Thanks for the discussion on stepper motor performance. We have all
confirmed that the limit in speed lies not in the software, but in the motor
and its supply voltage. That's what I wanted to be sure about.
I want to start another subject: G71,G72,G73 cycles for lathes.

Have you considered the possibility of using a remote brake?
What I suggest might be a gear on the motor shaft meshing
with another gear to the side of the motor - this gear to be
on a shaft having a normal type of electrical brake.
Alternatively use toothed belt pulleys and a belt instead of

Kirk,
Do you have a #0 tool position? With an incremental counter
going from passing the #0 tool, just check the increment, and if it's
equal to or larger than the median go one

What do they do?
I get the impression that they are lathe roughing cycles (turning,
facing, boring?) If so then the same thing can be easily performed by
simple loops

Do you guys have any clever ways to mount Mesa 5I20 I/O boards to a 35
mm din rail?
I have some plastic din rail clips from Winford, but the holes don't
line up. Before I reinvent the wheel, I want to make sure I am not
overlooking an easy solutions.
Thanks,

Jon, what's the problem? Don't you have the entire upstairs still

Thanks Andy, Kirk, I have now sorted it out - unfortunately,
I've also found a fault on the board so it will probably
have to go back bummer..

Hello Ian, I've tested this board before (and several of it's numerous

absolutely dumb for a 3-axis machine IMHO, the solution is obvious enough to

I won't claim clever but I cut the clippy-bits off of some DIN

boards to the MDF.

I mount PCB's (Like MESA card) onto a piece of Perspex. Scerw that to a
dummy terminal block so it mounts onto the DIN rail.
