Description
Pin Support Sphere ChallEnge is a way of testing your printer's capabilities. It is designed to be hard to print, so only well-calibrated printers with quality filaments will print out a nearly perfect sphere on a near-perfect pin support.
The print setup is easy - download G-codes from above, get them into your printer, load in a PLA filament and let the print begin!
Despite the model having unconventional nozzle movements, a custom G-code had to be generated. I have modified the original G-code from fullcontrol.xyz to be able to print on Prusa i3 MK3SMMU2S and Prusa MINI. That is a reason why you cannot just slice it yourself.
This model has two crucial parts - the pin and the sphere. The pin should be as straight as possible and have a constant diameter; the sphere should be a near-perfect shape. If it is not the case, then you might have a problem with extrusion or with live z adjustment.
The print info (weight, time..) is calculated in the slicer and later written into G-code. Because this G-code did not go through the slicer, there is no info on that, and I have not added it manually yet.
The reason is simple. I had to make a lot of testing and a lot of trial and error to get this G-code running on MK3SMMU2S and MINI. Unfortunately, I don't have access to stock Prusa MK3S. Because of that, I don't want to release something that does not work or, worse - can damage your printer.
I have also done many tests with other filament types (mostly PETG) but never achieved a perfect print. I think that there is a problem with extrusion. Unfortunately, you can't just switch to a different type of filament with a press of one button. That is why I published only a PLA version. I might look into it later.
If you have any questions, problems or suggestions, write them in the comments or message me. I will be happy if you leave some feedback. And as Jo would say: Happy printing :D
