    good scanning on a printer

    According to the coder this was done on a 0.1 mm grid, and could be taken to a 0.05mm grid with half steps. It seems to work reasonably well as a scanner, but what do you guys think?

    Hmm, i can see it would be useful for copying keys, though how useful a plastic key would be I'm not sure.

    It's sort of like the original scanner i had 25 years ago (possibly longer) for my amstrad pcw. You attached a little scanner to the dot matrix head of the printer and it scanned pictures line by line.
    This is a slightly updated version of that.

    If it could be configured to produce a solid rather than a hollowed out shape, could be quite useful - I assume it's cheap :-)
    Anything more than $100 and you can forget it :-)

    They have addons for scanning objects.

    haha. It would be useful for robbers, if they can get acees to one's keys. scan them and put back, so no one notice. Print a plastic key, won't last long but should ne enough to open the door, steal what you need, and cllose it back, maybe with second printed key.

    The key was just an example of what can be done with it, I am reasonably sure that it as more uses than just that, and the reason it's not automatically put together into a solid model is because the guy who did it has skills more to do with the practical side of machining than well, programing. The idea of it is that you should be able to scan basically anything and to relatively high precision (as high as you are capable of printing, pretty much by definition almost) although obviously with limitations regarding undercuts and such, and something are obviously going to need multiple scans and re-combination in some modelling software, because once again, this guy is a mostly a machinist. But hey, it's free, any printer can be configured to do it.

    It's free, any printer can do it, though results will vary based on how well the printer is made/calibrated.

    ah so it's an instructable ?
    Missed that thought it was another kickstarter project. I really have to start reading all the words :-)

    Well in that case I can think of a number of uses. was a guy recently(ish) who wanted to make custom case inserts for guns - this would be ideal for him.
    Guess i could remove the right motor and mount it there.

    It is a good idea, just reminds me of my first scanner way way back when.

    One thing does concern me. Instead of the proble moving up and down, it looks almost as if it forces the bed up and down - that can't be good for the bed.
    Or does it somehow link to the printer and move the bed down untill the probe is clear ?

    Is there a web page or something useful we could look at ?

    that's because the bed is the z axis, like the ultimaker.
