Arduino Rotary Table MEW 249

Andy thanks very much i will have a try tomorrow .Graham

Graham,

This link is to a version of the code that works on my DFRobot. It's been modified to make the buttons work.

Try downloading and installing it.

I can't guarantee it will work. If it fails, please complain and we'll try what Andrew suggests in the last sentence of his post.

Cheers,

Dave

hi john

is that the way you connect remote switches as i am about to wire up a control box when the switches arrive

hopefully i'll have a unit working shortly

Peter,

No. What Dave is talking about is a different version of the LCD and button shield that needs different values in the Arduino's program for the Arduino to recognise which button is being pressed. If you are wiring up remote buttons all you have to do is to solder leads onto the contacts of the buttons on the LCD/button shield and then connect these leads to the relevant remote buttons.

If you have any more queries on building up the unit don't hesitate to PM me.

Carl.

Hello thank you everybody for your invaluable help i have just got both arduinos and the keypads to work after putting so many numbers to get the right hand key to work i arrived at

850 return no key

85 return right key

230 return up key

35o return down key

450 return left key

850 return select key.

The only problem now is even with a 24volt supply it only revolves at about 14rpm as i had hoped to drive a small mill head up and down with one of them with a 3 to 1 reduction Thanks again Graham

Graham,

Have you changed the sketch to disable microstepping? At the top of the sketch you will see this line

#define Microsteps 1 // Depending on your stepper driver, it may support
// microstepping. Set this number to the number of microsteps
// that is set on the driver board. For large ratios, you may want to
// use no microstepping and set this to 1.

The figure after #define Microsteps should be 1 to give the fastest speed.

Andy

Thanks Andy i will give it a try this afternoon.Graham

thanks carl

Nick,

At the top of the code are these lines:

#define StepsPerRevolution 200 // Change this to represent the number of steps
// it takes the motor to do one full revolution
// 200 is the result of a 1.8 degree per step motor
#define Microsteps 8 // Depending on your stepper driver, it may support
// microstepping. Set this number to the number of microsteps
// that is set on the driver board. For large ratios, you may want to
// use no microstepping and set this to 1.

Make sure that the motor you are using is 200 steps per revolution, and set Microsteps tp 1.

Also make sure that the DIP switches on the TB6560 are not set for microstepping.

Hello all, thanks to Carl and others on here, Im happy with the way my Arduino RT project has finished up. One strange thing I noticed when using it recently is the way the CW and CCW buttons work in the RUN mode.When using divisions , angles or jog, the left (CW) button turns the table clockwise, and the right (CCW) anti clockwise as it should. However, in the RUN mode, the FIRST press of the left button turns the table anti clockwise, so does the other button. But if I press the left button again, it turns the table clockwise as its supposed to, and then normal after that.!!! This happens every time I select the RUN mode, then corrects itself.

Anyone else had this problem ?. Many thanks.

This sounds like the software is losing track (unlikely), resetting the stepper driver or switching between microstep and normal modes.

hi

i thought you might like to see my offering of my dividing head based on the chuck felllows deign with the software from the one in model engineer workshop
