I understand M3S and M4S only work if you have the $700 motor on/off control box. I don’t, but since the program can turn the motor on or off, there must be a sequence one can send out the USB port that will turn it on and off. I’m thinking a Python program should be able to do this. Has anyone tried this?

I don’t understand what your question means in the context of Carbide 3D machines.
You should be able to control the motors by sending the appropriate G-code commands over the serial connnection.
I think they are assuming that you have to have a vfd and spindle for the controller to automate the operation of the spindle/ router. And by motor they mean router.
This should help them.
Yes, thank you for your comments. I have bit runner driving the standard motor and the file generated by Carbide Create makes a file able to turn the motor on and off. If I had the VFD option, I could use the MIDI commands M3S M4S commands to turn the motor on and off. These commands don’t work without the VFD. However, the G-Code command string created by Carbide Create has the ability to turn the motor on and off. It does so with a command through the USB connection. If I knew the bit sequence to do this, I could write a Python, C, Visual basic or any kind program to do this. Has anyone tried to do this?
You need to both turn the motor on, and set the speed sufficiently fast to allow it to start.
M3 S10000
should be what you want for on.
Okay. Let’s start from the beginning here.
What motor do you want to turn on and off?
Are you saying you’re not able to turn your router on and off with a bit runner? Because that’s exactly what it’s supposed to do. And it’s controlled via g code.
