4 minutes into a cut, ESS data totally dropped, last Goto code still going, but shut down spindle, which resulted dragging bit across material. Cannot get Mach 4 to communicate with CNC anymore? Anyone encounter this snafu? ---

When you do get it going again be sure to set this up (see pic) this will prevent dragging the work piece around if the spindle stalls. It will send a stop code to the vfd which sends an E-stop code to the controller. ![Screenshot 2024-05-18 214545](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/b/b58b2a8d67ed1de8ecc7ddcefce049e3ae6e05cd.png) ---
