Pin Support Sphere Challenge G-code for Prusa MK3SMMU2S and MINI+

<h4>Test your printers limits!</h4><p><strong>Pin Support Sphere ChallEnge </strong>is a way of testing your printers capabilities. It is designed to be hard to print so only well-calibrated printers with quality filaments will print out a near perfect sphere on a near perfect pin support.</p><p>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!</p><h4>Custom written G-code</h4><p>Despite the model having unconventional nozzle movements, custom G-code had to be generated. I have modified original G-code from <a href="https://fullcontrol.xyz/#/models"><strong>fullcontrol.xyz</strong></a><strong> </strong>to be able to print on Prusa i3 MK3SMMU2S and Prusa MINI. That is a reason, why you cannot just slice it yourself.</p><p>&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/310666/rich_content/e33e6cd6-feeb-4b60-975e-43999da78ce2/image.png#%7B%22uuid%22%3A%225bc827c2-2f83-4705-8415-03dcd21c2ea3%22%2C%22w%22%3A2534%2C%22h%22%3A1418%7D"></figure><h4>&nbsp;</h4><h4>What to look for</h4><p>This model has 2 crucial parts - the pin and the sphere. Pin should be as straight as possible and it should have constant diameter; the sphere should be near perfect shape. If it is not the case, then you might have problem with extrusion or with live z adjustment.</p><h4>FAQ</h4><h5>Why don't I see any print info on my printer?</h5><p>The print info (weight, time..) is calculated in slicer and later it is written into G-code. Because this G-code did not went through slicer, there is no info on that and I have not added it manually yet.</p><h5>Why is there no G-code for MK3S?</h5><p>The reason is simple. I had to do 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.</p><h5><strong>Why is there only version with PLA?</strong></h5><p>I have done many tests with other types of filament too (mostly PETG), but never achieved a perfect print. I think that there is a problem with extrusion. Unfortunately, you cant just switch to different type of filament with press of one button. That is why I published only a PLA version. I might look into it later.</p><p>&nbsp;</p><p>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: <strong>Happy printing :D</strong></p>
