You may be surprised at how fast you'll need to move if you want to complete a project in a reasonable amount of time. A typical embroidery machine does 800 stitches/minute or 16/second. If a particular pattern needs 1/4" per stitch, that could be 4" of movement in a second. That lead screw is going to really be moving. Now obviously you can slow down the stitches per second, but you still have the synchronization of the XY movement to the switch. I don't think you'd soley want to perform your movements soley on if the beam is blocked. That's going to make your stitch rate extremely low.Quote

Looking at the sewing machine I have access to. It would be easy to attach an optic (beam break) type sensor, to delect when the needle was up, and hence to calculate the rate at which the XY head needed to be moved.
The speed of the machine is controlled by a foot peddle, which appears just to be a variable resistor.
So technically it appears to be possible to build some hardware, using the standard reprap eletronics, i.e Mega2560+RAMPS + 2 x stepper motors, to drive an XY head (I suspect that lead screws may be the easiest method as high speed movement doesnt seem to be required)
I don't think your embroidery quality would be very good if you use slicer. I've only had limited experience with a commercial sewing machine with embroidery capability but the quality of the embroidery software will have a huge impact on the quality of the final product. With 3D printing (or CNC milling or CNC laser cutting or whatever...) you don't care a huge amount how the product is laid down (additive manufacturing) or removed (subtractive manufacturing), just that it's done so completely. With embroidering, the stitch pattern and length of stitch can make a big difference. Slic3r would basically just create a pattern where the thread covered the whole surface, but it wouldn't be tight especially in large coverage areas and you'd see through it as the stitch would be long.Quote
But it looks like, if I designed a 3D model that was 1 layer thick, that Slic3r etc may be able to generate a path, that would effectively turn this into an image in embroidery

Maybe you can use one of these ideas to sense where the needle is:

Not in the biz, but have done some embroidery. My wife has a Janome MC10000 which at the time she got it was kind of "top of the line" sewing machine/embroidery machine for the home user.Quote

I just watched a video that had some commentary on stitch rate 960/minute, are you in the embroidery biz?
