SOLD Igus DIY Motorized Slider for sale

[Mark Williams]

Unit is in very good condition and operates smoothly. The slider can be used manually when the belt is removed from the servo drive hub for near silent operation. When used with the servo drive engaged there is an audible whine from the servo to take into consideration if recording audio.

Unit is a very simple design which allows for easy servicing. Under power the carriage travels in both directions at multiple adjustable speeds from barely moving to about 20 seconds to travel from one end to the other. No automatic stop when carriage reaches the end of the rail. Power plug must be removed from the controller to stop carriage movement. You could easily add an on/off switch. Tripod not included. Also, includes a padded rifle carrying case which provides excellent protection. Total cost for parts was $355 excluding tools to construct. I am asking $235 which includes shipping to CONUS via USPS mail. Payment is through PayPal only.

Includes:

- 28” DryLin W16-A Linear Rail

- Carrige for rail, drilled in center with 3/8” mounting bolt installed.

- Nylon end stops installed for rail.

- Drive belt tension easily adjusted using wing nut.

- Servocity HS-5485HB continuous rotation servo.

- Drive belt.

- Servocity manual servo drive controller which allows for variable speed in both directions.

- Battery pack with 4 rechargeable AAA batteries.

- Bogen 501PL tripod mounting plate attached to center of rail via 3/8” tap.

- Blackhawk Sportster carrying case.

What's the max amount of weight it can support?

Thanks

I have had a 5.5lb HPX170 on it with no problems. The rail would hold much more than this. It is thick and strong aluminum. Where you hear that some get flex on the Igus IMO is not the rail but the tripod head mounting. I use a heavy duty tripod (not the one in the photo) that can hold up to 35 lbs and spread the legs wide so the slider stays well inside the footprint of the legs. The servo is rated for 89oz/inch and you can read about it here http://www.servocity.com/html/hs-5485hb_servo.html
The servo and belt drive is intended to work horizontally not vertically.

Thanks for the reply, Mark.

When you say horizontal only, is there a degree that you need to avoid going over? How horizontal is horizontal?

Is it possible to use w/o the belt? Basically interchange?

 

[Mark Williams]

With the small teeth on the drive belt you would want to be pretty level. However, that is my experience with a 5.5lb. cam. If you are less weight than that you could be a little off level or go manual and you can do vertical if you need to.

 

[Mark Williams]

Yes, you can go with or without the belt drive. Just release the tension via wingnut on the belt, remove it from the servo and idler pulley on the other end and slide to your heart's content. Alternative is to remove the belt completely where it attaches to the carriage (see photos).

I would suggest that if you want to use this on an incline, you buy one of Servo City's gear reduction units for the servo. Servos in general are pretty weak, I wouldn't try hauling a 5 pound camera up a 10+ degree incline with the one listed. Some of their gear reduction units could probably haul a 10 pound camera up a 45 degree incline. Send them an email about your application and they will probably be able to help you out. One advantage to using a gear reduction is that the camera can move more slowly, might be a negative depending on your shot, but usually a positive.

I would probably put a spring on the end of the belt to keep it tensioned, something fairly strong but not enough to wreck the servo. At least I would put a thumbscrew tension adjustment on it to pull it tight, but again too much will wreck the servo.
