Microswiss Hotend

I put my new hotend in, and can print from my K2 with no issues. Can retract and extrude filament, and passed all calibrations. But when I send a print from CP6 from my laptop runs the start and then nozzle sits at the waste bin and stays at 140 degrees and does nothing? Any advice anything I need to update in fluidd and I am not the best in there? Thank you in advance this group is amazing.
