SainSmart Coreception 3D Printer Trouble Shooting

1. Cura settings (specifically print head size settings and why they are)

There is a known bug for the x-min and the y-min. These settings are used to set the hot
end size for the options to print all at once or island. This is not a concern with the
coreception as the print dimensions takes into account the size of the print head.

·For versions that do not allow the recommended settings use the below:
·x min = 0
·y min = -10
·x max = 10
·y max =10
