I'm considering updating my Sheldon lathe to the 2.9.8 arm64 trixie
image, currently running a bookworm image RodW made for me a couple
years ago.
Does the new 2.9.8 pi clone image still support the creation of slower
threads?
To conserve realtime-preempt performance, all manual i/o in .hal files
has long been running in a separate 200HZ thread for the last decade+,
based on I can't twist a 100 PPR encoder dial even that fast. This was
originally done to get acceptable performance with the slower pi3b.
I have created a backup of only the user 1000 stuff, using a 5 pack of
4Tb SSD's in a software raid6 configuration & a bananapi-m5, well over a
$kilobuck of parts, but w/o the small monitor which draws about 8 watts,
it idles on 14.5 watts and runs the backup at 19.6 watts peak. Speed
wasn't really the target, low power was more important, but it only
takes around 35 minutes to backup 8 machines here. I can describe it so
you could build your own but pretty it isn't. Works fine though. You
will need a 3d printer. And around $1800 to dup what I have. I can
supply the OpenSCAD files to make the printed stuff by PM.
My way of saying thank you for all the support over the last 24 years
since I retired.
Cheers, Gene Heskett, CET.
