Hello there,
Ive recently completed a project on Dragonframe 4 using the track reading feature. I would like to try out motion control in my next project to expand my skill set. Does anyone know a good motion control kit that isn't too expensive?
I was thinking about getting this Arduino kit:

(Sorry about the messy address)

Thanks Simon,
I will look into those. I'm familiar with Edu's amazing work. I was unsure weather the board would work with Dragonframe or not but know I know I'll just have to worry about the motors. Could you recommend any motor's that are strong enough? If it helps the camera I use is a Canon EOS 1300d.
Thanks.

Dragonframe's Arcmoco can use several types of board. The Arduino Uno gives 4 axes and the Mega up to 8. So you need to decide how many motors you want to control.
The shield that fits on top of the Uno has drivers for 4 motors, and you need to do some bridging of connections to get micro-stepping. Otherwise it is ready to go once you have a power supply for drivers and motors. (The drivers are the units on the shield).
If you use a Mega then you will need separate drivers. I use the black box type, as I discovered the Big Easy Drivers would only handle 1A, and the geared motors were all 1.6 to 2A. The black box drivers can be bought for about £6 each, and they have switches for microsteps and different amperages.
I recommend going to OMC stepperonline, who do a wide range of motors and have been very efficient in dealings with me. Have a look at their high-precision steppers, something like a 30:1 would be good. https://www.omc-stepperonline.com/precision-planetary-gearbox/
This will give you plenty of torque and not too much backlash. Run it off 24V power supply. If you go for a track and belt like Edu, then you can get away with the ordinary geared motor, which is a bit cheaper, as the backlash is not amplified. But for the tilt and pan, where you need a further gear reduction or belt system, the backlash becomes unacceptable with the basic motors. And this is where you need the torque that a gearbox provides.
Edu's solution was to go up to the NEMA 23 size of motor and use them without a gearbox but using a worm gear. This is also a good way to go, but the motors are bigger and heavier than the NEMA 17s.
One final thing about the high precision motors. The brackets to mount them have to be slightly different to the normal motors, and I have not been able to find any online. So I bought some alloy angle brackets suitable for the normal motors and filed them out. Just another little nuisance!
