Behind the Scenes #1

The next big project is already in the making! 

The 100 comes with a promise of quality. This printer is capable of accelerations of 100,000 mm/s2. This promise of quality can only be kept if the installed components are manufactured with precision. 

And here comes my greatest pain. If you buy linear rods from aliexpress today, all the sellers promise you that they will be manufactured to the highest standards (h6) and with the best tolerances. With good rods we are talking about tolerances of 0.006mm. Bad rods, on the other hand, have tolerances of 0.025mm. We are moving here in orders of magnitude in which the buyer has no chance to distinguish good rods from bad ones. Without expensive test equipment, you are at the mercy of the manufacturer's specifications. 

I tested bad rods in advance, the result was that the toolhead blocked from an acceleration of 20-25k mm/s2. I am already aware that there will be users in the community who will be disappointed because the printer they have hoped for is not performing as they should.   

I will illuminate this problem in detail and I have the claim to scientifically and independently of manufacturers to assess the quality of different components. This is not easy, as it means that I have to buy components anonymously from the various manufacturers and in significant quantities to tests them. 

A lot of youtubers out there approach manufacturers to get free components for their tests and the manufacturers are happy to take this deal because it means their products are promoted. I find this approach difficult because you cannot be sure whether the manufacturer is picking out specific products for the test case that may have been better than the average. We all know that quality varies and I don't want to be one of those who recommend products based on samples the manufacturer provide me.   

I think the approach is correct, even if it is a very expensive one. Therefore i've ordered for the first part of this video series Rods & LM8UU for the tests worth over 2000 USD. Besides the quality of the parts I want to test different types of LM8UU like steel bearings, drylins, sinterbronze, steel ptfe or brass graphite. For me it's important to challenge the baseline I've set in the first place and find out if there is a better combination or more quality parts than I chose before.

Today I paid in advance to be able to take the next step of this project, in my vision I would like to find enough people who appreciate my work and are willing as Patreon subscribers to take on the financial costs associated with the project brings to participate.

So if you want to be part of this project and support independent scientific research, to help me to make this printer even better, then become a patreon.
