repeat movement without going through the setup again

[maxmontegtr]

Hi, I'm a total noob and I don't know what I am doing with code. That said... I made a slider and use your code, thanks!
It's awesome.
I think it would be even better if at the end of the cycle, when you click after "finish", it went back to X in e Y in (like it does on preview), and allowed you to star the program again with the last used parameters (same in and out points, same speed).
that way it would be more convenient to do multiple takes while filming, instead of having to set everything up every time.

Thanks! Max

I have modified the code to do just that - after the run finishes it returns to the start position and you can change the speed if you wish.

Thanks! There is a lot more on your code... but I figured what I needed to do... I had made a mistake setting a flag at the end after returning to XInPoint e YInPoint

[cgbright]

No problem. What Arduino are you using ? I’m currently using a Mega 2560 as the UNO won’t let me run the code - Sent from Chris Brights iPhone

I would be interested to see the code that you are running and a schematic of your connections because as I say I am having trouble running it on my uno as the display will not initialise - I keep getting the allocation failure message Sent from Chris Brights iPhone

I am using the original code (I just changed the speed and direction, but that depends on my slider design), plus a little tweak at the end for the last two "if"

//Slide Finish
if(flag==9)
{
display.clearDisplay();
display.setCursor(20,26);
display.println("Repeat?");
display.display();
}
//Return to start
if(flag==10)

Hi , can I know where can get the 3 libraries file. and what transistor use for this project pls....

any one can help ? wish to make one set of this amazing build.

[3cm3cm]

I have problem on this project, the Y motor not always working and work very weak...I have few times are working well, then after that is not working at all.....I have no idea why, check the cable connect is fine.

and the encoder is keep floating, just touch a little bit with my finger, then it will move the motor, and sometime switch to another mode like from X out change to y out....

im not sure is about the hardware or the coding or the cabling ..... I watch the video many time and Raj are using transistor and resistor in this project...but it not show up in the schematic ...

hope some one can help...thanks so much !!
