was going to call you...
How's the machine running these days with emc2?
rather well....it is really nice to have tool length
Good. So it does work like it should?
actually did something today with 5 different tools and they all were in the right place....length wise that is
That is good news. Means that it will be working properly with the Mazak at fest.
with tool change that should be IMPRESSIVE
Almost like a real production machine.
After that we've got to get your mazak completed.
with the Al parts that Roland makes it should really scream
Yes it should.
rebuilt spindle and tool change would be slick
The only thing you'd lack would be the spindle encoder for rigid tapping.
I keep having fun with Synergy....wish more people were using it so I had someone to talk to
Synergy has a lathe code writer.
It may still be easier to get spindle encoder than fix the old alignment cam
Could you send me a 1/4-20 by 1" thread program.
there is no emc lathe post so you will get fanuc
Thanks. I'm looking for several of these for the wiki page. Got a mastercam one on the way.
it assumes G18
I thought BobS had written an EMC post?
not for lathe.
I use the mill one all the tme
If emc had threading I think he would. ....
who says it doesn't?
I'd bet so. And it does as of last night.
neat....that I could use...
Course cradek couldn't make a real thread with the ngc file he put in<g>
I just changed it
after I get the Mazak finished and the surface grinder going and the lathe converted.
I just fixed multiple spindle-synchronized moves (entry/cut/exit) and changed the example program to do that
I'm thinking of biting the bullet and getting a usdigital hollow shaft encoder that fits right over the 5/8 extension on the Sherline spindle.
are they super expensive?
Do you have it switching off feedrate override?
(and do they have low enough counts for software counting?)
64 is as low as they go
that's fine, I think you want about 400 pulses (100 full counts)
But the lashup is trivial. Two set screws to the shaft and a screw to hold the base.
emc should not have a problem with encoder rates ... on a card...now if you have to poll that is another matter
This is a parport implementation isn't it?
dave-e: these hobby machines are parport, and we can count on it - just not super fast
See you giacus
:-) ... virus scan indeed!
They have a 100 cpr
ray ... any way some of the 'hobby' machines could use the KM card?
that sounds like a really great solution other than the $220 part
Right. Anything less costly has a mounting problem cause it's the whole pulley on top that turns.
AD has a low end set of encoders...dust but not wash down.... for ~90 US
Yes but only an 8mm hollow.
and I want to be able to bar feed my lathe.
that is a problem without an extension
offset and belt drive....like the spindle on the mazak
Still trying to figure out how to automate the chuck.
Yea but then you got a $100 in parts and 4 hours to figure out how to mount the sucker.
"I want to be able to bar feed my lathe." Sounds like rayh lathe is a living breathing blood pumping beast! lol
And I had a bitch of a time the last timing belt pulley I bored.
A living breathing blood pumping beast of a Sherline.
This is a test setup for fest.
dave-e, As for the KM card, we would just have to write a HAL module to read it.
Probably could cut the encoder stuff from stg.
I believe that stg used the same encoder counter chips for a while.
I'd better get back to emccalib.tcl for a bit. Want to try to finish that up tonight.
rayh is now known as rayh_away
good day gents..
cradek: Is this what you use?

I eard this host sometime delete websites without apparent reason
Ill get a good hosting
but very good !
I hate middle way ..
bill2or3: yeah, google ads is also nice
but not in that space
theyr own offers banners, payforview or payforclick
they are offering theyr hown banners*
just vacuumed out my portables keyboard. - yeck. I have cats ;) one of the keys got vaccumed up also. oops.
Ihave a ? Im new to CNC I download ded emc for my controller (linux box) and on my Windows box I have Free mill if any one can tell me which post procsser in free mill is compatible for g code
needed by emc to function properly
* bill2or3 has never heard of "Free mill"
a freind has given me some stl. of parts that I would like to cut out
I got Freemill off the sherline site
* fenn was hoping one of the cats got vacuumed up too
i think fanuc usually works..
* skunkworks thinks the wife would kill me.
I will give it a shot tomorrow
emc is pretty standard - I would think fanuc would also work.
skunkworks: She won't KILL you, but you might not be getting any either
no - she would kill me.
skunkworks: Then enjoy while you're still alive
where the heck did that archive come from?
hmm i wonder why sherline didnt submit any of their patches
anybody interested in seeing a $0.49 servo motor complete with encoder???
* fenn hops around like a babboon
fenn thank you
* fenn bares his teeth at seanMc
tfmacz: where where?
[23:40:15] <tfmacz> http://ourplacepa.ca/cnc_machine/photos/servo_motor-6.jpg
sorry had to fine the url...
say, that's a honkin big $0.49 motor
or a teeny little vise
Honda heater fan motor and a optical encoder hacked out of a ps2 mouse
Hey... CNC a la autoparts store!
jmc knows that one
The mouse cost me a buck at the sally ann. still another encoder available.
[23:43:43] <tfmacz> http://ourplacepa.ca/cnc_machine/photos/servo_motor-5.jpg
that one is picture of the encoder output with the motor turning about 2200 rpm
how are you counting the pulses?
LawrenceG has a pic-servo drive that takes quadrature output from the computer and controls the servo. The pic is counting pulses.
cool.. how fast can it count?
is this with the dsPIC30F11
not sure... work fine up to 2400 rpm. havn't tried it any faster.
how many lines does a mouse wheel have?
really? mine only had like 32
so 1024 pulses per rev?
that's 40khz.. not too shabby
wheel has 64 openings.... can get 256 pulses/rev if counting all 4 edges
very common mouse... hp, compact, logitech all seem to use the same electronics
LawrenceG: how fast can the pic count?
i need 100khz
for a manual encoder
i was thinking of making a mpg out of a stepper motor
might be a fool's errand though
fenn: I havent looked at top rate... if you use a 30f4011 pic, it has a 16 bit hardware encoder interface
I am using that on another project and doing all the coding in C
that is pretty damn cool
have you guys completed the power stage yet?
for that matter, is the control board done? :)
i saw the wiki page a couple months ago
100khz might be doable, with a fast pic
* fenn has too many questions
30f4011 will do 30,000,000 24bit instructions a second
yup... pretty amazing... runs at 120mhz
heh i didnt know that part
* bill2or3 needs to re-learn pic's
and then some.
using 8mhz xtal and 16x multiplier
i'm playing around with avr's
the atmel stuff right?
what does avr stand for, anyway?
advanced virtual risc? or the authors initials.. but nobody knows for sure
I've played with the 16f84's a tiny bit, but I never really had a good setup to write the chips, so it was really clunky.
