Dan 911 can you post a link to the latest plug , I have a issue where 5% of the time when executing a manual toolchange and the code issues a M5 the spindle does not stop , UCCNC turns off water cooling pump so I believe it is executing the code properly . Seems to only become a issue since updating to the latest software , the cure is to manually turn on the spindle via uccnc and then turn off , I believe I am using HYPLUGIN14
