After having the probe set up for awhile... I discovered that the relay
system has inherent problems... sometimes it jitters and messes up the
results. This means I need to add some serious debounce to the probe.
already had a setting in the LinuxCNC setup... but I needed something
Digital Probe Circuit #2 - Using a microprocessor. - March
By using a microprocessor, I could change the delay as needed and
possibly add in other useful features. One added feature was a beeping
sound to indicate contact, and another was to play a short tune when
started to let me know the new circuit was functioning properly.
And of course... just because I thought that would be a cool
feature. :- )
Remember to always be safe!
A Public Service Announcement from
The 100 Year Old Pulley Project
My friend Kevin came to
me with a problem... his dad had a lathe made
in the late 1800's and over the years, the main drive pulley became
out-of-round and wobbled somewhat. He asked me if I could help get the
machine back to a smooth operation.
