Greeting all!

Just getting to grips with Mach3.   Any idea what would be causing my PC to beep approx. every 3 seconds whilst running the program? I can't seem to find any reference to this, so don't know where to look.

GVP.

That sounds like you have a network card that is looking for the network... run the driver test and see what it looks like. If you are getting spikes you are going to have to optimize and that can be found on the Mach support page.

hope that helps

Does it only beep when Mach is loaded? It could be motherboard monitoring software and your temps or fans are not what they should be or if its only happening when Mach is running maybe Mach and the monitoring software dont like each other.
