0-10v spindle control?

Post by Skyler » Mon Jul 19, 2021 6:28 pm

It seems like the Buildbotics control doesn't currently have a 0-10v output for spindle control? Is there a work around way to control a spindle system that needs such an input?

Yes, you can connect a 3.3Volt PWM to 10 Volt converter to the pwm output on the DB25 connector. Here is a link to such a device that I have used.

Our next batch of controllers will have this capability builtin.

Great, thank you.

Nice, is this next batch going to be like a V2 controller? Or just some minor changes?

Would this work?

Is there a good way of powering it through the controller or will I need a separate power supply?

We expect the next batch to be available in October. There are some fairly significant hardware changes/improvements. We will be making an announcement soon.

The PWM to 0-10V converter that you referenced may not work. It is not clear that it will support a 3.3 Volt PWM signal. If you want to do this, you should find a 3.3V PWM - 0-10 volt converter. This one appears to meet the requirements:

Exciting!

Got it thanks.

Could you please advise on if there is an easy/cheap way to power it from the controller or if I'm better off getting a separate power supply/adapter?

Well, the device that I referenced says it can run on voltages between 12 and 30 VDC. So, if you run your controller at 30 volts or less, you should be able to tap the power off of the Buildbotics power supply. If not, you will need a separate power supply, or a step down converter.
