Description

Here's my design of a motorized camera slider, useful for smaller and medium-sized cameras up to the size of something like a full-frame DSLR. I use it with Panasonic cameras and it's doing an awesome job! Use the touchscreen to set precise runtimes and speeds from seconds to weeks and create video shots or timelapses that would be impossible to do otherwise.
Total cost is under $60 using import electronics or a bit over $100 when using genuine Arduino and Adafruit components.

Arduino Code requires the Adafruit libraries TFTLCD, GFX and TouchScreen. I've provided known-good versions of the libraries for download, but you can most likely find newer versions at Adafruit.

Materials and methods

Core slider:
- Set of printed parts (idler_end requires support material, idler_shim is optional to align the pulley in the idler)
- 1m 20x40mm OpenBuilds rail (20x60 / 20x80 / 40x40 should work, too)
- OpenBuilds gantry set
(- Universal OpenBuilds plate)
(- 4pcs OpenBuilds wheel kits)
(- 2pcs OpenBuilds spacers)
(- 2pcs OpenBuilds eccentric spacers)
(- 4pcs M5x25 screws (+nuts))

- GT2-2M 6mm pulley, 20t, 5mm bore
- GT2-2M 6mm pulley, 20t, 8mm bore
- 214cm GT2-2M 6mm belt
- NEMA17 stepper motor
- Pololu-style stepper motor driver Aliexpress
- Arduino Mega Amazon Aliexpress
- Touchscreen shield Adafruit Aliexpress
- Click encoder
- Mini breadboard
- 2pcs 10k resistors
- A few jumper wires
- A few M3 threaded inserts

Battery mount:

@Rj_make,

Despite its price, here is an example.

https://www.newegg.com/Product/Product.aspx?Item=0RB-00AH-00010

I wanted a canon battery as I use their equipment and it would be nice if I wold only carry one type of battery around.

@Matt Abeley,

Do you have an example of the charging mounts? The one I use was suggested by Tom, because building from scratch was going to be an issue for me.

Yes, they require a magnetic field.

68f2b807f6ce5f9780ac4c41abfc6a7d?default=blank&size=40Matt Abelev commented ago

@Rj_make

Thanks for the reply.

Regarding your build video, you used a part which the Sony battery mounted into, to draw power to the camera slider.

Im just wondering what the difference is between components like these which are supposed to charge the battery instead of outputting power from it. Let me know If I haven't been clear enough here.

Also, do the hall effect sensors require a magnetic field to sense incoming objects?

Thanks

Mini 20131106 161300 androidRJ_Make commented ago

@Matt Abeley

1) You should be ok with A4988, I'm pretty sure the wiring is the same.

2) You don't need to use CAT5 cable, I just have a metric ton of it so that's what I used. :-)

@RJ_Make

Thank you for speedily replying! Its the first time in a year that I have had some support!

I just have 2 questions. Would you recommend using your driver in the video, or the A4988 stepper driver?

Why do you need to use CAT5 cable wire for the hall effect sensors?

Thanks!

Hi, Im just wondering if someone could answer a few of my questions.

I am using a genuine Adafruit TFT shield, therefore to get it to work on the Arduino Mega, I had to change some things inside the code. Though, In all diagrams, both Tom's and @Rj_Make you are wiring to VIN. How can you connect to that port when the shield is directly on top of it?

Also, I just cannot get my code to properly work. I turn on the arduino, It goes to the HALT page, then when I turn the encoder it changes to 0d, 0h, 0m, 0s, but I cannot get it to scroll through the numbers with the encoder. Whenever I scroll the encoder, it goes back to the halt stage.

I would really value some assistance, as I am really enthusiastic in trying to make this work, but I have limited experience in coding or Arduino. Please help!

Try out the driver and the stepper separately with another code and confirm if the driver is able to drive the motor. IF you manage you get them to work, THEN there shouldn't be any issue with the circuit provided by Tom.

Took me a couple of weeks too, to figure out the right drivers for the lcd shield and stepper driver, driver.

If only things were as simple as uploading code and connecting wire to make things work right :-p

@Bernardo,

Who's code are you using? Tom's code will only work with the exact touch screen he is using. Also, depending on which driver you are using, you may need to disconnect vcc from sleep/reset.

Here is a diagram of my version..

Do you have another code ?

@RJ_Make Hey! I have been reading the forum, and realised you know a thing or two about this strange world of arduino.

Was wondering if you could help me out with an issue I have with the rotary encoder.

In toms vid, when he turns the encoder from the home "halt" state, it refreshes the screen, shows it is ready and you can click to start etc.

I have connected the encoder, and this isn't working, so Im not sure what I might have to change, or do to make it work since I am still learning to code and identify code.

Please Help!!!

I've just change my drivers polulu4988 for trinamic TMC2100 in my project (https://vimeo.com/230946414). The result is fantastic : NO SOUND with the stealthChop mode !

I've bought a 150W DC-DC Boost Converter 10-32V To 12-35V 6A and i wonder if i will improve the speed and the tork of my NEMA's by increasing the DC voltage up to 24V ? (I use 10VDC for the moment).

Any idea ?

@RJ_Make i see you know your stuff here

I would need some help. I made the slider but seems something is wrong with my code. As i get it tu run i can control the speed, but nothing on the LCD seems to work. I can get no touch controls and with that the slider only goes in one direction, i can not press the bottom part of the screen to change the direction of travel.

I am curious about how the TFT connects to the Arduino. The sketch and wiring diagram both clearly show the VIN on the Arduino 2560 connected to the battery. Both of the TFTs I have bought from China, however, have pins that connect to the Arduino's VIN. If I remove this pin on the TFT and connect, it appears to work. I can't imagine this is the way the designer intended. Is it? If not, what am I doing wrong? Many thanks!

Hello everybody. I wonder about the power used by Tom (NP-970 Sony) which delivers 7.2V. Is this enough to power a NEMA ? It seems to me that 12V is recommended for this motor.

On your side, what did you use as a power supply?

I didn't think it was 3D Printed , it looked slick and smooth. I liked the modularity aswell. I would appreciate the files for the case very much.

So far I am waiting for RJ Make youtube video with the slider while I try to think of a case.

The modularity is a nice touch.

The slider looks great.

Mini 20131106 161300 androidRJ_Make commented ago

@Piotr,

As I see it, the only way to reliably reverse direction is with the use of endstops.

Even if you use a counter based system, you will be bound to always starting the slider at the same starting position every time. or incorporate some type of positioning system feedback to the controller.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

@Piotr,

It does NOT stop at the end as this might depends on each slider length...

For example I have a 24" slider...

If I remember corrector even in the YouTube clip Thomas specified that the user need to be aware and close by to turn OFF at the end.

Of course probably you can add some tiny switches at the end ...( end up with extra wiring)..or my favorite should be a code based stop.

There is another Arduino base slider where the user added a code based stop function where the motor counts the turns and stops at the end of slider.

http://www.instructables.com/id/Make-a-Motorized-Camera-Slider/?ALLSTEPS

I'm not very skilled at arduino but if anyone can "borrow" parts of this sketch and integrate in this slider that would be an great improvement.

3f0b72ad258b53f01c58119ce1342ca3?default=blank&size=40Piotr Hurny commented ago

@DEM GER

Thx, it works now. But does your slider stops after the time ends? Like after you set for 16s, does it stop after 16s?

@RJ Make

Like is said I set the timing to 16 seconds and it doesn't stop after that, its just keeps going. I don't have it yet installed in the slider. Testing the functions. And will try to add the limit switches later.

So there is no stop code in the sketch? And the timing only represents the tempo of the slider movement?

What would I have to add to the code to make the slider stop after the timing ends without the switches?

That would be nice.

Thank you.

Mini 20131106 161300 androidRJ_Make commented ago

@Piotr,

I don't * think * I saw anything in the code that does that. (I'll take another look over the code). Just thinking out loud here, Unless the current code knows the length of the rail and the starting position of the slider I don't see the count down being very useful.

An endstop system, IMO is far more useful.

@RJ Make

So the Enable thing worked and different pins and the motor spins.

But now it doesn't stop after the time shown. Shouldn't the time be counting down? I tried 16 second and it kept going forever. The 16 second didn't count down.

Could it be that I have the wrong library?

Thanks

Mini 20131106 161300 androidRJ_Make commented ago

@ Piotr

Yes, I would also connect it to GND so it doesn't 'float'.

I'll be releasing the entire 'OpenSlider' project, STL's, Design Files (STEP), and Code once I have completed building everything up and making sure it works. ;-}

Using Tom's great foundation, I wound up completely redesigning all the printed parts. I did this so I could have everything under housings.

Tom's design is better in many ways, and is most certainly easier, but in order to meet my goals I had to make some major changes.

@RJ Make

So for 1 and 3 I should disconnect the Enable pin from VCC on the driver? That would make sense for the motor part.

For 2 I do use the Cheap clones. So I will try all the digital pins.

And for 4, that's so cool, I had normal Limit Switches in mind to connect and try to code it with some luck. I assume that you need to add some magnets to the ends of the carriage. Wish you could show me how you coded it.

Thank you Man.

Mini 20131106 161300 androidRJ_Make commented ago

@Piotr

Because I used the Adafruit 2.8 V2 TFT Shield, I wound up having to rework the LCD code to get it to work well, and that required me to dig into Tom's code pretty deep.

What I've found:

1) On every driver that I purchased, the enable pin must be driven low. Setting it high, as in Toms' video disabled the driver.

2) On two separate Mega's (cheap Chinees clones) I have several 'dead' pins. Just keep looking for working pins.

3) I would also use the Enable pin. Leaving the pin low all the time will cost you small amount of wasted battery power. I'm using a boost converter to maximize torque, so that costs me a lot in battery power, but the boost converter also allows me to drain the battery down to ~3.5 volts before function loss.

4) I have successfully coded and wired in hall effect sensors as end stops.

Hi All.

Love the project and I wanted to make my own slider.

I have all the elements needed for the electronics and I managed to test the nema 17 with the driver separately.

Now I am at the stage where I am trying to make it work. The LCD works great with the rotary decoder. But the motor wont move. I changed the pins to 50 and 51 like in the comments here but I still don't get an response. I presume to only update the pins for DIR and STEP in the beginning of the sketch.

@DEM GER can you help me, how did you amek it work?

Thanks

@DEM GER

Did you change that in the sketch, just the wiring, or both?

You should probably update your wiring diagram.

@everyone

I made it...PIN50-DIRECTION

PIN51-STEP

Changed Tom sketch.

Thanks RJ for help and advise....

Now we get to 3D Print...

ON downside....I fount the system a bit noisy..from STEP motor( all are noisy)

I guess for B-roll Shots....camera MIC is not necessary...

I will upgrade the updated diagram and upload again for everyone.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

@RJ,

New Arduino Mega...EEprom clean, Upload successfully.....NO motor movement...

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

I would try different pins,

Pins are defined on:

define DIR 52

define STEP 53

@RJ

Tried again my previous setup( tested A4988 and motor) and Tom design...without success.

My previous slider libraries are slightly different as I'm using an Arduino Uno with LCD Keypad Shield.

Works perfect for time lapses.

Please see the library and photos of my previous setup at below link :

https://app.box.com/s/s21sqt4lp8qqfenb96n4rd0nor1jn0ku

I liked Toms design for B-Roll Shots..and time lapses....But can get it to work...

Tomorrow I'm receiving another mega and I will try again...

There is no communication between Arduino (with TFT and Encoder ) and motor driver.

..this is the only way I cant explain....

Arduino Mega (Sketch with TFT and Encoder works as they should) I have the right elements on display with right input from encoder and right response.

Stepper Motor and A4988 works fine on my other setup.

When connected together the motor does NOT move....

I'm thinking maybe pin 52 and 53 ...are the issue...not sure how to troubleshot this....

Maybe change with other pins ???...Dont know...

It would be great if anyone else would build the setup to have at least something to compare..

I'm stuck...

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

So if indeed the 2nd half (driver and motor) are good then we now know we have a problem in the first half. Mega, Wires, sketch or libaries.

Not sure why I didn't think of this before, but can you use (modify) the sketch from your other slider to test the base hardware on this new one? Are you using any of the same libaries in each sketch?

If the sketch works, then we know we have a problem in Toms sketch or a supporting library.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

@RJ,

I tested my A4988 and my step motor and they are fine.

I have another Arduino LCD Keypad style slider...and swap the drivers and step motor.

100% they are fine.

I can only suspect Arduino mega 2560 or wiring...

But the program, LCD TFT menu and encoder are behaving as they should with proper results on screen based on my input...

Not sure what to look for next

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

Not yet, I'm still waiting on a few things. The circuit looks fine to me, but as you know that doesn't mean there isn't a code/libaries, hardware or wiring issue.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

@RJ

Thanks..I will check the motor and Polulu 4988 today....as I have a setup from previous slider..

I can't check Arduino...I place an order for another one anyway...

I will keep you updated...

By the way did you build this setup as in Thomas diagram ?

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

Until you are willing to run the test to determine which half of the system is not working I can't help you.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

100% my stepper motor Nema 17 is working as I already used it in another style of slider.

A4988--I have 3 units and tried all of them.

One of them was also used in my previous designed slider and working fine.

Arduino and the encoder with the code the seems to work as I have the correct display elements and response on TFT screen as Thomas in his clip.

Wiring is done as in the below diagram

https://app.box.com/s/66d412frc23q4plaji25w6yjyw5mocva

NO motor movement ...

Anyone any more ideas ?!?!?

Mini 20131106 161300 androidRJ_Make commented ago

So at this point we need to split this down the middle, and test the driver and stepper.

Here is a great thread on how to test your driver and motor from Pololu

https://forum.pololu.com/t/how-to-check-if-a4988-is-fried/3542

If you have voltage on 1A-1B and 2A-2B, or if you try the other test and and the stepper fires, then the problem is either in your wiring (Bad wire(s)), Arduino or code.

Let me know how you make out.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

Thanks RJ

1) Motor is connected correctly

2) tried Sleep and Reset Jumped and disconnected

When Connected I can hear the coils in the motors ...But seems that there is no juice...Even I have a separate 12V / 4A battery with 100Mf CAPACITOR. fully charged

I added a decoupling cap between VMOT and GND -- 100uf

NO spin....even I can hear the motor trying...or at least coils...in it...

SLEEP connected to RESET,

MS1, MS2, MS3, ENABLE... all are already disconected..

Any ideas ?

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

I'm pretty sure you don't need to pull those high, well at least RESET. but like I said before it shouldn't matter.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

Thanks for looking in to this...

I'm confused....

Why you tell me jumping RESET & SLEEP ?

...they are already connected together....

SLEEP, RESET, MS1, MS2, MS3, ENABLE... all are already connected to 5V...

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER

Looks good, but you can try:

1) Unplug the motor; using a diode connect to what you think is coil one of the motor, spin the motor shaft. If it lights up, then you know you have the motor wired correctly.

2) Try jumping Reset and Sleep, don't take the pins high (it really should not matter, but..)

You may also want to put a decoupling cap between VMOT and GND -- 100uf should be good

From there we need to go much deeper.

I've added the STEP files for the ends and the belt clamp - need the electronics mount as well?

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

Hello Again,

Can anyone confirm if they got this circuit running?

Appreciate if anyone would let me know and if my uploaded below diagram is correct.

I tried all options….as per Thomas wiring, and external power to (Polulu A4988) Motor Driver…

I don’t get any movement in step motor …

Thomas I know you are busy…can you provide any feedback?

Thanks.

Mini 20131106 161300 androidRJ_Make commented ago

@DEM GER Thanks for the response. The reason I'm requesting the design files (STEP) is so that I can make modifications.

What I have in mind:

1) Provide Pilot Feet for use on a desk (or ground)

2) Removable control console

3) See if I can make that a little more (well a lot more) printer friendly

4) Integrated end stop mounts

Having the design files (STEP) should make it much easier to do some redesigning.

I don't see why we couldn't add some directional change end stops. I took a brief look at the sketch, and while it will be quite a bit of work, I think it's possible.

Cf93eccba63440090cbe033b2ebcdbdb?default=blank&size=40DEM GER commented ago

RJ Make

What help do you need with STEP ?...I might be able to help...

This is my second slider ( my previous version had an numeric LCD)>

Anyway let me know what you need and I 'm glad to help.

Myself I need help with motor wiring or stepping....as I don't get any movement...

As per End stops I saw the other day another slider(Arduino based)...that was able to count/ measure and will automatically stop at the both ends of the rail....

Is that something that we can incorporate ?

Mini 20131106 161300 androidRJ_Make commented ago

End stops for directional changes really need to be incorporated. If no one else does it before I start mine, I'll upload whatever I come up with.

I really could use the design files (STEP) Tom ;-)

Hi Thomas and thanks for uploading encoder.h.

I created another diagram at the below link:

https://app.box.com/s/66d412frc23q4plaji25w6yjyw5mocva

Please advise if you notice something wrong…

In my setup the motor (Nema 17) does NOT spin……

Please let me know if something is wrong in my wiring / diagram..

Is micro stepping correct wired?  

I tried many jump settings with no results

I hope this diagram helps others on making this awesome slider…

Please guys upload your results…/issues…

Mini  1140400 ssqThomas Sanladerer commented ago

The Arduino sketch also requires encoder.h, which wasn't included in the libraries bundle up until now. If you were having trouble compiling the sketch, just download the .zip again and add the Encoder library!

Tom, would it be possible to get the STEP files for this project. I would like to see if I can make some changes to your design.

Hi Thomas,

This is amazing and have ordered all the bits needed for this weekends build. one problem though, as i have the INO in Arduino when i verify the code it errors on the *.h files i can see some in the included libraries you have uploaded. I have my MEGA 2560 clone board here now and I'm fairly new to Arduino coding and would appreciate some help. Thanks very much

Mini  1140400 ssqThomas Sanladerer commented ago

@RJ_Make I'm using DIN912 aka ISO 4762 cap-head screws, but any non-countersunk head should work.

For the touchscreen, the Adafruit 2.8" model should also work with minimal software changes. NP-F batteries have ready-made mounts available for them if you can't/don't want to make your own http://amzn.to/2lgRVHG

And for the belt, you can usually find a 5m loop of GT2-2M belt for very reasonable prices http://amzn.to/2kz6Tvx
