OpenBuilds C-Beam Double Slider

thingiverse

This uses an OpenBuilds C-beam and can be used both motorized or not. I have this up on OpenBuilds website as well which has a nice BOM as part of the project : http://www.openbuilds.com/builds/openbuilds-c-beam-double-slider.3462/. I'm using a Nema17 motor (http://amzn.to/1skFnRO) with a 5:1 planetary Gearbox. I added an parts to support geared steppers. The 8mm shaft is shorter then a standard nema17 so I had to offset the motor mount. With a 27:1 geared nema 17 motor (http://amzn.to/1Xpih7N) I can do vertical movements. The parts are : Motor Plate for geared stepper.stl herringbone gears for geared stepper.stl Geared Nema17 Adapter.stl The End Brackets use 2 608 bearings each (for a total of 4) (http://amzn.to/1TaW1z5) to support a 8mm shaft. I drilled a 3mm hole through the shaft for the herringbone gear & the gt2 pulley. I'll be updating this in the coming days with a BOM... Here's a sample video I did with the unit : https://www.youtube.com/watch?v=lrwcWFf3E8w and here's a brief overview : https://www.youtube.com/watch?v=GkWPYcDjcFU and lastly a lengthy build video https://www.youtube.com/watch?v=1Y7jwQNCfKA. In the video you'll see my pan & tilt head used : http://www.thingiverse.com/thing:1396552 I'm using a miniEngine to control the motion but any controller can be used.

I'm using 8 wheels on the double wide gantry for the most stability... you might get away with 4 or 6... 8 Low Profile Screws M5 - 25mm : http://openbuildspartstore.com/low-profile-screws-m5. 1 V-Slot Gantry Set - universal : http://openbuildspartstore.com/v-slot-gantry-set/ Misc parts 4 608 bearings - http://amzn.to/1TaW1z5. 8mm shaft - I'm using 5/16 steel shaft from home depot. I drilled a 3mm hole through the shaft for the herringbone gear & the gt2 pulley. g t2 belt - http://amzn.to/1X8UGIC. 8 m5 bolts to secure the end plates to the c-beam - I used 25mm ones from http://openbuildspartstore.com/low-profile-screws-m5/. 4 m3 45mm bolts for the belt tensioner - http://amzn.to/1R1A1Pq. 4 m3 nuts - http://amzn.to/24R5OfD. 4 m5 bolts to secure belt tensioner to the gantry plate - I think i'm using 8 mm ones from http://openbuildspartstore.com/. Edit :: I switch controllers to simplify the wiring to a Dynamic Perception NMX. Here's a demo video showing both horizontal & inclined use : https://www.youtube.com/watch?v=K0ec4FYKiSw. I weighed the slider with the pan & tilt head in at just under 10 pounds. My camera weighs about 3 pounds... so this setup is capable of lifting 13 pounds fully vertical...
