Hi folks. I’ve got trouble with assembly of my ROKR dream gift factory. The A2/A10 assembly that slides thru the slots in D1 is supposed to control the up & down movement of the box covering the gift. On my build, the box only raises up and won’t come back down. After watching two assembly videos and reviewing each step multiple times, I can’t see what I’ve done wrong.
I’ve actually bought and tried to build the kit twice. The first build froze at the stage where one first fully tests the functions described in Power-on test 1 on page 9 of the instructions. On the second kit, I started reviewing all functions more closely/sooner in the build, as soon as I completed Step 4 on page 6.
I was careful to ensure that the M5 lobe was in the downwards position as it installed thru H3, as was the sliding A2 assembly. It appears to me that the M5 lobe extension that fits thru H3 is supposed to raise the piece - and that works fine – but the A2 assembly won’t lower and I don’t see an assembly function that would do so.
Make sense? Here are several photos that hopefully show my problem area. Thanks for any help!
If Joe is correct, you appear to be missing a couple of misses or maybe have them in on the wrong sides. I am not viewing my instructions at the moment. Hard to look back between the two pics (yours and Joe’s) to tell which piece…but they definitely do not look the same.
Hello, the inner side of this area needs to be waxed and lubricated. This part relies on its own weight to slide downward, and excessive friction may cause it to get stuck. Please try applying a small amount of wax for lubrication.
Thanks for the responses! Here’s a pic of both, with Joe’s on top. After review, they appear the same to me. The reply from CustomerService informs that the part relies on its own weight to slide downward, and I was also wondering about that. I’ve re-lubed both sides, no luck yet, but it may well be that I need to loosen the P13 washers up a bit and exercise the part movement a bit. Will try that later and report back. Thanks again for the assistance.
the one gear I circled: one looks straight and one is almost crooked?
then there is a piece I circled that looks completely different. I dont know, just an observation!
So @Tom_Baylis, first of all, welcome to the community!
As @jeanneL has pointed out, one of your gears seems to be not aligned properly. I’ve noticed through the four kits I’ve built so far that this kind of thing usually happens under one of the two following scenarios:
a) You were supposed to push that piece as far as possible, and you didn’t do that (so, you need to push it further so it’ll match the position in the other picture)
b) There are screws involved; if the screw is not properly aligned with the hole it’s supposed to get into and you keep “screwdriving it”, since the screw it’s not finding its way through the hole, it’ll start using the piece in front of it as a force to push the “screwd” piece to the back, which could result in it breaking or colapsing
Does that make any sense to you? I don’t 100% remember this step from my build as it is, but I do remember also that further in the build I was testing the electric system and that part won’t come down 100% as well, so I had to kind of “push it down while the system was working until it found its proper place to move up and down properly”. But I don’t know if this would be your case.
Thanks for your good observations. The large gear you mention has a bit of flex play, which is why Joe’s seems crooked. In my build, the meshing with the adjacent smaller gear to the right is smooth & fully functional. With the other difference you circled (good eyes) with part K4, there is printing on only one of two similar sides. When my mechanism is moved 180 degrees, it looks the same.
This was my problem, and solution - thanks! Finding out that the piece uses its own weight for downward motion was the key. Cleaned all surfaces, re-waxed and I added a bit of dry white lube and it works like a charm. Thanks!
Problem resolved, thanks to everyone who replied. Learning that this component is supposed to be able to slide down on its own was the key. Cleaned, rewaxed and lubed, and it works just like it should.
I didnt know which belonged to who! I am so glad you got it fixed. Glad you reached out for help too. Customer service and Robotime are both really good at answering quickly.
if none of us can help, they are there!
Sorry, I’m just now reading your question, but luckily you found a solution. Waxing helps make moving parts run more smoothly. I wax all the pieces that move over each other, even if it’s not indicated. Hopefully, the rest of the build goes well and you don’t have any further problems.
Also it can help to sand the back side of the part that falls down. I sand all the surfaces that has friction and then wax them and it works great. Also don’t forget to wax the gears if it says so.
It may be that the bushing is too tight, preventing it from dropping down on its own.
I noticed that the wood board seems to have been treated with some kind of grease. If possible, wax is the best lubricant.
Thanks!
