I have received a number of emails from users that have described this or that issue they've had with their Cube printer. Some have had clogged heads and others have asked about the using the CubeStick glue to best effect. This video covers the following topics...
Setting the Head Gap
Nothing will clog a 3D printer faster than when the print jet is hitting the print bed. Yet, we need a very small gap to ensure that the first layer of filament is properly laid down on the print bed. A TWO STEP process for setting the gap is demonstrated along with the paper I've found that works the best for me.
One of the most challenging thing for me, when going to the new 2nd Generation Cube from the 1st Generation Cube was the different behaviors of the two different glues. The first generation Cube used a heat activated glue and, frankly, was a LOT easier to use both before, during and after the print job.
I found that I was having a LOT of trouble getting parts to stick immediately after I'd cleaned the print bed. And, I didn't realize that by trying to solve the problem by applying thicker coats of glue only resulted in transferring glue to the little rubber cap over the print jet... essentially gluing the flowing filament to the cap and not the bed.
Finding the proper gap helped. But, finding a more reliable system for applying the CubeStick was the real solution.
A Tip When Changing Cartridges
For a long time, I created some problems for myself because I did not understand the correct timing for pulling on the filament when removing it to change cartridges. When the Cube team explained the steps of the process that the Cube takes when removing filament, I came up with a visual clue for myself that allowed me to more easily go with the flow when removing filament. The result is no more instances of broken filament inside the print jet!
The Correct Way to Insert the Cartridge
While teaching a 3D printing class at Freestate Challenge Academy, we had two different instances where the little metal contacts in the cartridge slot were broken as the student loaded cartridges. From this experience, we learned two things. (1) The correct process for inserting the cartridge and (2) how to solder in replacement contacts. We will show the latter later. But, for now, this video demonstrates the SAFE way to insert new cartridges to avoid the potential for breaking the contacts.
This is the first of the videos that I hope to bring you regarding the Cube 3D Printer, itself. As will be clear, I do not write a script. So, you will hear some obvious errors... such as when I talk about lowering the head when I really mean the bed. But, I'm trusting that the information is useful enough that you will forgive my slips here and there. I have to do these videos and tutorials in the limited time that I have to do them. So, perfection is NOT an option. :)
I have made the difficult decision to use the YouTube "Monetize" option to help offset the costs of the investment required to bring a higher quality of videos to you. I know that it's annoying. But, hopefully you will find some of the products and services advertised useful enough to click on at least some the ads.
That investment, by the way, included a new Panasonic HC-X920 video camera and new LED 100WA-56 / LED 200WA-56 lights. I mention this because these products have only recently been introduced and some of my fellow members of the DPReview forums have expressed an interest in seeing how well they perform.
If you have the bandwidth, try viewing the video in HD 1080p, to see why I feel that investment was well worth it. I love this combination!
Well... with that said... here is my first 2nd Generation Cube video!
