Hi Dave, The motors are Minertia brand by Yaskawa Electric of Japan and are model mos FA5S-CA11 and FA5X-CA31. I can't find any info about these on the web. The encoders are 1000 line with no index pulse. I have put some pictures up on my website - *http://tinyurl.com/6nf3sz **http://tinyurl.com/5w9942 **http://tinyurl.com/6c3btx *and * **http://tinyurl.com/5z82df
*As you can see, the board has a 2903 dual comparator chip which appears to take in A+ and B+ to one comparator and A- and B- to the other and send the resulting two outputs to the existing wiring. At the bottom of the board there are also the A+, A-, B+ and B- connections - presently unused and these are connected directly to the four connections to the lower part of the optics. This is an entirely separate piece to the LED and is apparently glued directly to the board. On the existing wiring, all the blacks appear to be grounds and all the reds are +5v. I am assuming that the motors are probably 12 volts but I'm not sure as I didn't remove them from the plotter.* * -- Best wishes, Ian ____________ Ian W.
