Why is the PMDX spindle configuration not consistently saving in Mach 4? I am running a PWM spindle (external - not using PMDX 407) I configured Smartbob for PWM spindle. Sometimes it saves and works when I launch Mach 4; sometimes it doesn't. If I forget to check it every time I launch Mach 4, it's a 50-50 proposition. I have broken several bits because of this problem. This morning it was a new expensive carbide bit. What's going on??
