Testing an @Airwolf_3D #3dprinter in our labs.
I thought you already had a rating for every product out there, based on the manufacturer’s specs. Why would you need to actually test a printer in your lab?
@Thomas_Sanladerer : Because they all claim single-micron resolution based on the best-case scenario of belt pitch & microstepping, and it’s up to the machine mechanicals to make that actually happen. A machine with 1/8 microstepping and “12 micron” positioning with polymer bushings is going to print way nicer than a “5 micron” machine on 1/16th microstepping with chattery Chinese LM8UUs.
No it won’t, at least not necessarily, because there are so many other factors that contribute to the actual print quality you cannot simply overlook them. Positional accuracy is a huge factor, but that too is derived from not only the bearing quality but the design of the whole gantry and all the parts associated with it. A 3d printer is more than the sum of its parts, so to speak.
Which is exactly why you have to test them instead of looking at the numbers!
On that point I agree.
