I would add positioning moves (positioning all of XYZ) before the G33.1 because otherwise the tapped hole can be anywhere - the program is indeterminate.

Re: [Emc-users] Rigid tapping with geared encoder
Your intuition is right. If you don't care about starting in the same orientation each time, it doesn't matter. My VMC has the encoder on the motor, and it doesn't have an index at all. I wired the A to the Z input on the mesa card so it gets lots of indexes and the tapping starts wherever it happens to be. My lathes of course have real index.

First congratulations on your first big retrofit. Now for the opinions: As for the Z inhibit: are you using AXIS in LinuxCNC? The preview shows where the tool is going to go, so there's little need for running in the air. If you are concerned about getting close to a fixture, you can jog the cone over onto the preview line (a jog wheel is great for this) and then see where it will be when it runs. I think Z inhibit (and inhibit all) are on old controls because they didn't have useful previews. You had no idea what the code was going to do, or even if it would run or error or go crazy. My Boss8 would just hang (it would stop and you had to push the control's reset button on the back) for certain gcode errors, especially with canned cycles. But with LinuxCNC when you load your gcode you see a correct preview or an error message telling you what's wrong with it and where. So I encourage you going to LinuxCNC with an open mind and not trying to implement everything your old control had, whether it makes sense or not. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Weird - I'm pretty sure mine is a MP7, and it is turned on and off with a signal over the IR. I have the OMM+MI7 interface. Of course to receive the signal, some part of it has to be alive all the time, but it isn't sending and the battery lasts a good while. I have never spun it.

Re: [Emc-users] Running servo amplifiers in velocity mode vs. torque mode
On Wed, Mar 01, 2017 at 07:46:24AM -0600, dragon wrote: > better to run the servo amplifiers in velocity mode or torque mode. I I think the benefits of velocity mode are that it better tolerates (still gives smooth motion with) low encoder resolution and low servo cycle update rates, and it's much easier to tune the position loop (the part in linuxcnc/hal). Some old CNCs had 100Hz servo cycles and fairly rough position feedback. If you didn't want to see stair steps on the taper you were cutting on your lathe, you really wanted velocity mode so it would keep moving in about the same direction between updates. The drawback of velocity mode is the amp is much more complicated, and you have to tune the velocity loop in the amp, and you might even need extra parts, such as tachs, to give velocity feedback in hardware. Today with millisecond or faster servo cycles, and really fine encoders, I bet you can get similar results with both setups. If you can select with a switch, why not try tuning up an axis both ways and see what works best? I'd love to see your results if you do this.

I would sure do this with ladder. You can use rising-edge (the ones that look like -|^|- ) to trigger timers that poke your relays for the appropriate amount of time. I bet you will end up with interlocks, etc, that are really easy to do in ladder, and totally possible but really tedious to do in bare hal. Ladder has a learning curve but for any nontrivial machine (does it have a tool changer?) it's worth your time to learn it anyway. The other answer is probably to use a bunch of oneshot components, but consider what happens if you turn the spindle on and then immediately off - if they're not carefully interlocked you'll end up poking your M3 and M5 signals at the same time (which may or may not be ok...?)

If I understand right, you want to move the table manually while the spindle is running. You've gone down the path of wanting to trick linuxcnc into being in machine on mode even though the amps are disabled, so you can tell it to turn on the spindle. But the better solution is to leave linuxcnc in machine off mode, which disables the amps and gives you a working DRO, and more importantly, the position tracks so when you go back to machine on you don't get a nasty position jump or any other weirdness. So the problem remaining is that linuxcnc won't turn on the spindle in this mode. Right, so poke the button on the VFD that makes it come on, or install a (real actual) switch. Chris -- New Year.

I feel it's the job of the proposer to lead the discussion and make the persuasive arguments in the time between meetings, and then explain and summarize that work at the meeting. I guess I was imagining that if the proposer was still wanting a certain thing to happen, and the proposal is tabled one month, that person would continue to place it on the agenda and, between meetings, do the work to rally support.

If you're doing the work of cheerleading a proposal, editing the agenda once a month to keep your idea active seems like a very low bar.

With the system you propose, I think there will be more no votes when proposals are made that nobody really does the community work for.

Interesting machine!
We are having trouble getting it to work in EMC. When we turn on the
machine in EMC, both carriages immediately race at full speed towards the
home switches.
There should be no motion until you home. Since it comes up in
joint mode, your kinematics are not even running.
Using the MDI tab with G code commands we are able to get X motion at the
pen. That is pretty simple because for X, both carriages always run at the
same speed and direction as the pen. We can command the pen to move in Y,
but only at very low speeds. If we try to go fast EMC gives us all sorts of
joint speed and position errors.
As has been pointed out, you should record and report behavior a lot
more carefully if you are asking for help.
There is a link to our kinemantics file at the link above. (We just
modified trivkins.c). At this point I think it has been hacked beyond our
initial successes, to completely broken.
1. For this type of machine, what do we return for kinematicsType()?
BOTH as you have done
2. What do I want to do in kinematicsHome(). When is this function called
and how often?
Never as far as I know
3. Why does the machine starting running immediately.?
Not enough information to say.
4. Can everything be done in the mykin.c file or do I need to modify other
areas of the HAL.
I don't think you need to do anything else. I grabbed the latest??
version of your file which says it's untested. (It's hard to tell
which version others have tested). I made a similar test program
that could be run outside LinuxCNC (I absolutely recommend testing
kins standalone):
#include math.h
#include stdio.h
#define sq(x) ((x)*(x))
double c2 = 140.4225;
double x,y, j[2];
void f(void) {
double b = (j[1] - j[0]) / 2;
x = j[0] + b;
y = sqrt(c2 - sq(b));
}
void i(void) {
double b = sqrt(c2 - sq(y));
j[0] = x - b;
j[1] = x + b;
}
void p(double x, double y) {
printf(%g %g);
}
int main(void) {
x = 3, y = 4;
t();
x=4;
t();
y=5;
t();
x = -1, y = -2;
t();
x = 0, y = 0;
t();
return 0;
}
The output looks correct to me, for the expected domain:
start point: 3 4
-8.15448 14.1545
3 4
start point: 4 4
-7.15448 15.1545
4 4
start point: 4 5
-6.74349 14.7435
4 5
start point: -1 -2
-12.68 10.68
-1 2
start point: 0 0
-11.85 11.85
0 -nan
For the positive numbers, start - inverse - forward - compare
gives a match, so your inverse and forward kins match. This is
good. Moving the controlled point right increases both joints;
moving it up increases one and decreases the other.
As others have said, you have to be careful about invalid input
values, such as negative Y. Notice that 0,0 is also bad and you
need to avoid it. You will have to set your world limits carefully.
Set your machine on graph paper or similar, with the origin at one
end of the rail and move it around by hand to see where the pen can
actually reach. Set those as your axis limits. Wildly guessing
from your photo you'll get something like X 15..30 and Y 3..10 if
you're in inches. Your real constraints are not rectangular, but
you'll need to inscribe a rectangle and use that.
Set up joint homing however is convenient, and note the resulting
world position once homed. That has to be given in the ini file.
I am not really sure how you can home this safely - you'll have to
be creative and it'll probably involve a homing sequence or even
pre-positioning by hand.
I cannot guess what causes your initial runaway, but I suspect
you've got a problem with your homing procedure that leads to
invalid numbers being sent through your kins.
On a normal trivkins cartesian machine we can be fairly lazy about
homing since it only sets our axis travels and all points in world
space correspond to (matching) points in joint space. In a machine
like yours, homing is really bootstrapping the machine and getting
the world command, joint command, and kins loaded with numbers that
make sense and correspond to each other.
You should share your whole config (tar it the directory) for better
help... Also be sure to say what version of LinuxCNC you are using.
This is cool and I hope you get it going.

Thanks! If you can find wiring diagrams you can determine a lot about whether it's a good candidate for conversion. A 1991 machine will probably have velocity mode amps with tachs, and LED-based encoders. So no real problem there. I'm guessing it's 40 taper - I would rather have a CAT spindle with retention knobs but those NST (NMTB?) aren't rare or anything. Mostly, good candidate means its drives and motors and encoders all work, and it's not mechanically worn out. If you take your indicators with you and it's under power and operable you'll know all that in short order. If it's not under power and you can't convince them to plug it in (I bet you $1 that's what you'll encounter here) you can tell a BIT about wear by pushing and pulling the table (compare readings in the center of travel to readings at the ends of travel) and by turning screws by hand (you'll feel and see any backlash). Something about the machine looks familiar. I think it might be the same base model as Stuart's Dah-Lih. If so, there are power drawbar parts missing. I notice there's no tool release button marked on the panel. I would really NOT want a manual drawbar on a CNC, especially if the top of the head's 8 feet in the air. (If your hackspace has 8 foot ceilings, take a tape measure with you!) This machine has a heavy knee and I notice there's no motor on it.
