#4120 is the tool number With 400 steps per revolution and a 4:1 gear ratio, that would be 1,600 steps per revolution. Without any lock/unlock commands the idea is as follows: 1. Get the tool number from #4120 2. Calculate the position (angle) of the tool in degrees like: Angle = Tool * 45 3. G00 A[...

Here is the code I use to turn the turret on my Portable Collet Production Lathe that is under development. The "Raise Paw" and "Lower Pawl" sections would be replaced by the relays to lock or unlock the collet. (This code will change as the next version of my turret uses a locki...

Sounds like a feature request!

Without more information, we don't have much to go on. For gears I'd use a stepper motor controlled rotary table with a tail stock. I have 4 inch tables for the Sherline mills and a 6 inch table for the Tormach. As long as the stepper motor driver has step and direction connections (most, if not all...

Looks good! Simple and nice layout.

I've used Mach3 and I've used Acorn. While you don't need the Pro software to use Acorn, that $160 extra for the Pro software will be quickly forgotten after you use Acorn for a week.

Impressive! Very nice and well done! I look forward to seeing your future videos!

Hello, I've used a U58821 successfully from Adafruit (https://www.adafruit.com/product/158) for a homing sensor for a turret. It's 3.5 to 24 vdc so should work fine at 5 vdc. I've also used a Digikey part 620-1830-1-ND successfully for a turret homing sensor for a 3.3 vdc circuit. (This is rated 2.8...
