I just upgraded to the ex controller I used the router successfully. Switched to the plasma used it successfully when I switched back to the router I got this error code with this picture on the graph job. Any help would be appreciated.

Looks like you’re using the wrong post processor. Are you using your old Mach 4 post or did you switch to the new Avid EX post processor for Vectric/Fusion?

Thank you it was on the Aspire side of things. I loaded the EX PP for plasma but not the Router. Thanks again for your help!
