I can't qualify it as "rarely-used" here, Andy. I don't have a hal
file that doesn't have some outputs that are there just to watch
You run "Halshow" all the time? Even when the machine is running normally?
Not halshow, but halmeter's. Sometimes as many as 8 when I am tracing my
often broken logic. But when its working, the stub stuff rarely gets
excised from the hal file when its working, but the halmeters don't get
started when I no longer need them.
In working on those chuck locking collar's I had 2 problems today.
Running the G0704 to drill the stuff in the rim preparatory to fitting a
5mmx.8 draw screw to tighten it on the edge og the spindle flange, I had
it positioned and touched off at the centerline of the screws, bore, so
I took a wild guess at how deep the screw hole should be, guessed 1.5"
because I had not found when the er-32 nut holding the drill, was going
to hit the rim and chew it up. g1 f2 z-1.5". And when I hit the return
key it drove z down to -1.5, but it drove it at about 50 ipm, moving the
work piece in the vice, so I had to start over, locating it in the vice
& making sure it couldn't move again. When I had restored its position
in the vice, and touched off a new x0y0z0 position, I uparrowed in the
MDI history and reran it. Worked perfectly. Murphy? DamnedifIknow.
Then I took the ring, whose gap I had not sawn yet, off the mill and
chucked it on the lathe from the inside, and proceeded to make first
swarf. I had not reduced the error and ferror settings below 10.xxx if
the .ini file yet. But I fooled around, driving it by hand for close to
2 hours spindle run time, without a single joint error.
But one thing's bugging me, this damned pi doesn't always ack the key up,
so the axis I needed to bump a thou, keeps on moving at creep speeds
until I hit and release a key. Any key. It like the keyboard has its
name in the priority list at a very low priority position. Looking at
the usb stuff when it has nothing else to do.
Anybody know anything about that? It's been an intermittent since day
one. I have several keyboards, and when its of a mind to make a problem,
changing keyboards has never helped, as is a reboot will often clear it
up All are usb, and if it being a problem, switching from wired to
wireless doesn't effect the error rate.
Clues? I've tickled it extensively without a finger to put on it.
Cheers, Gene Heskett
