Hi All,
I am working on a project that regulates a sewing machines stitch length in proportion to the speed that the sewing machine is moved around on a quilting frame.
Has anyone on the forum done this?
For this I need some really simple but reliable rotary encoders for the X,Y direction of the frame that can output pulses around 500PPR or more. PWM output would also be ok, as I intend to interface the encoders to a Picaxe to provide a semi proportional resistive output. (I have that part worked out)
There seems to be plenty of rotary encoders out there, but most are fairly expensive and of the quadrature or multiple grey code type. I just need a simple slotted disk type incremental encoder that doesn't care about direction.... just square wave pulse or PWM output relative to rotation of any voltage but of course around 5V pulses would be good.
I'm sure the vector maths for diagonal velocity shouldn't be too difficult, but any help there would be appreciated as well.
Looking forward to your replies!
Regards
Maarten
