I try to check the specs of the Solidoodle 4 to see if the rquirements are basic Gcode. But... do you really want to buy a printer of a company that even hasn't content under the 'support' button?
Maybe a tip: I have bought recently two CraftBot printers (of Indiegogo) that comes with a very promising Slicer (Craftware) and surely will work with Kisslicer as well, as it takes standard Gcode.
Although they are new on the marked as well, the documentation, support etc are looking good.
