Gr5 – Sounds like a very good plan of action. A superficial check of the wiring has revealed nothing broken or loose. I have printed a new enclosure for the print-head; so I was planning on taking it apart anyway and this will be a good time to clean and check everything. This alternative wiring that goes to the print head, I was puzzled about it during construction and I still am. Just what is the purpose of the alternative wiring? I like the boiling water test! And this may be a new use for the printer; when we are not printing we could make some tea! Thank you for your feedback, very helpful.
SandervG - Yes, Ruth (my wife) said, “I’m sure going to miss Henry.” He was a good little bird; but think about it, he sang all those years and never once did he attract a mate!
Yes, the blue light was on. What does that mean other than the signal cable disconnect?
Yes, I did get error messages; something like ‘maxtemp’. This was early on, right after construction and during some of the test runs. I would turn the Ultimaker off and let everything cool down, check a few things and then give it another test run. I was able to correct a few problems and learn more of just how everything works on this marvelous little unit. It is quite a wonder! Thank you for your feedback.
C – Well, in this case I wasn’t planning on going above 220. So, when I noticed the smoke and the smell, I first thought that the blue tape was reacting to the heated PLA. When I discovered that the tape wasn’t the problem, I then thought that the Acryllic Build Platform beneath the tape was somehow reacting to the heated PLA. That wasn’t the case either; the smoke flowing from the nozzle became visible when it hit the tape and Build Platform. And that is when I realized that the problem was in the print head itself. Also, it was then that I noticed that the aluminum block with the brass nozzle was sagging a little to the right. Flashing red lights and sirens, that’s a good idea; but, the reactions may still be like mine – What do I do?
Safety, sooner or later will come to figure in the design of these units and redundancy is always the best and most successful route. Also, since we have a USB connection why not have a diagnostic program that could check all of the variables and provide a report with detected issues and suggestions on how to address them? Maybe down the road! Thank you for your feedback.
