[size=small][font='Open Sans', Helvetica, Arial, sans-serif]So I have two separate projects... first is a Double Slider based off OpenBuilds C-Beam... It works like a Edelkrone slider plus in that both the mounting to the tripod and the camera move along the rail... so while its only 500mm long you get nearly 1m of travel. You loose a little travel from the plates being different sizes so you end up with about 900mm total.[/font][/size]
[size=small][font='Open Sans', Helvetica, Arial, sans-serif]It can be used with or without a motor[/font][/size]
[size=small][font='Open Sans', Helvetica, Arial, sans-serif]Its still a work in progress but took it out for test spin last week. Here's the hasty video I did the has two video samples and a time-lapse at the end[/font][/size]

[size=small][font='Open Sans', Helvetica, Arial, sans-serif]I have a brief overview video and I'll be posting another more detailed video soon.[/font][/size]

[size=small][font='Open Sans', Helvetica, Arial, sans-serif]I uploaded the build to OpenBuilds which is where I got the C-Beam from : http://www.openbuilds.com/builds/openbuilds-c-beam-double-slider.3462/[/font][/size]

[size=small][font='Open Sans', Helvetica, Arial, sans-serif]I also have a video of the build here :[/font][/size]

[size=small][font='Open Sans', Helvetica, Arial, sans-serif]Everything is controlled with two miniEngine (http://minie.airiclenz.com) wired together. but any controller that can talk to steppers would work...[/font][/size]

Wow - a lot of work, you put into all this. Thanks a lot for sharing here!

Hi Buffcleb,

Nice work, what type of motor did you use to automate it and what electrical feed?

kind regards,

Rodrigo

the slider is using a 27:1 nema 17 (http://amzn.to/24vPhvN)... the gearing built into the slider using the 51:13 herringbone gears give just about a 4:1 give the resulting slider a little over 100:1... with that gearing It's able to do vertical shots, which considering it has to lift the entire slider isn't too shabby...

the pan and tilt is using two large nema 17 motors (http://amzn.to/1TXm0dy)... I'll probably change out the tilt one with a 19:1 smaller geared nema17 motor and the pan with a regular smaller nema 17... panning doesn't require as much horsepower...

The miniEngine uses big easy steppers and I run the two controllers off of a 12v 8amp hour battery... running all three steppers at the same time pulls about 1 amp... I've been thinking of adding a second 8amp hour battery and having a 24v power source for the big easy drivers... not sure but I think they might run smoother...

I did a video demonstrating both horizontal and inclined use... with the camera it weighs in at around 13 pounds (just under 13 kilo)... I picked the gearing hoping to be able to do vertical moves in a portable form and it can do that... I plan to design a lighter model next
