Need some help from the auto-rotating monitor experts...
TopJimmyCooks:
I may not have explained well enough why you don't need both an adjustable length belt system and a tensioner. I looked at that tensioner, it's 75$. This seems crazy out of proportion for the job at hand. mount the motor on a hinge and let the weight of the motor provide the tension. I think that mcmaster rod flange was $25 plus shipping. You're going to have more cash in hardware than in a display at this rate. I think you've jumped the shark. If your budget for rotation is $500, go read ond's thread ~page 7. two pillow blocks is a better solution. direct drive is better. with a belt you'll lose your positive positioning and you'll be back to limit switches. Consider before placing those orders Dude. All my rotation hardware was $65 including a dedicated usb motor controller, after I sold some spares on to others.
Can you tell its been a ---smurfy--- day for me?

No worries man. I come here to get help and look for cool ideas. Some stuff I'm all hands on and others I'm not. Stuff like this is not my specialty of strong suit so where as for you to design a system to do what an auto-tensioner would do, I would prefer to save the time I would spend bumbling on something that was half ass and go with a rock solid part. The door hinge is a cool idea but I know this would work the best. I also had a 50% off coupon with grainger from a buddy at a machine shop so I got it for $35 with free shipping.
So here's the thing, I've gotten a bunch of great information but when it comes to moving 30 lbs at 45" across the consensus from all the motor experts on various forums I've been trolling say I need a metric ton of horse power. So lots of oz*in torque. To go with Gears like OND I would need a stepping motor with north of 1000 oz*in torque or a massive gear box. Stepping motors/gears of that nature are insane expensive and big/clunky and want a lot of juice. So, I'm just buying parts now to experiment. As far as I'm concerned this is all throw away to me understanding how to actually build this right.
If it works, awesome. If it doesn't, no big deal. I'm at about $100 on parts right now. Building the networking and virtualization of data centers, my job has put me in touch with a lot of people from many different fields. I just called in a bunch of favors and got a lot of parts for either cost or %50 so for me it was a fun way to experiment.
In the end, I could have been smarter with what I purchased but honestly, I just want to learn this stuff and what better way to learn than just dive in and learn by trial and error.

You've been warned, it's an addicting hobby! I am already planning my second...

Pulling this back to the original topic for just a moment...I got around to setting up the motor today and it worked great!!! :cheers: I can't believe how easy it was...I just needed a push in the right direction.
Now I've just got to learn the ins and outs of the software and slap together my LCD, wood, and motor! ;D
Thanks again guys!

Shame on you for not posting a pic or video with this great news. What a frickin tease.
Glad it's up and running. :applaud:
