Cura does not come with the Stepcraft PH-40 as a pre-configured printer, and thus requires creating a custom printer profile (please see the PH-40 First Steps UCCNC manual for more information). Below is a PDF containing the parameters for your Cura profile. Please note that the nozzle diameter setting is dependent on what size nozzle is fitted to the print head.
