Only slightly interesting since I have used geany as my goto editor since 
I had so much trouble with gedit playing 52 pickup with my code.  geany 
hasn't trashed a file that wasn't blamed on pebkac by me. gedit did it 
at least once in 10 edit sessions. I got /damned/ tired of restarting a 
600+ LOC .hal file because gedit destroyed it.

geany has highlight and error checking settings for quite a few code 
languages, and apparently can do folding at a label while working on 
an .ini file.  I just found that out yesterday after noting that some 
code I was running, and I had the stick clamped to project left of the 
vise, and which puts the table to the right about a foot, had slipped 
the X about 3/32" halfway thru the run.  I let it finish, and fixed the 
damage with a chisel.

It was a test cut in sweet gum, no great loss, as I was working on a 
routine to function as a socket cutter for a Rockler Lid Stay hinge, 
which is built to work on the edge of an S4S 1 by board, but my trim 
piece that sits on top of the edge of that board is 1.5" wide. It is 
there to hold the top ends of the cedar plank lining I'm putting in, 
with a small groove about 5/16 wide in its bottom face that the ends of 
the planks set into.

Anyway, I cleaned up the black gunk on the X ways and re-lubed them with 
Mobil Vactra 68, then decided to slow the accels and max vel on X about 
20% to put off the next occurance of that stiction.  And not knowing 
geany had folded at the [axis 0] label, I changed the Y stanza some.  
That fold was a pebkac, but a click on the [+] mark in the left margin 
fixed that.

But when I gave it up for the night out there after doing that, I came in 
here, and did a utube search for g0704, and found Hoss's ramblings about 
putting some lub facilities in a g0704.  And one thing I noted right 
away was that his machine was moving at least at 150ipm.  Mine, with 
this motor kit has never moved x or y faster than 72 ipm without x 
stalls when the table is at the end of its travel.

This kit uses 2M542 xy drivers and a 40 volt supply. I could probably 
turn the voltage up some, but what I saw Hoss's machine doing is simply 
not possible on mine.  Z, has a nema 34 motor and 80 volt controller 
running on 60 volts, and its stallable if I ask it for more than 42 ipm 
going up even with the ways loose as a goose. Lifting that 
non-counterbalanced head is hard work even for that 1600 oz motor.

Hoss's xy motors look like the same triple stack nema 23's I have, rated 
at about 470 oz/in.  So how the heck is he getting his to move that 
fast?

So I believe I now have it running dependably again, but slower rapids 
are going to add to the execution time per hinge socket carved.  Not 
counting tool changeing time, 2 of those, its 21 minutes right now. 
Probably by the time I fool around touching off x as I move the board 
strip in the vise to get to the next position to cut, close to 30 
minutes per hinge, 3 hinges.  I think I can cut that some in the Y moves 
(all this is climb cutting) by not using a fixed clearance point for the 
x retrace move, but just clear the Y face 20 thou on the x retrace move.  
#<_tool_rad> seems like enough clearance. I can do that from here, and 
will before another test run, in addition to adding the 3rd tool change 
and pecking those 3 countersink locations.

Because these hinges, at 60 oz/in friction, exert so much force on the 
wood, and only have provisions for a pair of #7 screw about 1.25" long 
thru the top, and a pair of #7 3/4" long thru the wrap-around tab, I'll 
add 3 more screws under the hinge, #8x3 fine thread drywall screws whose 
heads will be sitting flush or just below the top of the wood and hidden 
by the hinge when its placed, and 2 more of that screw to replace the 
smaller one rockler supplies. I have a sharp pointed roundover bit that 
will do a decent job of cutting that countersink, so I am tempted to add 
that to the machining just so I have a good place to aim a pilot drill 
as I'm installing all those screws while racing to get it all snugged up 
before the glues "open" time is used up, about 15 minutes, so I'll have 
to drill ALL the pilot holes first.  Fun & games I won't try when I am 
tired & hurting.

Nother not so silly Q: LCNC skips the tool change if that tool is still 
loaded from the last run.  Thats nice, but how do I add the z run up to 
the tool change height to the conditional T#M6G43, so the M6 only runs 
up the pole if it has to actually change the tool?

At 25 to 35 ipm, there's at least 30 seconds I could take back out of the 
execution time.  Thats worthwhile.

Thanks John.

Cheers, Gene Heskett
