A large firmware upgrade with a focus on the current suite builder. The printer is already equipped with a print bed for automatic leveling, a build volume of up to 25x21x20cm, a liquid crystal panel, a hot bed, and almost all the features that people would expect from a desktop 3D printer . This announcement will definitely make the makers even more Excited.
New firmware (for all Original Prusa i3 MK2 model) is called a focus Calibrate XYZ function, which automatically corrects uncalibrated 3D printer, thus printing a first layer of error can be avoided. Anyone who has used a 3D printer knows that a flat 3D printed surface will at least cause distortion of the print, and in the worst case, the extruder nozzle will be damaged.
You should have heard more than once that bed leveling is based on a 9-point sensor system, and of course you need to consider minor defects in flatness on the plane. This means that even if your print bed is technically horizontal, the surface may not be. So you need to generate a high-resolution surface height map that allows the printhead to move along it, resulting in a perfect first layer.
Now let's look at this new firmware version. The problem is that unless you have a perfectly built MK2 3D printer, the calibration points are usually lost. But to be honest, building a printer with a kit is tricky even in the best of circumstances.
But now, as Josef Prusa pointed out, "The measured data will be used to verify that the built printer is good enough and that the results are not optimal. The geometry of the assembled 3D printer will be calculated and then Automatically compensate and then get the perfect precision parts!"
While advanced hardware makes the MK2 work, it's the constant open firmware and software tuning that makes it all work. A few years ago at MakerFaire in New York, Josef said: "Basically all the machines you can see there, the limit is not hardware but software."
Therefore, after years have passed, he still seems to keep his creed. He and his team are constantly working hard, which has made the company's achievements today. This is a milestone for any 3D printer company.
