I think that using VFD's would make it more difficult. I happen to have a 600W brushless dc motor with a WS55-220 spindle controller on one of my machines. The WS55-220 spindle controller takes 0-10 Volts in for speed control and also has an enable pin. The motor will not turn on unless the enable p...

This might be doable depending on the type of spindle controller you have. Can you describe the type of spindles you are hoping to use?

If your question is whether the Buildbotics Contoller can control multiple spindles simultaneously and have each spindle doing something different, the answer is no.

If you want to describe your application in a bit more detail, I may be able to come up with some helpful ideas.

I think you are on the right track. You may want to look at my blog article that describes the Buildbotics API. Here's a link: https://buildbotics.com/introduction-to ... oller-api/

We looked into it a few years ago, but decided not to implement it.

I don't understand your question "What control is this on?" Can you clarify?

I think the filesystem is read only. You have to remount it to be read/write in order to save changes.

Be careful. Making the wrong changes could result in disaster.

Can you adjust the resolution on the monitor to 1366x768? I'd am curious to see if that affects the touch position.

Be careful with modifications to the RPi linux. It would be wise to make a backup copy of the sd card before making changes.

Have you tried adjusting the resolution of the monitor? My ASUS VT168H runs at 1366 x 768 resolution. You can also try adjusting the sweep frequency. Available options are usually 50hz and 60hz.
