3D Printing - "It's all about design and quality output. Not how fast the printer can run."
I think I may have just avoided loosing $300 I was going to spend on a Cetus 3D printer. It’s a made in China product that got started through a Kick-start campaign. I tried to register on their web site so I could place an order for their smaller machine.
It seems there is no one at home in China at 1:30 in the afternoon (their time) The website would not generate the confirming email to which I must respond to prove I am a real person. I eventually sent an inquiry to them through their support desk. I received two very quick and obviously automated replies from Jason Wu. aka "Team Cetus"
If nearly burning down my Delta printer isn’t bad enough, I also have a problem with the Cartesian printer. It has so many run-hours on it, I have worn out the bearing in the extruder cold-end cooling fan. There is probably a sleeve bearing in this axial fan and the blades are barely spinning. It is supposed to run all the time at full speed when the printer power is on. Well, it doesn’t spin full speed now. It almost stops spinning. I can count the revolutions by just watching it.
Fire in the Hole!
My delta printer just about burst into flames in the middle of a print job. The printer was modified many months ago so it could use a heated print bed for printing ABS. I discovered soon after the modification that the controller, which is located under the print bed, could not deal with the extra heat when the printer was used for ABS printing. It worked fine about 50 – 60 degrees Celsius, but any higher the controller would eventually go berserk and die from heat stroke.
I am sitting in my office worn down a bit from just coming in from mowing my yard in the Texas 90-degree heat and humidity…
My thoughts drifted to my three-D printers I have in my office. They need to be making something.
Spool Hole Theory
I read over and over again, rants from novice 3D printer users about the size of the hole in the spool of filament. They assume the manufacturers are total idiots with their usually large diameter center hole they build into their spools.
