Hello All:

I have quite a list of small bugs and problems for next release. Please
hold off on any feature requests until after next version. I was only away
for a wekk, but the volume of mail is very high. Most are feature requests,
but many had some additonal bugs.

BTW: THC G28 bug will now be investigated further. I was waiting for
confirmation, and now we have 3 sepatate systems showing this bug. ( more
than 1 requires action.)

Thanks for your patience on these issues. I now wait for copnfirmation on
all bugs except the most serious. This is necessary as I recieve at least 5
bugs a day with 4 of them folling up with a "Never Mind..I Screwed up
report. ). To save much time I now wait for a second report before jumping
into the code. A single bug can take several hours of tracing to find and
I've spent hundreds of hours tracing non-existant ones.) This is not a
rebuke, I just wanted to make sure you guys know I'm not ignoring you on
bugs, just trying to prioritize the available time to be more efficient.

I have at leat 10-20 items for next weeks release and am working on them.

Thanks,
Art

All Step/Direction spindle bugs V7.2 lathe

The problem I have, is although they are being generated the steps out
are reverting to some arbitrary value. Although Mach2 seems now to be
storing the value in XML, what it puts out isn't what I set. I can get
my 10V max out if I adjust motor settings, but on closing Mach2 and
restarting, although the values in steps per unit & velocity haven't
changed, max output voltage is down to 6V, re tune and it's back to
10V for that session only.

Can you also look at spindle & coolant toggles - sometimes
spindle fails to switch on - no LED and pin is not toggled. It seems
to happen more if you toggle coolant on first.

A long outstanding bug is it's impossible to set flood on extern2 and
mist extern3 - they always swap back.

Press Reset on and off then Spindle won't toggle.

Use spindle feedback for speeds has no effect using step/dir.

Requested speed and actual speed can be way out but no correction to
step rate is apparent.

Also V7.2 still reports itself as V5 in about screen.

Thanks Steve:

Does the spindle speed work correctly in Mill on yours. (I was using mill
to troubleshoot this one, my mistake..)
Speed correction is only turned on in G32 move. This is independent of
step/dir or pwm.

The rest are on the current list...

Thanks for the bugs, clear and concise as always..

Yes - works fine on mill, just been and tried it, it's within + or -
.05V on 20 attempts with lathe hardware. Reset toggle doesn't affect
spindle on either.

Speed correction is only turned on in G32 move. This is independent of
step/dir or pwm.

Ohh - anything stopping this being an option at all times?

The rest are on the current list...

Cheers!

No problem :)

Having Spindle correction at all times...Hmmm... Perhaps. The problem is I
use the actual feedback when a G32 is started as the start speed and
correction is done during the G32 to correct stepper movement to that rate.
I could I suppose have some way to set the "tune" speed. I don't want to use
commanded rate as many people when commanding a particular rate may be way
off that due to the conversion of values.
I'll look into it..
