I have been asked to make 30 spinnaker anti-chafe trumpets for a fleet of race yachts. I confess I am not desperate to do it, and the timing is quite tight (they need to get to the yachts when they arrive in Rio, currently they are 300km north of the Cape Verde islands. It occurs to me that having

Greetings I have an XY stage with Heidenhain linear encoders and BLDC motors on its screws. The encoders have built in interpolation giving a 0.08 micrometre resolution. I have a Mesa 7i39 on its way. There was a lot of BLDC work done by Andy Pugh around the turn of the year but so far as I c
