To feed or not to feed, that is the question
DarkRipper - I'm not sure the best way to answer that question. I don't want to say every loader ever shipped is perfect (they are tested 3 times in 3 different ways, but even then things vary). But it's not an "issue" with the vast vast majority of loaders. I talked to Tom last week and I think he said they had 6 Spires in over the last 3 weeks (one was for a bad sensor, one was for a broken piece of plastic, one was for this "over spinning" issue, and I can't remember the others). We've sold a lot of loaders, and we're really happy with just how few issues we've had. Any loader, Spire, Rotor, Z2, etc. that relies on motors, plastics, electronics, is going to have varying degrees of tech support required. I can't speak to their rates, but I know ours are pretty low.
There are a couple issues at play, as has been pointed out but I want to summarize them and give some thoughts on the product.
The Spire is designed to give priority in feeding. Both the mechanical operation of the Spire (spring + flexible fingers) as well as the electrical (motor tension + shot detection software). In sense, if you had to choose between a loader that jammed frequently, or randomly jammed, or a loader that tried to feed (with no adverse affects to paint) we'd chose to have a loader that didn't have jamming issues. This is a philosophical approach to what we did at the hardware + software level, combined with respecting existing patents out there.
If anyone is having this issue, the fastest way to get help is to simply call us: 631-617-5346.
The Spire gives priority to feeding.
It wants to feed when it detects a shot from the G-force sensor, and if it doesn't "feel" any paint after you shoot, it keeps slowly spinning to make sure you never end up in a situation where you have paint in the loader, but none in the gun and your gun won't shoot because the eyes don't see a ball, and your Spire won't feed because your gun won't shoot.
If we were using a paddle without springs + flexible arms, the over spinning wouldn't happen because the paddle would hit the ball and stop after the ball doesn't feed.
But since the springs + flexible arms effectively allow the paddles to slide under the paint to clear potential jams (and keep feeding plus be soft on paint) there is a balance in detecting the precise point in where the Spire is loaded compared to when it should try to keep feeding. On the plus side, the only downside is wasted batteries and annoyance (rather than the alternative of breaking paint or jamming up). But this extra spinning is not something that should be common place or you should have to live with -- that's why we have settings there in the first place, to make a quick adjustment to most likely fix the issue and why we have tech support, to replace any part that isn't functioning properly.
Also, keep in mind (as I'm sure most of you are aware, but just putting it here for the record) that if the batteries are low, or a poor quality that puts out too low a voltage (even when fresh) then there will not be enough power to keep the motor from spinning when loaded.
Ultimately, the point is that there are thousands of people out there now with Spires that don't constantly spin when loaded. If your Spire is spinning too often, that is a problem we want to fix for you. I wouldn't ever believe someone if they promised their entire product line has a 0% failure rate. There are thousands of individual Spire users who have 0% issue rates, but naturally from time to time there will be issues.
With some loaders the issue the manufacturer needs to fix is they break paint, or they jam, or the eyes stop working, or the motor fails, or there is a bad board, etc. etc. With the Spire, the issue that comes up from time to time is it tries to feed too often. It's not the worst issue to have, but like I said it's not something anyone should live with.
If it happens, give us a call. We're eager to take care of it.
