Post Want 90" per minute from your Stage Zero dolly??
I've been testing the Dayton 2L010 (25 rpm motor) with a 10 pound load running off the MX2 all afternoon and........

So far so good! I've been trying to push it to it's limits to see if the L293 will croak but with this reasonable 10 pound load and under full power for 10+ full length passes and everything appears to be running smoothly. I'll keep testing and testing but these inital tests seem to indicate this is motor is looking good! ;)

PS. I've been able to get it down to .3-.4 inches per minute continuous (pulse, had to increase the minimum pulse to 200ms) and in move-shoot (interleave) mode it works great for timelapse as well... 8-)

I like how versatile the controller appears to be, it definitely opens up for some great modifications and add-ons in the future!

How much is the motor?

I have been thinking about adopting it to a different rail-type based on bearings (Low Profile Redi-Rail), for smoother motion, so this motor would come in handy for both video motion and timelapses. Perhaps you should check into that rail system, it is really great for video.

And the price is comparable to the current 1030 profile (I was quoted the following prices for a 180 cm rail (RRL34R-1800-R0 for €129,60) and carriage (RRL34C-A2-019F-C0 for €35) excluding shipping cost).

Sounds great, but I highly doubt a 10mm x 35mm rail is going to span 180cm with a 8kg load... that would deflect a lot!! :?

Also keep in mind is the cart/rail in it's self is only the foundation. There are many more aspects to getting a moco system running smoothly. ;)

I wouldn't worry about that particular rail as it support loads up to 489N (110 lb) in lengths up to 3 m (hopefully it won't flex in the middle). :)

I will test it out once I get back from my vacation to the Alpes :D

The price on the motor sounds great though!

Hopefully???... :? I think your totally mis-understanding something here, that rail is ONLY 10mm x 35mm. There is no way on earth that's going to support 110 pounds spanning 3M unsupported. Just take your ruler and draw a 10mm x 35mm square and then imagine that spanning 3m!!! 1000% Impossible!!!

I understand the predicament but luckily I will neither get a 3 m rail or use a 110 pound load on it :)

The U-shape should, however, make it quite solid and hard to flex. At least I would have trouble bending a U-shaped rail but it should be able to easily support a meager 10 pounds in a 6' configuration.

But if it doesn't I can always use the regular Redi-Rail, which can be had in either 30mm, 45mm or 65mm width, which has been proven for heavier loads and is actually used in many video sliders.

Sorry for going utterly off-topic :oops:

I hate to break it to you... But 10mmx35mm (no matter what the shape) is not going to span 6' with 10 pounds dynamic load... Believe me, I spent 15 years in the architecture industry, I eat and breathe load capacity and deflection calculations. That's going to bow/bounce like crazy. Probably well over 1" (25mm)...

Let me put this in perspective for you... I just ran a deflection calculation for .5" x 1" solid aluminum (12mm x 25mm) spanning 6' (180 cm) with a 10 pound point load. I'm coming up with about 1.3" - 1.4" deflection... (33mm to 35mm) That's a lot and that's a larger solid section!

I'm pretty sure that the 110lb. rating refers to the load that the carriage will support, riding along a fully supported rail, which is how it would be used in most industrial applications. Of course, you could also decrease the deflection by positioning your tripods about 3' apart, and still support a 6' rail. Or mount a steel strut underneath, but that makes it a whole lot heavier.

I too have been looking at linear motion systems like these to use for a dolly controlled by the MX2 (just got the shipping prep email!). Any other issues you can foresee with something like this as opposed to Stage Zero system (alum. extrusion with a friction slide carriage)?

Just the normal issues of designing, testing and adjusting... The ol 'make it work!' factor 8-)

Hi Jay,

Are you still testing this motor? Are you planning to use it in future versions of the Stage Zero?
I've been trying to find somewhere I could buy it from, but it seems to be only available in the US, so far I only managed to find one company that would ship overseas, but the shipping costs were so insane that wouldnt be worth.

I wonder if anyone would know any other alternative, or somewhere I could order it from here in Europe.

Cheers

Have you tried servocity.com for the Dayton gearmotors? They have them in several different gear ratios for different top speeds. I'm not sure about shipping overseas, but I thought an internet based business would probably ship anywhere its legal to ship to. Here's a link to it.

Hi,

I did try, but they only seem to ship to US or Canada :(

It is so frustrating trying to get any gear at decent prices around here.

EDIT: Actually just found out they actually ship overseas, one as to fill a different for and wait for a shipping quote....lets see what they say ;)

I got charged $45 for shipping basic parts down under :-(

$40.78 shipping to Finland, a lot less than I thought.

Is anyone else using this motor? Is it right that this will run about 3x faster than the current Stage Zero motor?

Cheers

Yep and Yep!

Lots of people are using this motor. It will get you 90 inches per minute top speed (the title of this thread ;) ) which is approximately 3X faster than the stock motor (30 inches per minute).

Thanks for the testing info, Jay. This is awesome. I have looked at this motor, but always got concerned that the 1.3A rating could cause issues with the MX-2 which recommends 1A or less. Right?

Looks like I'll have to order one this afternoon.... ;-)

Great, I be ordering mine too. I'm assuming one can use the same pulley from the stagezero.

The motor should look and mount exactly the same as the original 8.75RPM unit.

We had that concern too so what I did was run it over and over again with a good load. This should in theory push it close to it's peak draw so all I can say is that it doesn't draw more than the PWM can handle because I couldn't fry it intentionally trying to fry it! :lol: Chances are these nameplate ratings both on the PWM and on the motor are conservative (remember we only rate our system at 15pounds but as most know it can pull a bit more ;) )

Yep. Same shaft as the stock motor.

Installing my new motor!!
Apart from calibrating, are there any other settings that should be changed?

Cheers.

The gearmotor with 25 RPM is also useable for timelapse? So only the MX2 should be calibrated for the new motor and everything will work as at 8.75 RPM and the only difference will be, that I can have 90"/min speed with it? or...

Should I buy the both motors to have nice slow and relative fast motions too?
