Hi all,
I have been playing with my CNC router for a while and can get it to do what I want most of the time. There is still a lot to learn though I feel.

One question I have is about the RPM's of the spindle. In the software I use you can choose a setting, but this is meaningless when machining as the spindle just runs at whatever speed the dial on the control box is set at.

Is this correct operation? Do I just control the spindles speed via the knob on the control box? If so, that seems like a lot of guess work as I have no idea maximum speed is.

If not, how do I set the spindle speed correctly? Do i set the knob half way and then play with the software? It just seems the router software Mach 3 ignores the speeds set in my cam software.

Thanks
Andrew

PS, I have a basic 3040T router

Hi Andrew,

Our spindle raotating speed is controled by the VFD (inside of the control box),by setting different parameters on the panel of VFD,the RPM can be divided into around 8 grades.So the rpm will still when it runs into this period of settings.
You may ask your supplier if they do so and tell them your VDF brand,,,everything,they might be give you some refenrence.

If you have a knob on the control box that controls the speed, then it's unlikely that you have the required hardware to allow Mach3 to control it.
You need to have the appropriate electronics, and have Mach3 configured for those electronics, to allow Mach3 to control the speed.
