Yep sure can Steve, thanks! A lot of it's Greek at the moment but looks like it'll be a big help when I get back on my lathe project. I been led astray by other projects lately.

Steve do you have any info you can share on how you did this? I feel sure your methods were as clever & well thought out as the rest of the project. No rush, just when & if you find time.

that board sets timeout if there is a fault and sets speed / direction by relay inputs.

Where did you find that board Steve? You do some pretty amazing stuff! Can't wait to see it working.

Here's a link to the manual Marty. https://littlemachineshop.com/images/ga ... adeKit.pdf

How did you get along with the latest tips greenail? Did you ever get it working to your satisfaction?

right now, 0-10 vdc and 0-5 vdc analog out is the only way to control a spindle motor with Acorn. we are adding PWM out and the ability to use an axis output (step and direction) to Acorn CNC12 software which will be backward compatible with all Acorn hardware!. so yes with a future software update...

Shouldn't that be "The lathe has a working encoder connected 1:1 to the spindle that is controlled by the inverter."? I don't think it will work any other way.

Wow! That is a serious machine you have there and what a a beautiful job you've done on it. Kudos to you sir!

This should form the basis for a self-contained assembly comprising the motor, belt drive, thrust bearing and ballscrew with minimal impact on the machine head itself (requiring just 2 tapped holes). WOW, that is truly a work of art! :) It gives wannabe machinists like me something to aim for. How ...
