That’s too slow for the stepper motor, especially in micro-stepping mode. Yes, ESP32 allows you to run multiple threads on both cores, but the fastest task scheduling is only 1ms. The basic examples for ESP32 web servers are synchronous and blocking. I do have to say, that I had some problems with running both ESP32 WebServer and TMC2209 stepper driver. Yes, there are 4 buttons and an OLED screen, but the whole idea is to have it operate by remote control from your smartphone! The only thing to remember is that the camera slider is calibrated for 1:8 microstepping (TMC2209 default), so other stepsticks should also be configured for 1:8 micro steps.īecause it’s ESP32, WiFi and web interface were an obvious choice. Thanks to this, the design is compatible with older and cheaper step sticks like DRV8825 or A4988.
Arduino camera slider reddit serial#
I have chosen TMC2209 stepper motor drivers but decided not to use a serial interface and connect it to ESP32 with a standard step/direction interface. The NEMA17 stepper motor is connected to TR8 8mm lead screw. 24”) 2020 V-slot aluminum profiles and 3D printed elements. The whole contraption is built with 500mm long (approx. ESP32 provides both WiFi Web interface for the slider and drives a single NEMA17 stepper motor with a TMC2209 step stick driver. My motorized camera slider uses ESP32 with Arduino. The other option is to build one yourself. You will need at least a few hundredths dollars to buy something useful. But if you want a motorized slider with remote control, you might discover that they are not cheap. When you order parts from China: Shipping can take a long time, taxes depending where you live, Quality may not live up to your expectations.Ĭheck out my YouTube Channel and if you wish to support please subscribe to my channel.If you go into the video production, even as simple as short videos for YouTube, you will discover that to shoot better B-rolls and add some dynamics to usually static shots (if you do not work with a real cameraman), one could use a camera slider!

In the Third Video i show the Camera Slider in action, it is almost done, i plan to make some changes to the menu and code of the Arduino, and i am also having a bit of trouble with the timing belt, i think it is a bit to skinny,Īnd i think i have to move the pulley bearings closer to the pulley wheel to get some more grib on the timing belt.Īll in all it is working like i planed it to, but i deffently need some tweaking, and i will continue to develop on this for some time.įor now it is time to make footage with it, so please check back later. I will make a schematic and release my code here, i just need some time to clean it up a bit. I also assemble the electronics in a plastic box, not the most elegant way, but was in my flat so i had limited access to tools. In the second video i build the slider, i made a mistake on the layout so had to redo it, but it turned out pretty well, i plan to trim away som of the unused edges of the aluminum plate to reduce the weight. In the First video i’m building the frame and slider mechanism, The part list is further down, not every part is on the list as some of the parts where scrap metals i had laying around. I spend a lot of time looking for parts for the build, and found the most of the parts i used in China, and i think that is the reason i was able to build this for under 100$ This article is about how i made my own smart camera slider, i wanted to build my own camera slider that would be used for both video and timelapse photography.
