My rest project

[Fast14riot]

Simple me thinks using a drill motor and trigger controls would be simpler. But, programmer I am not. I leave that for the missus, lol!

It would be simpler but it would not have the resolution I want or things like go home or the atmospheric sensors and display. I'm going to try and have the display show level, temp, pressure and humidity.

I have not started that part yet, I figured I would get the form down first. If I have any questions would you mind me asking?

No problem. Be glad to pass along anything I have learned. I would use a stepper motor to move your project. They are inexpensive, readily available and code is available to use for the project. They also have a holding torque. The size would probably be determined by how much holding torque you need. What thread are you using to drive the movement?
You could have a display to show how much you move. You could convert the movement to display in moa or whatever you want. I guess you could enter distance and have it display inch moves. You could zero the display manually or each move could be a relative move. It seems straight forward to me.

Look at nema and 17 or 23 steppers. You could mount them recessed into the base plate and really shorten the overall height if needed. It sounds funny but you might look at the lower powered motors for a frame size as they are shorter in length. At the same holding torque a nema 23 may be shorter than a nema 17. I rally don’t think you will need much motor.
Are you going to run one screw or two on the windage?

Get the old computer involved and use a joy stick like the gamers use. Even the speed of its action could be adjusted as needed.

I don't know how that stuff works, but if it can accurately and precisely control a milling machine, it could control a rest.

Next comes Ai which doesn't need a shooter. The possibility is endless.

The motors I have now are worm gear. They are a smaller version of what is being used on brass and bullet collators. The windage is run on a rack and pinion.

This is fantastic! Well done! Do you mind sharing printer / filament / print time info?

 

[kris bassett]

Used it for the first time today. It is a little tall but I have already fixed that in the cad model. Here are a couple pics. The first Pic of the target is 3 shots, the next Pic is the same target with 5 shots. I managed to pull my 4th shot a bit (the 4th always gets me lol). The next issue to solve will be the rear bag. I just don't like it! Hopefully the one I'm building will be better.

I can however smack the bowling pins at 300 in the "head" with every shot!

Can you lower the rest about 3 inches ?

I did this yesterday in the cad model. I'm waiting on some more filament. Once it arrives I will print the new version.
