Yep, I have used steppers, servos, optical encoders with EMC etc etc in the
past, however, on this particular device, I am not going to try and hack
the mechanicals apart to start changing stuff. It's a high quality bit of
military kit that has presumably worked well enough in its previous life,
it just needs some suitable control system putting on it. I've been
running stuff on EMC for decades as you probably know, so yeah, I know what
it can do. As it stands, it is fully waterproof, with all stainless or
aluminium parts (yes, I am aware of the issues mixing stainless and
aluminium) and the highest quality waterproof Amphenol connectors, I hope
to be able to leave it as it is.
A 2 pole resolver will typically be good to 5 minutes of arc, these on here
are some of the nicest I have seen, the military are not known for cheaping
out on their kit! I fully expect them to acheive that level off accuracy
with the Mesa board.
Touche`. That is about the accuracy I'm getting with a clone BS-1 I
CNC'd a year ago. Worm in the encoded gate motor into worm drive in the
BS-1. Too slow for active machining unless EDM'ing something. Great for
holding tools at add angles to sharpen them with a CBN wheel. Also too
heavy and too tall for my G0704 to carry comfortably. Should have
started with a BS-0.
Cheers, Gene Heskett.
