paste from one design to another, which is helpful.

EDIT: BTW for some reason I can't access the drop down menu to change the snap grid size on the new Beta version (lower right corner of grid area).
I can click on it, but the options are always hidden behind the tool panel or right edge of the screen. Could be the 1600x900 resolution on my laptop.
If you have the same issue, you may want to use the Legacy Design option.

But I doubt its because the fan is cooling it to fast. I would recommend checking the hot end and heated bed's thermistor, it may be loose or out of place or bad. Its a good idea to pick up a cheap laser temp gauge and use that to confirm the hotends actual temps.

I agree that a cooling fan is very unlikely to cause a thermal runaway error. I'd check the temp sensor wiring very carefully. After that, some of the Skynet releases have had some bugs. I'm still on 2.0 because it works for me and I hate to fix what's not broken. 2.3 (or 2.3.1) seems to be pretty good from what I've read but some of the in between versions have had reports of thermal runaway errors.

I think it was just glitching out for some reason. I'm currently running it via usb cable and I think when my pc gets busy it is sending odd data or something.

The latest print turned out just fine and I checked the print every 15 min or so and there was never a fluctuation in temp more than a degree or two. I checked the wiring the whole length, even removing the covering and I couldn't find any kinks or breaks.

Anyway my pcb cover turned out great. As per usual there was a design flaw in the author's design.... the box hit the right bolt on the z limit switch, pushing it down, so I had to take it off and dremel out a small hole. It looks nice and tidy though.... I'm only hoping the vent holes are enough to keep it cool. I'll probably mount a pair of fans to the outside just in case.

Btw.... I've been using painter's tape on the bed because the included stuff sucked and I have a real hard time removing some prints. My tape is ruined every two or three jobs. I was thinking maybe contact paper or something. Are there any pre-made covers out there that actually work?
