Jonathan I've had to correct stuff you made because the fucking things weren't square or correct so don't give me that bollocks.!!

Also if your going to quote me then make sure you quote the whole fucking picture not just what you want to make fit.!!

On Jobs that run non stop for 10-12 plus hours like litho-pains this could and has been for some slaved stepper users disastrous often resulting in not just in in-accurate work but stalls thru accumulative error over hours.!

Both work and won't argue that fact but I know which works best.!!
