"Connection Error"- Message when I first open Estlcam on mpcnc

I tested the x,y & z axis with pronterface thru Cura & everything worked fine. - I have just finished the setup for “The Crown” - But , when I hit connect on Estlcam I GET THIS MESSAGE --“Connection failed” -“The parameter is incorrect”- I just dont know where to look ?? thanks Joe

Do not hit connect.

Thanks for the comeback – turns out I needed to change the com port on my laptop. — Joe

You are not connecting to ESTLCAM directly correct right? That will flash it’s own firmware, you do not want that.
