<p>I know that CoreXY kinematics is very complex and hard to calculate for the firmware making it better to use a 32-bit board. For some reason, I can't use any 32-bit board. What problems will occur if I use an 8-bit board like Arduino Mega with a CoreXY 3D printer?</p>
<p>Everything that I wrote in this question about hard kinematic calculations was referenced from this video, <a href="https://www.youtube.com/watch?v=ySqj3gPqfrs" rel="nofollow noreferrer">HyperCube 3D Printer 8-Bit Speed Wall</a>, by Tech2c (the designer and builder of hypercube). After watching the video I doubted using an 8-bit board.</p>

If you really don't care about speed at all and want maximum accuracy, you probably want some type of Cartesian setup with no belts, only rigid lead screws which you can take to as fine a pitch as you like, and you can make all the parts as rigid as you like because mass doesn't matter (since acceleration doesn't).</p>\n<p>Note however that extrusion accuracy is the limiting factor to quality and dimensional accuracy in even a half-decent printer. Rather than trying to design something with &quot;perfect&quot; spatial kinematics for quality from the outset, I think you should look at existing printers, figure out what about them isn't meeting your quality needs, and start from there to improve. You should also figure out what your speed constraints will be, even if they're only minimal.</p>\n"}, {'answer_id': 14196, 'author': 'user77232', 'author_id': 12857, 'author_profile': 'https://3dprinting.stackexchange.com/users/12857', 'pm_score': 2, 'selected': True, 'text': '<p>Just to clarify: Examples of kinematic systems would be Cartesian (which includes CoreXY), Delta, Scara, and Six-Axis. The quality of the system has less to do with the system and more to do with the implementation.</p>\n<p>Furthermore, there are 2 main types of desktop/benchtop 3d printers that are commonly available: Fused Deposition Modelling (or fused filament fabrication depending on who you ask) and stereolithography; of which the latter, stereolithography, has better accuracy and quality.</p>\n<p>In terms of FDM however, it can be easily argued that CoreXY cartesian printers offer the best quality and accuracy (both of which are subjective btw) than either delta or gantry designs (e.g. gantry would be the Prusa i3). The reason is that in order to get the CoreXY to work at all, the overall engineering and frame rigidity must be at a certain minimum. Once this minimum has been achieved, the quality of the prints typically meets or exceeds the quality/accuracy of even a well-tuned gantry printer; and you are going to see it in the cost of a CoreXY printer.</p>\n'}]
