I guess I'm lucky, I've only had maybe 15 stitches in my whole nearly 84 
years of life, all but 4 in fingertips that got someplace they shouldn't 
have. The other 4 were getting the babymakers disconnected 50 years 
ago..

This is True.

But I do have a knee that if it had acted up 50 years ago, would have  
been replaced 5 times by now. But I just keep a cane handy when I know 
I'm going farther than from one end of the house to the other. If I baby 
it, it might yet last as long as I. :)

I got that sorted too. See another post I made earlier. Now all I have to 
do is wrestle it back into its normal resting place in the shop 
building. Tomorrow if my back wakes up without too much complaining.  
The toolbox TLM is sitting on, and the toolbox are between 250 and 300 
lbs. Either that, or find a place on the motor power box for another BoB 
and wire up P2 on the 5i24 so I can have individual home switches.

Needed some script pills from Wallies, and looked for batteries for the 
laser that looks like a 38 cartridge. Oddball #393's, bought all wally 
had at $7 each. All they had was 4. I guess I'll have to find them 
online. Found a small ND10 at TSC to put in front of the camera. But 
dinner is in a skillet, brussel sprouts in the microwave, so not much 
more will be done yet tonight.

Take care Hubert.

The answer is a resounding no! Looking around I did find where to source 
that data.

That problem was easy enough to solve once I had applied a 3rd cuppa, the 
key is in the DRO's display modes. Put it in actual, machine mode, run 
it to where you want the soft limits, write down what the DRO says in 
RAD for x, and whatever it displays for Z, after of course homing the 
machine. Put those in the 2 places for each per axis n and joint n in 
the ini file. Restart LCNC and check. Works, but I've litterally a 
micron between the back of the crossfeed and the face of the x home 
switch and an all done, very solid mechanical stop, I had to move the 
limit out .05mm at a time to stop the limit disable while homing X.

But I hate to admit it, but when I copy/pasted the new Z section in my 
hal file, one paragraph of "get it from the ini" stuffs didn't get its 
0's rewritten with 1's. I spent over an hour running the z scale up 
about 20% at a time trying to make a g1 f50 Z-25.4 give me more 
than .776" of motion.

Anyway, I think TLM, subject to some possible following error tolerance 
adjustments, is ready to go again.

===

Now I need to see if I can remove the camera lens, and find a chunk of 
ND10 to cover it, and find out if I have a camera with a big enough 
image chip in it to make this 38 cal laser thing actually workable.

No, I was looking in the pins tab, but was looking for 
joint.1.motor.pos.cmd, which does not seem to exist.

Because theres no motor power though, I can look from here. And 
joint.1.motor-pos-cmd does exist now...

I finally received those 2 laser cartridges today, and must say they are 
gawdawfull bright, but the beam is a good 2 to 3mm wide just an inch or 
so from it, and nowhere near a round circle. It does appear to be well 
colimated as its not a lot bigger on the wall 7 feet away. With an ND10 
welding glass in front of todays camera chips after the lens itself has 
been removed, the spot may be bigger than the imaging chip! Time to 
clear a spot behind the lathe for a table and monitor.  And go trolling 
the likes of tractor supply for a small ND-9 or ND-10 welding mask 
filter. Let the fun begin!

Thanks Andy.

In fact, even without a 5i25 that pin should exist.

If num_joints was set to 1 then you wouldn't have that pin. Otherwise
I suspect that you are looking in the wrong place. Signals rather then
Pins tab?

Since is the 1st 5i25 I've put in service quite a few years back,
and it is supposed to have a 5i25_prob_rfx2.bit file in it, same as
in my G0704 mill, I thought I'd verify it, but didn't get too far.

This command line:

sudo mesaflash --device 5i25 --verify 5i25_prob_rfx2.bit

0x10, but gets an 0x00 and exits with the error.


You cannot in general verify stored bitfiles against current bitfiles
as even a re-compile will change the bitfile contents so verify will
fail.


Do I have a forgetfull card?  Or is it actually programmed to some
other bitfile? This, being the original card I bought, was
preprogrammed when I ordered it all those years ago.

How should I proceed?


No need to do anything really, a card cannot forget even a single bit
or it will not load the firmware from the flash chip (it will have a
CRC error and fallback to the alternate configuration which 1. Will
blink the red INIT light, 2. Is a justio config that has nothing but
GPIO)


In that event, where are the missing pins?


Which missing pin? you only listed a missing pin from motion, not hardware



Z moves normally when the key is held down. Then runs on for an
additional distance in the same direction.  A 6.35mm move, moves the
6.35mm's, then drops to about .001mm velocity for an additional 9 thou
at which point the pos-cmd and motor-pos-fb finally match.  And its
cumulative, ask it to move an inch (25.4mm's) at 500mm/min and it moves
at that speed, then virtually stops, taking around a minute to arrive at
matching counts, which can be an additional move of more than 20 thou at
the end of the high speed move. So I have no instant control and that
kills homing. The esc and f2 keys are ignored during this ultra slow
final move.



Sounds like a stepgen setup/tuning issue



I'll do some more checking but that would be a lot easier to see if I
could turn off geany's color as most of the vars and pin names are
