This is a new thread as the issue I had in an older thread is solved. The problem I am having now is I can connect and control my S3 using my Laptop (MacBook Pro 17", early 2011) running Mac OS 10.11.3, Carbide Motion 3.0.355, but when I try to connect to my Mac Pro Tower early 2008, running Mac OS 10.11.3, and Carbide Motion 3.0.355 I either get the “GRBL Error: Serial Port: ResourceError” or I the application opens up and then when i click on jog, the programs crashes.
See the 2 screen shots.
I will then force quit and try to open the application up and then the Icon for the application (CM) it just bounces and bounces but never opens up.
I will then restart the computer and will be able to open the application (CM) and then attempt to connect to CM and no luck.
