Dear sirs, good afternoon, initially the wolverine digitizer I bought, worked correctly. I did 50 scans. For no apparent reason, the point at which the roll receiving the film being copied started to function with rotation variation. This has caused a problem in the copy, the frames are shifted. I can only scan without rolling the film in Film Reels.
How do I solve this problem?

it sounds like the problem I had with my Wolverine, the take up motor is a pain in the neck.

Recently I have decided I not to use the take up reel but let the film drop in to a box and then a careful slow hand rewind from the box back on to the reel with my movie viewer.

I have done this with 50ft and 200ft reels perfectly well.

It's not ideal but I get jitter free scans.

I never use the Wolverine to rewind, it's useless for that too.

I have been through two original motors and one third gen motor but still find the take up is the weak point in this machine

You can see from my three videos the problems I have encountered with the take up motor
Wolverine motor failure

I can't offer a solution on how to fix the problem in a satisfactory manner, contacting wolverine is probably the best option, they may send you a new motor as they did with me, but 3 motors still cause me problems, I resign myself to using the box method from now on, and as I say, I get jitter free scans now.

There is no proper warranty on these machines outside of the USA.

Good Luck!

OP, no help. I had 2 Wolverines. Both broke after 15 to 25 scans of 200 foot reels. You are lucky it lasted for 50.

I'd look at the Wolverine as a disposable scanner. $300 divided by 50 = $6 per film scan. That is a bargain!

My Wolverine is 9 months old, I have now scanned in excess of ten thousand feet.

76 fifty foot reels arriving from a customer this week, I have just scanned 900ft of standard 8mm in the last two weeks.

My biggest issue is the take up reel/tension and that stupid clutch mechanism....... hence the drop box for the film, which has improved things...

Daniel when you say 'broken' did the two machines of yours just expire completely or was it the take up reel problem, but still scanning?

These machines will happily scan for hours using my box method, which I know is far from ideal, but it does overcome the problem of the take up reel..

Oddly enough IMHO.

This scanner is principally identical to a sprocketless projector,which had been perfected since 60's-70's. (My little Fujicascope sprocketless projector never had the steadiness issue,at all)

Then all in sudden we can no longer repeat that same level of success anymore. [Roll Eyes]

A very common problem with a lot of us. This is why I don't use the take-up spool either.
