Neet, I need to look for that group.
My old HF horizontal bandsaw couldn't hold a blade. After all sorts of
twiddling with it, I finally got around to getting a new blade and it
hasn't thrown it since.

There is a 4X6 bandsaw group on Yahoo Groups that specializes in tweaking
maintaining and improving the cheap import bandsaws. They have a very good
tuneup guide in the files which will walk you through all the maintenance
adjustments and upgrades to get your saw back in service.

nah! she did a semester of logical reasoning, much worse!
My peabrain finally woke up to the facts of bandsaws.
Last time I had this not only were the bearings gone but also the crown of
one of the wheels
was completely eaten away by shavings caught between the blade and the
crown.

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.

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 en

How are these customers dealing with a stalled stepper, or is there any
limits built in?
I know you should never have a stalled stepper, but you still need to plan
for it anyway.

I have been looking at the gecko drives, they are 10x microstepping, which
seems overkill. They do have some decent

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

I could not find a wiring diagram of the devices connected to the Mesa 7I43-U-4
card at GantryPlasmaMachine. Config files yes, schematics no.
That is otherwise a GREAT wiki page! Thanks!

Just a bare 5i25, or using daughter cards?
You ought to be able to do it with a 7i76 and a 7i7
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.
