How feasible is it to use the mesa 5i25 in a similar way to the universal
stepper controller? IE.. Use hardware step generation + encoder feedback?
Another ignorant question, why is the industry so inclined to isolated IO?
vs single board designed systems where everything is layed out properly.
Isolation is about protection of low voltage circuits that cannot
handle any spikes outside normal ranges
and the voltages inherent with electrical noise in a working system
which could easily be up to 1000v or more.
It also removes the ground loop that add/subtracts from your signal.

Take a standard Universal Stepper Controller, and get it working with drives

I know you should never have a stalled stepper, but you still need to plan

Hi all,
I have a cheapie horizontal bandsaw that has performed decently well
for 10 years or so and just recently started sheddinga the blade after a
few turns.
As far as I can tell the blade works its way off the non-driven wheel.
I suspect the guides (ball bearings) are at fault but will

at least one of the wheels does not run perfectly parallel to the other
wheel anymore.

Dave,
I don't know what kind of bandsaw you have, but I have several bandsaws
and all of them have a means of tilting one of the wheels (usually the
non-driven idler wheel ). If your wheel bearings are good, then it is
likely that your one wheel needs to be tilted to track the blade.
