If the technology is too old then what should I consider as a replacement, preferable still on the spindle rather than belt driven from the spindle. Thanks, Mike

You only want one of this and a one slot disc as Mach3 and 4 cannot read a multiline encoder. I can look the part number up tomorrow if you want ? tried checking past orders on the RS website but it's in a continual loop

16 forum posts	Thanks John, That would be a great help and from what you say I guessI could use the plain back of the existing disk and just cut a slot. ?how wide a slot? Thanks, Mike
