   message when it finishes calculating:

 * It seems you didn’t specify the print speed and infill speed

 * For my SLA option, I choose DLP, print and infill speed are not options when 
   that drop down is selected. I changed it to FDM and filled in those options, 
   and hit save. Then I changed the option back to DLP and hit save again. Still
   got the “Arithmetic exception” error.
 * I now just have it set to FDM and everything work for now.
