I would say so, yes. What you are describing is pointing exactly to that. That’s also why your 12v motors keep burning up. 

 

If I had to choose, I’d go with the 15rpm motor, I’m going to assume it’s faster due to the smaller holes. Can always turn it down, can’t turn the 5 up. 
 

if I were you, I’d also order a spare speed controller, I sent a link before. They are like $7. It’s not worth the down time if you have that issue later on.

 

The 5RPM actually seemed too fast for me when I had it at full speed, the powder went in way too fast. I thought I saw a post somewhere on here from you saying that a higher RPM won't be able to slow down too much...that it will stop or something? Might be misremembering that.

I ordered the speed controllers...2 of them this morning. The relays you mentioned from Omron are also coming in today. Looks like most of the internal parts on this machine should just be changed.

This new shaker says: 

its 24V and 10RPM. 
 

My previous shaker said 12V 3rpm. 

That is actually the exact one that was in my shaker. So does it sound like putting a 24V in will resolve these issues?

One more thing I just noticed...the slapper seems to be going much faster now (at 25%) than before. It's like I have it up to 50% or higher.

Both of those run on the one 12 V power supply.

  The box back in there in one of the photos I sent.  You say both are shutting off at the same time when you turn it up to high? or is it just the slapper? 

 

If so, Is it possible your motor you installed is touching the metal frame ( the tabs on the motor)? 
 

if it’s only the slapper and the duster continues to function, possibly the speed controller.  
 

have you taken the face plate off yet?( with it unplugged of course) Might be a loose connection. 

So right now, the duster won't work at all. No motor sound or movement when I flip the switch/rotate the dial. But when the switch for the duster is on and I turn the dial to around 50%, the slapper stops completely. Turning the duster switch off or the dial down gets the slapper going again.

Also just now, I realized that when the dial for the duster is up JUST enough to stop the slapper, the slapper moves slightly every time the take up reel pulls the film.

I will have to check the motor after the work day and see if anything is touching. It was working fine until now so I'd be surprised if thats happening.

Glad it’s working, good to hear. So the bigger holes as described did the trick?

Can't edit my last post.

Now, when I turn on the Duster and rotate the dial, the shaker stops when I get up too high. WTF is going on with this thing. 😠

So it looks like I spoke too soon. The new motor stopped working again.

Something weird happened at the same time though...the shaker stopped as well. But then when I flipped the switch to turn off the brush roller, the shaker began working. Does this sound like the wiring that you mentioned in the previous page could be the main problem with this whole machine?

Here’s some cheaper ones:

If your cool with silver, they are even cheaper like $16.

I don't understand how you run a business, modify all this stuff, and answer people's questions consistently. Do you have 36 hours in a day while the rest of us have 24?

The new shaker of mine has locking wheels. The old one had legs you put down with regular wheels.Kind of like to level the machine and lift it off the non locking wheels. The new one has the holes where they are on the old one, but no bung or feet.
 

I lifted the old machine off the wheels with those levelers, and put a turkey pan in there. It easily holds all 5lbs of powder from my hopper, easily 8 lbs. 
 

the new shaker doesn’t have them, but I will add them, or something similar to use a similar pan.  I never used the stock pan, it’s too small. If time crunches occur, I’ll find a wider thinner pan. 
 

the wider pan is awesome, because there is literally no spillage and no overflowing. Every 30 minutes to an hour I just walk over, stop the slapper, pull and dump the pan back in my hopper and turn the slapper back on, takes like 10 seconds. 
 

that’s how I did it anyway, in both the minI shaker and my home made cart build.

 

a pan like this- or a metal pan with the handles on the side is what I use. 

Yea your new machine sounds like the one I got. I was wondering how you fit a pan under there. I will test some things out because it is pretty annoying how small the stock pan is. Difficult putting the powder back on top with it too.

I have no idea to be honest...at this point as long as it works, I'm good. Only problem I have now is anymore than 1lb of powder, and the tray at the bottom fills up. Wish there was a way to have the powder automatically recycle. I'm sure I could figure out a way if I had the time to learn the mechanical/electrical stuff.

Sounds like a good plan. As for the motor, I'm not really sure. I mean i know mine does make a different sound under load, but it still spins the same speed as far as I can tell. 

So far, 3 days in and it's working. Strains A LOT at around 40% speed but it hasn't stopped. Yet lol

If it were me and if I’m in this same position during testing, likely I will drill the holes to one size larger for the middle row only. And keep adding rows until it works or doesn’t, then go up a size. If I need to tape off rows ( like the first one) I will. 
 

if none of that works I’ll remove it altogether and make my own powder box like the cart build. 

Ok so I just finished this major pain in the ass (got taken apart very easy but putting it back together is terrible). Before reassembling, I drilled larger holes on the middle 2 rows, but every 3-4 holes. Total of about 15 hole. We’ll see how this does and I’ll either drill more or tape off like you said. 
 

As for the motor, I tested the old motor by just gripping the bar with my fingers and it strained pretty easily. New motor, couldn’t slow it at all. So either the last motor was bad when I got it or it became bad with use (just about 4 hours of use though)

Now testing the new motor, it also seems inconsistent when there is powder in there. The sound goes deep and high back and forth. I think time will tell for now how this will hold up.

I received the new one today. Did yours come with a film holder for the printer? 
 

this one is different, it uses solid state relays, so no worries on those if yours have SSR relays. It also has less holes but no tape and a few other variations. Overall a better machine than my first one. 

Yes mine did have a film holder for my printer. 
 

I’m taking it apart again to replace the motor. Take a look at the holes on mine...I think this is the problem. The holes are too damn small and not enough of them for the powder. When brush gets stuck, I stick my hand in there and the powder gets packed in very tight. I think I’m going to keep having these problems unless I make the holes larger. These holes are probably 1 mm wide.

This shows the tape, and the metal plates to remove to drop the whole unit down. once you remove those plates and slide them out of the way, it's the only thing holding the whole thing together. 

I’ll try putting a few larger holes...I was thinking about that since the powder just piles up and blocks the brush from spinning. I’m sure even with a new motor it’ll be easier on it. Mine is a solid piece of steel so I will have to drill through it. 

I’ll buy another 5rpm motor and hopefully the one I got was just a bad one like you’re suspecting. Out of curiosity, did you replace the motor alone? It was impossible without another set of hands.

I also just saw your video (not sure what’s up with this website but on my computer, it gives me an error. It’s only loading on my phone). I run it pretty much at the same speed as you....would be great if I can load 5lb like you do. When the original motor was successfully working, I had to reload the powder every 30 min. 

2 hours ago, johnson4 said:

If your not getting enough powder, try opening up a couple holes on the bottom ( poke holes in the tape near the center). I did that, I like my U shape to be full of powder, it adds weight and pulls the film down better, makes sure everything is coated well, and overall creates tension to smack the powder off better. . Obviously if you do that you'll run through more powder, which is why I added the box on mine. 

What tape are you referring to? You mean the metal underneath the brush roller? 
 

I feel like my brush is a bit too large which is also a problem. It’s basically touching the bottom and only has about an inch on each side. 
 

I’ll buy another motor and see if that resolves everything. I did see a lot of negative reviews on Amazon...people saying that they can pinch the bar on the motor and stop it. I was trying to find a different brand but no luck. 
 

Looks like another few hours of frustration. Having minimal tools along with no room to screw/unscrew everything is a huge pain. 

It looks like when the powder gets piled up on the side of the motor, that's what stops it. I pushed the powder all to the other side and it worked fine. All to the motor side and it almost immediately stopped.

Here's how it sounds:

Sorry guys...wanted to test further before I waste anyone's time.

Yesterday, it worked with no issues, but I didn't fill it up with powder. Today, I filled it up with a full 2.2lb of powder and it began slowing down to a complete stop. I turned that part off for about 10 min then started it back up and it began working. It looks like the extra powder is the issue.

One thing to mention....the motor I bought from Amazon does sound like it's strained even with no powder. Before soldering it or hooking it up to the brush roller at all, I tested it just to make sure it worked and halfway through it sounded like it was straining exactly how you're describing it. So this sounds like it could be the issue correct?

I've been pretty busy this week so I haven't had the chance to swap the wiring and see if that makes any difference. I will be ordering the relays and swapping them out while I do this step as well.

Actually listening to it now with little powder, the straining doesn't sound as bad. It does strain a lot when I put in a lot of powder though...it's pretty clear that the powder just gets caught between the brush roller and the metal plate causing it to do that. For now, all I could really do without it stopping is let it run at 50%-100% and put in no more than 1lb of powder.

You could if you cut a hole in the side, but it isn’t necessary. The 5rpm motor I received can’t be stopped by hand and handles 5+ lbs of powder in the hopper. 
 

likely it’s just a defective motor, or it was installed slightly off center causing it to bind or something. 
 

mine originally did similar , it would just stop working after some time, and work again later. It would slow and slow until it didn’t work until I let it sit. Also, half of the rotation it sounded strained even with no powder. The motor still sounds like that when nothing is connected to it. The replacement motor didn’t do that and worked fine, for me anyway. 
 

so far the main issues I’ve had with the mini shaker:

1. Duster motor

2. Poor quality relays causing high amperage draw and failing. Probably one of the reasons others experience failing heating tubes. 

3. The take up roller walks, so I put a guide in it. 
4. the slapper blade is getting damaged by the bolts holding it to the bearings, but in a way that doesn’t affect functionality. 
 

Haven’t had an issue since, yet. It’s ran for maybe 1000 hours so far.

Bad news. That part stopped working after 3 hours of use today. I have no idea what’s going on. Any ideas what could be causing this and if I need to replace something else? Sorry to bug you about this. I depend heavily on this machine and this has set me back severely. 

I turned off the powder to the "duster" and turned it back on about 30 minutes later. It began working but very slowly but then it slowed down to a stop after about 10 seconds. I'm not sure if this is a problem with the motor I bought itself or if it's something to do with the switch that turns it on. The stock one acted the same exact way so I'm thinking something is causing the motor to go bad.

Awesome! Yea you can take it all the way out, but it’s a pain. 
 

yea, I as well think it goes faster than 5rpm. Hopefully it goes well.

Alright guys I did it....it was a HUGE headache because of how tight the space is around the brush roller. I'm not sure if there was a way to completely take it out, screw everything back in and then put it in. I didn't seem like it. But it looks like it's working.

I ended up getting the 5RPM one (although I'm pretty sure it does way more than 5RPM) because it was going to arrive sooner. I'll be testing it tomorrow and see how it goes.

Just use higher RPM 10 if necessary. More is good, and i don't think any significant amount diffirence there will be. 

Most likely when you want it to go slower, it just lowers DC output. So RPM also gets low. If you can go %50 with 3 RPM motor, with same conditions you can go to %30 with 5 RPM. If you want to put more powder and go lower speeds at same time then go 10 or 20 RPM.

Got it! I went ahead and ordered the 10RPM one. I appreciate both of your help. Let’s see if I can actually put it together now.

Are you talking about the Powder drum in the mini shaker? Mine too, I replaced mine with a higher RPM motor. I put a box on mine and fill at least 10X the amount of powder it was designed for, and it never actually failed, it just was poor quality to begin with and would " struggle" half of the turning radius for some reason or another like it was binding when empty. 

 

remove all the powder, and on the underside there should be several screws ( maybe 4) where the film goes into the shaker, those take it off. Then proceed to disassemble the small powder box on top until you can get to the motor, which for me, was all the way. I think on the underside there was a few more bolts but it all took maybe an hour from start to finish not knowing what I was doing. The stock motor is a 3RPM 12V motor. 

 

This is the same motor that's in there: https://www.amazon.com/gp/product/B071XCX778/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 

its the 12V 3 RPM version stock on the mini shaker, But I put in a 12V 5 RPM version for a larger range of speeds, and a bit faster when needed. Works great and has been. The original was replaced almost immediately before it had a chance to fail. 

 

You'll also notice, they used clear packaging tape to cover up 90 percent of the holes where the powder comes from. DONT peel that off, you can open up a few more holes if you need more powder, I did and all has been well. I also "sift" my powder before filling, so no clumps clog the holes.

Wow you know everything lol

With that 12V 5RPM one, would I be able to use very slow speeds without the brush getting stuck? With the stock one that came, if I put any decent amount of powder, I couldn't set the speed lower than 50% or else the brush roller would stop.

The "dusting" mechanism (the brush rolling part) suddenly stopped working yesterday. I think it was my fault...I may have put too much powder in there and it got stuck while it was rotating. It was weak to begin with when I first got the machine...I couldn't use low speeds if I had half of it filled with powder so I'm not sure if it was bad to begin with.

I'd appreciate anyone that can help me figure this out. At least where to start...I have 0 knowledge of electrical repairs.

Google "Epson SC-P600 service manual" and see if you can find a PDF. I believe service manuals show a basic illustration of how it can be disassembled.
